Are you looking for a simple way to boost privacy or add a bit more security to your doors? Many homeowners choose a barrel bolt for these reasons:
It resists forced entry and keeps rooms private.
You can use it on bathroom doors, sheds, or even gates.
It works well for families since anyone can slide it—kids and seniors included.
It needs only basic tools and a few minutes to install.
You will find this detailed guide easy to follow. D&D Hardware, a leading door hardware manufacturer in China, offers a wide range of reliable products to meet your needs.
Collect all tools and materials before you start. This helps you save time and stops interruptions.
Mark and line up the barrel bolt and strike plate with care. This makes sure the lock works smoothly.
Drill small pilot holes first. This keeps the wood from splitting and makes it easier to put in screws.
Use wood blocks or longer screws if your door is uneven, bent, or hollow. This gives better support.
Test the bolt after you finish installing it. Change the strike plate if you need to for a perfect fit and smooth use.
Before you start, you want to gather all the things you'll need. This step saves you time and helps you avoid searching for tools in the middle of your project. Here's a quick guide to help you get ready.
You do not need fancy equipment for this job. Most of the things you'll need are probably already in your toolbox. Here's a handy checklist:
Screwdriver (Phillips or flathead, depending on your screws)
Drill (for pilot holes)
Tape measure or ruler
Pencil or marker (for marking positions)
Safety glasses (to protect your eyes)
Work gloves (optional, for extra grip)
Tip: If you do not have a drill, you can use a screwdriver, but it may take more effort. Always wear safety glasses when drilling.
You want to make sure you have the right materials before you begin. Here's what you need:
Material | Purpose |
|---|---|
Barrel bolt | The main locking mechanism |
Screws | To secure the bolt and plate |
Strike plate | Catches the bolt in the frame |
Wood block | For uneven or hollow doors |
Adhesive (optional) | For temporary placement |
If you buy a barrel bolt kit from D&D Hardware, you will get most of these items in one package. D&D Hardware is a trusted fire door hardware supplier in China. They offer a wide range of door bolts, locks, and other hardware for every need.
First, decide where you want to place your barrel bolt. Most people install it about halfway up the door, but you can choose a spot that feels right for you. Use a pencil to make a small mark on the edge of the door. This mark shows where the main body of the bolt will sit. If you want extra security, you can add a second bolt near the bottom.
Tip: Stand back and check your mark. Make sure it lines up with the door frame. A crooked bolt will not work well.
Grab your tape measure or ruler. Measure from the floor to your mark. Write down the number. Now, measure the same distance on the door frame. Mark this spot. This helps the bolt and strike plate line up. Place the barrel bolt on the door. Hold it steady. Trace around it with your pencil. You now have a guide for drilling.
Here's a quick checklist for this step:
Mark the door and frame at the same height
Trace the outline of the bolt
Double-check your marks before drilling
Not all doors are perfect. Some may be hollow, warped, or have an offset frame. If your door feels uneven, do not worry. You can use a small wood block behind the bolt to create a flat surface. This trick helps the bolt sit straight and work smoothly. For hollow doors, pick a spot near the edge where the wood feels solid. If you cannot find one, use longer screws or wall anchors for extra hold.
Problem | Solution |
|---|---|
Hollow door | Use longer screws or anchors |
Warped door | Add a wood block for support |
Offset frame | Adjust position for alignment |

Ready to get hands-on? Let's walk through how to install a sliding bolt on your door. You already have your tools and materials. Now, follow these steps for a smooth installation.
You want to start by making pilot holes for your screws. This step keeps the wood from splitting and makes it easier to drive in the screws.
Hold the barrel bolt against the door where you traced its outline.
Use your pencil to mark the screw hole positions through the bolt's mounting holes.
Choose the right drill bit size for your screws. Here's a quick guide:
Screw Size | Pilot Hole Size for Hardwoods | Pilot Hole Size for Softwoods |
|---|---|---|
#6 | 3/32" | 5/64" |
#8 | 1/8" | 3/32" |
#10 | 1/8" | 7/64" |
Drill each pilot hole to the full depth of the screw. This helps the screw go in straight and prevents the wood from cracking.
Safety Tip: Always wear safety glasses when drilling. Keep your work area clear. Tie back long hair and secure loose clothing.
Now, it's time to attach the main part of the barrel bolt to your door.
Place the barrel bolt back on the door, lining up the holes with your pilot holes.
Use wood screws for a solid wood door. These screws come in most barrel bolt kits and work best for wood surfaces.
Hold the bolt steady and drive in the screws. Start with one screw, then check the alignment before adding the rest.
If your door is hollow or uneven, use a wood block behind the bolt for extra support.
Tip: If you find the screws hard to turn, rub a little soap or wax on them. This trick makes them go in easier.
Some people ask about alternatives if you can't use screws. For metal doors, rivets or lag bolts with nuts can work. Adhesive or clamps might hold the bolt temporarily, but screws give the best security.
The strike plate is the part that catches the bolt when you lock the door. Getting this piece lined up is key.
Slide the bolt into the locked position. Mark where it touches the door frame.
Hold the strike plate (sometimes called the bolt holder) on the frame, matching your mark.
Trace around the plate with your pencil.
Use a chisel to make a shallow recess so the plate sits flush. Tap gently and remove small bits of wood.
Mark the screw holes for the strike plate.
Drill pilot holes for these screws, just like you did for the bolt.
Attach the strike plate with screws.
If the bolt doesn't slide smoothly, adjust the plate's position. Sometimes, you need to file the opening a bit wider or move the plate slightly. Always test the fit before tightening all the screws.
You're almost done! Now, check your work.
Slide the bolt back and forth a few times. It should move easily and lock into the strike plate.
Close and open the door to make sure nothing sticks.
If the bolt doesn't line up, loosen the screws and adjust the strike plate. Tighten everything once it works smoothly.
Pro Tip: If you ever need to move the strike plate, fill old screw holes with wood filler. Let it dry, sand it smooth, and drill new pilot holes.
You've just finished the main steps to install a sliding bolt. This method works for most wooden doors. For metal doors, the process changes a bit. You'll need to drill through the metal and use special bolts or rivets.

Sometimes, you finish installing your barrel bolt and it just doesn't line up right. Don't worry—this happens to a lot of people. Here are some common mistakes that can cause misalignment:
You might not tighten the screws enough, which makes the bolt loose and wobbly.
If you overtighten, you can strip the threads or twist the bolt out of place.
Sometimes, you don't seat the bolt flat against the door, so it sits crooked.
Cross-threading screws can damage the holes and make the bolt sit unevenly.
If the bolt or strike plate isn't lined up with your marks, it won't latch.
To fix misalignment, try these steps:
Loosen the screws and gently adjust the bolt or strike plate until they line up.
Use a screwdriver or drill to retighten, but don't overdo it.
If the holes are damaged, fill them with wood filler, let it dry, and drill new pilot holes.
For stubborn problems, remove the bolt and start over, making sure everything sits flush.
If you still can't get it right, check if the door or frame is warped. Sometimes, the problem isn't the hardware!
Warped or hollow doors can make installing a barrel bolt tricky. Warped doors don't always touch the frame evenly, so the bolt may not reach the strike plate. Hollow doors have thin wood, so screws might not grip well.
For warped doors, try moving the hinges outward or adjusting the doorstop. This helps the door close flat.
On hollow doors, use longer screws or add a dab of epoxy for extra hold. If the screws still won't grip, you might need to move the bolt to a sturdier spot.
Always drill pilot holes that fit your screws. Too big, and the screws won't hold. Too small, and the wood might split.
Problem | Quick Fix |
|---|---|
Warped door | Adjust hinges or doorstop |
Hollow door | Use longer screws + epoxy |
Loose hardware | Try continuous hinges |
If you need heavy-duty hardware for tough doors, D&D Hardware offers solutions for all kinds of tricky installations.
Door trim can get in the way of your bolt or strike plate. If the trim is too thick, the bolt might not slide in all the way. You can fix this by:
Filing or trimming the strike plate opening.
Moving the strike plate slightly up or down.
Using a chisel to recess the plate deeper into the frame.
Take your time and test the bolt after each adjustment. Small changes can make a big difference.
