Fire Rated Shearlocks

Our range of fire rated shearlocks provides concealed electromagnetic locking for suitable fire-rated door applications where a discreet installation and high holding force are required.

Fire rated shearlocks use magnetic force combined with a mechanical shear action to secure the door. When energised and correctly aligned, the armature is drawn into the lock body and held in position, creating a strong locking connection while allowing the hardware to remain concealed within the door and frame.

These locks are intended for use on suitable fire-rated door assemblies where the complete door set, lock, fixing method and associated hardware meet the relevant certification and installation requirements.

Available options may include monitored and unmonitored models, different holding forces, narrow-profile versions and models suitable for single-action or double-action door arrangements.

Typical applications include:

  • Fire-rated access control doors
  • Commercial buildings
  • Office environments
  • Educational facilities
  • Healthcare buildings
  • Public buildings
  • Residential developments
  • Restricted access areas
  • Timber doors
  • Metal doors
  • Aluminium doors
  • Specialist fire-rated door applications

Fire rated shearlocks can be integrated with compatible access control systems, keypads, proximity readers, power supplies, timers, relays, exit devices and emergency door release units.

Correct installation and alignment are especially important with shearlocks. Please check the door type, frame construction, operating voltage, holding force, monitoring requirements, mounting position, installation tolerances and fire test evidence before ordering.

Where a shearlock is installed on a fire-rated door, the complete door assembly, lock, fixings and associated hardware must be suitable for the specific application and installed in accordance with the relevant certification and manufacturer instructions.
