You need to match the door hardware grade to your building’s usage, security needs, and budget. Choosing the right grade increases safety, durability, and compliance with regulations. The following table shows how different lock grades perform in safety tests, helping you understand why the right choice matters:
Lock Grade | Cycle Test | Vertical Load Test | Torque Test (Knob) | Torque Test (Lever) | Impact Test | Latch Bolt Strength |
|---|---|---|---|---|---|---|
Grade 1 | 800,000 | 360 pounds | 300 pounds per foot | 700 pounds per foot | 2 blows at 60, 90, or 120 pounds | 1,200 pounds |
Grade 2 | 400,000 | 250 pounds | 150 pounds per foot | 450 pounds per foot | 2 blows at 60 or 90 pounds | 600 pounds |
Grade 3 | 200,000 | 150 pounds | 120 pounds per foot | 225 pounds per foot | 2 blows with 60 pounds | 600 pounds |
Pick the right door hardware grade for your building. Think about how you use the building, how much security you need, and your budget. This helps make your building safe and strong.
Learn about the ANSI grade system. Grade 1 gives the most security. Grade 2 works well for normal use. Grade 3 is good for light use.
Always look at the ANSI grade when you buy door hardware. This makes sure it is safe and good quality.
Think about how many people use each door. Doors with lots of people need stronger hardware. Strong hardware lasts longer with heavy use.
Match the hardware grade to what the door does. Entry doors need Grade 1 for safety. Inside doors can use Grade 2 or 3.
Buying better hardware costs more at first. But it saves money later because you fix or replace it less often.
Make sure your door hardware follows local building rules. This helps you stay safe and avoid legal trouble.
Talk to experts like D&D Hardware. They can help you pick the best door hardware for your building.
When you want to know how is door hardware graded?, you look at the ANSI grade system. This system is made by the Builders Hardware Manufacturers Association and the American National Standards Institute. The ANSI grade system helps you see how strong and safe your door hardware is. There are three main grades: Grade 1, Grade 2, and Grade 3. Each grade shows how well the hardware does in tests for safety, strength, and quality.
You can check the main rules for the ANSI grade system in the table below:
Criteria | Grade 1 Requirements | Grade 2 Requirements | Grade 3 Requirements |
|---|---|---|---|
Test Cycles | 1,000,000 | 800,000 | 800,000 |
Force to Latch | Maximum of 4.5 pounds force | Maximum of 4.5 pounds force | Maximum of 4.5 pounds force |
Strength Test | 360 pounds applied on lever | 360 pounds applied on lever | 360 pounds applied on lever |
Security Test | 75 ft.-lbf (100 J) 10 Blows | 75 ft.-lbf (100 J) 5 Blows | 75 ft.-lbf (100 J) 2 Blows |
Material Evaluation | 0.075 in. (1.9 mm) | 0.100 in. (2.5 mm) | 0.100 in. (2.5 mm) |
Finish Tests | All grades meet same standards | All grades meet same standards | All grades meet same standards |
The ANSI grade system checks how many times you can use the hardware before it breaks. It also tests how much force the hardware can take and how well it stands up to attacks. Grade 1 hardware must pass the hardest tests. Grade 2 and Grade 3 do not have to pass as many tough tests.
It is important to know how is door hardware graded? because it helps you pick the right hardware for your building. Hardware grades tell you how much safety and strength you get. If you choose the wrong grade, your hardware might not protect you or last long.
You should buy products that meet international standards. D&D Hardware makes sure all products meet ANSI, BHMA, UL, and CE standards. These rules cover fire safety, sound blocking, and security. For example, ANSI grade standards check test cycles and force, while UL and CE standards look at fire safety and approval. You can trust D&D Hardware because their products pass hard tests for safety and quality.
Tip: Always check the ANSI grade when you pick door hardware. This helps you find the right hardware for your building and keeps your property safe.
Now you know how is door hardware graded? You see that hardware grades and ANSI grade standards help you make good choices for safety. D&D Hardware gives you certified products that meet all the big standards, so you can feel sure about your choice.
When you pick door hardware, you need to know how each grade works. The right grade helps your building stay safe and last longer. It also gives you good quality. You can look at the table below to see the main differences:
Feature | Grade 1 | Grade 2 | Grade 3 |
|---|---|---|---|
Durability (Cycles) | Up to 1 million | Around 800,000 | Around 200,000 |
Resistance to Force | Up to 250 pounds | Around 150 pounds | Around 120 pounds |
Material Quality | Heavy-duty, robust metals | Moderate durability materials | Lightweight materials |
Usage | Commercial/High traffic | Residential/Light commercial | Interior/Light use |
Cost | Higher | Moderate | Lower |
Grade 1 hardware is the strongest and lasts the longest. You find it in places that need the most safety and strength. It meets tough rules for high-security places.
Banks, hospitals, and schools
Main doors in big buildings
Fire exits and escape doors
Places with lots of people going in and out
Pick grade 1 if you want the best safety and long life.
D&D Hardware sells many grade 1 products. You can get stainless steel locks, lever handles, door closers, and exit devices. All these pass ANSI, UL, and CE tests. You get strong and safe hardware for every job. These work on metal, fire-rated, and wooden doors. You can trust D&D Hardware for safe products in tough places.
Grade 2 hardware gives you good quality for a fair price. You see it in places that need to last but not as much as grade 1. It meets rules for many buildings.
Office doors and classrooms
Apartment entry doors
Small business spaces
Places with some people coming and going
Use grade 2 if you want good safety and quality for daily use.
D&D Hardware has many grade 2 products. You can find mortise locks, tubular locks, lever handles, and door closers. Each one passes ANSI and CE tests. You get strong hardware for new buildings or upgrades. D&D Hardware’s grade 2 works well in schools, offices, and apartments.
Grade 3 hardware is best for light use and home doors. You see it where you do not need much strength or safety. It meets basic rules for houses.
Inside doors in homes
Closets and bedrooms
Places with little use
Use grade 3 for rooms that do not need strong or tough hardware.
D&D Hardware sells grade 3 hardware for homes. You can pick door handles, locks, and hinges. All pass ANSI tests for safety and quality. Grade 3 hardware is a good choice for light-use doors. You get hardware that works well and is easy to put in.
Tip: Always choose the hardware grade that fits your building. This helps you get the right mix of quality, strength, and safety.
When you choose door hardware, you need to look at how your building works every day. Start by thinking about the main activities in your space. Ask yourself, “How many people use each door?” and “What type of doors do I have?” These questions help you find the key factors for choosing the right grade.
You should check the traffic levels for each door. Some doors open and close hundreds or even thousands of times a day. Others only get used a few times. High-traffic areas, like main entrances or busy hallways, need stronger hardware. Low-traffic doors, such as storage rooms, can use lighter grades.
Main entrances in busy buildings may see up to 5,000 cycles each day. These doors need Grade 1 closers and locks for durability and safety.
Office hallway doors often get 100 to 200 cycles daily. Grade 2 hardware works well here.
Home bathroom doors usually get about 25 cycles a day. Grade 3 hardware is enough for these spaces.
You also need to think about the door type. Metal doors, fire-rated doors, and wooden doors all have different needs. Some doors face moisture or high humidity. In these cases, you should pick corrosion-resistant finishes. Always consider environmental impact, life-safety, and emergency egress when you make your choice.
Tip: For high-traffic areas, choose hardware that can handle lots of use. This helps your doors last longer and keeps everyone safe.
Security is one of the most important things to think about. You want to protect people and property. Start by looking at each door’s purpose. Entry doors and interior doors have different security needs.
Entry doors need the highest level of security. These doors face the most risk from break-ins or forced entry. You should use Grade 1 locks and closers for main entrances, exits, and any door that leads outside. For extra protection, use anti-snap and anti-drill cylinders, multi-point locking systems, and reinforced strike plates. These features help stop common attacks and keep your building safe.
The solution? - Anti-snap, anti-drill cylinders (like BS Kitemark-certified locks). Multi-point locking systems spread force across several bolt points. Keyless entry works well for places with many users, such as apartment buildings or co-working spaces. Pro Tip: Pair these with reinforced strike plates to strengthen weak door frames—a common problem in forced entries.
Interior doors have lower security needs. You can use Grade 2 or Grade 3 hardware for offices, classrooms, or storage rooms. Always match the hardware grade to the security level you want for each space.
You need to balance your budget with the need for long-lasting hardware. Sometimes, spending more at the start saves you money later.
Grade 1 hardware costs more at first, but it lasts much longer. It can handle up to 500,000 cycles. Grade 2 hardware is rated for 250,000 cycles. If you pick higher-grade hardware, you will spend less on repairs and replacements over time. This means lower maintenance costs and fewer problems.
Grade 1 hardware may cost 35 to 50 percent more than lower grades.
The extra cost gives you better longevity and fewer headaches.
You get more value because your hardware works longer and needs less care.
When you plan your project, think about the total cost, not just the price you pay today. Investing in quality hardware helps you meet safety and security needs for years to come.
Note: D&D Hardware offers many options for every budget. You can get certified products that match your needs for security, safety, and longevity. Their team can help you choose the best solution for your building.
When you pick door hardware, you should think about more than just how strong it is. The way your hardware looks is important, too. You want your building to look nice and follow safety rules. The right design can make your space feel friendly or stylish. You also need to follow building codes for safety.
You can choose hardware that matches your building’s style. Each style has its own look and finish. Here is a table that shows which finishes work best for each style:
Architectural Style | Hardware Characteristics | Recommended Finishes |

Farmhouse | Rustic look, old-style finishes | Oil-rubbed bronze, weathered brass |
Victorian | Fancy patterns, pretty decorations | Brass, antique |
Contemporary | Mixed styles, cool shapes | Matte black, brushed stainless steel |
The right finish and design help your building look great. For example, a modern office might use shiny chrome handles. A farmhouse home could use dark bronze handles. Picking the right hardware makes your space feel complete.
But you also need to think about safety. Every building needs different security. Entry doors need strong locks and handles. Inside doors may not need as much security, but they should still work well and look nice. Always check that your hardware follows fire safety and emergency exit rules.
Building codes tell you what you must do to keep people safe. You need hardware that meets standards like ANSI, UL, and CE. These standards test for fire safety and strength. If you do not follow these rules, you might have trouble with inspections or insurance. Always pick hardware that meets or goes beyond these standards.

It is important to know lock grades when picking commercial door locks. Lock grades tell you how strong and safe your locks are. Each grade works best for a certain door and security level. The table below shows the main differences:
ANSI Grade | Description | Recommended Use |
|---|---|---|
Grade 1 | Heavy Duty Commercial | High-security, high-traffic areas like schools and hospitals |
Grade 2 | Standard Duty Commercial | Offices, interior commercial doors, moderate security needs |
Grade 3 | Light Duty Commercial | Low-traffic, low-security interior doors |
Grade 1 commercial door locks give the most security. Use them for main entrances, exits, and places where safety is very important. Grade 2 commercial door hardware is good for offices, classrooms, and inside doors that need some security. Grade 3 commercial door locks are for rooms with little use and low security, like closets or storage rooms.
You should match lock grades to what each door does. For example:
Lock Function | Best For | How It Works |
|---|---|---|
Storeroom Lock | Storage rooms, utility closets, janitorial areas | The door stays locked; you need a key to open it. |
Classroom Lock | Schools, training centers, educational facilities | You can lock or unlock from outside with a key, but always exit freely inside. |
D&D Hardware has certified commercial door locks for every grade and door type. You can get advanced locks for high-security places and regular locks for everyday doors. All products meet strict door lock standards like ANSI, UL, and CE.
You want to pick the right commercial door lock for each room. Here are some tips to help you choose commercial door hardware:
Learn about lock grades. They show how strong and safe your commercial door locks are.
Grade 1 commercial door locks are the strongest. Use them for main doors, exits, and busy places.
Grade 2 commercial door hardware is good for offices, classrooms, and inside doors with medium security needs.
Grade 3 commercial door locks work for rooms with low risk and little use. Do not use them for main doors or outside doors.
Always check if your door is outside or inside. Outside doors need more security and better locks.
Think about how often people use the door. Busy doors need stronger commercial door locks.
Make sure your locks meet door lock standards. D&D Hardware’s products follow commercial lock standards for safety.
Commercial buildings need higher-grade commercial door hardware because they have more people and bigger security risks. Homes can use lower-grade commercial door locks if they do not need much security. Always match the lock grade to the door’s job and the safety you want.
Tip: When you pick commercial door locks, always check the grade, the door’s job, and the door lock standards. This helps keep your building safe and follows the rules.
D&D Hardware gives you many choices for commercial door hardware. You get certified door locks for every need, from strong entry doors to light-use inside doors. You can trust D&D Hardware for safe, high-quality, and advanced locks that fit your building.
