EN12209 Bathroom Door Lock Supplier Fire Resistance Pravicy Mortice Locks for Doors-DDML012

Product Features

1. Authoritative certification, safe and reliable
This bathroom door lock is BS EN12209 and DIN 18251 Grade 3 certified, and has been tested for 200,000 cycles to verify its durability and meets European door lock industry standards. EN1634 certification indicates that it has a fire resistance of 260 minutes, which can maintain structural integrity in high-temperature environments, providing fire isolation protection for bathrooms. The 240-hour corrosion resistance test certified by EN1670 ensures that the lock body does not rust for a long time in humid environments, meeting the special needs of bathroom scenarios.

2. Precise parameters and strong adaptability
The backset of the lock body is 60mm, and the distance from the lock cylinder to the edge of the door meets the mainstream door installation standards. The door margin (Distance) is 78mm, ensuring that the deadbolt and the door frame locking plate are accurately aligned, reducing installation errors. Square or radius deadbolt and latch design can be adapted to different styles of bathroom doors and enhance the overall aesthetics.

3. High-quality materials, sturdy and durable
The deadbolt, bolt and follower are made of solid SUS 304 stainless steel, which has strong impact resistance and can withstand high-frequency use without deformation. The deadbolt plate (Forend) and the strike plate are also made of SUS 304 stainless steel, and the surface is brushed (SSS), which not only enhances the anti-corrosion performance, but also gives the product a modern and simple visual effect.

4. Fireproof design, safety upgrade
The EN1634 certified 260-minute fire resistance makes the bathroom door lock effectively block the spread of fire in the event of a fire and buy time for personnel evacuation. The internal structure of the lock body is filled with fireproof materials, and the key components are specially treated to ensure normal operation in high-temperature environments and improve the overall safety of the bathroom space.

5. Corrosion-resistant process, long-lasting as new
According to the EN1670 standard, the surface of the lock body is salt spray tested for 240 hours, which can resist the erosion of corrosive substances such as water vapor and detergents that are common in bathrooms. SUS 304 stainless steel material combined with brushed surface treatment (SSS) creates a double protective barrier, extending product life and reducing maintenance costs.

Maintenance

1. Regular cleaning to maintain a smooth surface

Wipe the surface of the lock body with a soft cloth every week to remove water stains, dust, and other dirt. Avoid using cleaning agents containing abrasives to prevent scratching the brushed stainless steel surface. When cleaning, pay attention to the contact area between the lock tongue plate and the lock buckle plate to ensure that there are no foreign objects obstructing the expansion and contraction of the lock tongue.

2. Lubrication and maintenance to ensure smooth operation

Add 1-2 drops of specialized lubricating oil to the moving parts such as lock core, lock tongue, and follower every quarter to reduce friction and extend component life. Avoid using regular engine oil or cooking oil to prevent dust adhesion or metal corrosion.

3. Check the fastening to prevent loose components

Check if the fixing screws of the lock body are loose every six months, gently tighten them with a screwdriver to ensure a tight connection between the lock body and the door body. Focus on checking the alignment of the locking tongue plate and locking buckle plate. If there is any deviation, adjust the position of the door frame or locking buckle plate.

4. Avoid collisions and protect the integrity of the structure

Avoid forcefully dropping the door or hitting the lock body during daily use to prevent deformation of components such as the lock tongue and bolt. If the lock tongue is found to be inflexible, it should be immediately stopped from use and professional personnel should be contacted for maintenance. Do not disassemble it by yourself.

5. Moisture proof treatment to adapt to bathroom environment

When the bathroom ventilation is poor, a dehumidification box can be placed around the lock body to reduce air humidity. For bathrooms that have not been used for a long time, it is recommended to regularly open the door lock to prevent internal parts from rusting due to moisture. If rust appears on the surface of the lock body, it needs to be treated with stainless steel cleaner and dried in a timely manner.
