EN1634 Fire Rated Best Roller Bolt Mortise Locks with CE EN12209 for Commercial Building-DDML010

1.High Durability

This roller bolt mortise lock has passed BS EN12209 certification and has undergone 200000 cycles of durability testing, far exceeding industry standards. The lock tongue and lock core are made of SUS304 stainless steel, which has strong wear resistance and is suitable for commercial places with high-frequency use. The roller structure reduces door closing resistance and extends service life.

2.Strong fire prevention

According to EN1634 standard, provide 260 minute fire integrity. The lock body and panel are both designed with metal seals, which do not deform when exposed to high temperatures, ensuring the safety of emergency passages. The fire test covers parameters such as tongue extension and thermal insulation, which meet the fire safety requirements of public buildings.

3.corrosion resistance

Passed EN1670 certification and underwent a 240 hour salt spray resistance test. Surface treatment options include PVD, PB, or AC electroplating, suitable for high humidity environments. SUS304 material forest and strike plate prevent rust and are suitable for coastal areas or industrial sites.

4.Stable structure

The back distance of the lock body is 55mm, the distance between the holes is 72mm, and it is compatible with European standard door types. The diameter of the solid stainless steel deadbolt reaches 18mm, and its anti pry strength meets the DIN 18251 Grade 3 standard. Square or curved panels are compatible with modern door designs.

5.Smooth operation

The closing noise of the roller lock tongue is less than 40 decibels, and the opening and closing torque is less than 0.8N · m. The bearing structure reduces friction and does not require additional lubrication. The handle rotation angle is 90 °, which conforms to ergonomics, and the driving force is reduced by 30% compared to traditional locks.

6.Multiple adaptations

Provide 6 surface treatments including SSS, PSS, MB, etc., suitable for different decorative styles. The panel can be designed with square or rounded corners, with an installation thickness range of 35-55mm. It supports customized key systems and is compatible with existing access control systems.

7.high security

Deadbolt has an extended length of over 20mm and an impact resistance of 1500N. The lock core meets EN1303 standards and is resistant to drilling, prying, and technical opening. The roller lock tongue is linked with the deadbolt to enhance the overall door breaking ability.
