Pick the holding force by door: 272 kg (600 lb) suits most office, shop and room doors; 500 kg (1,100 lb) is for main entrances, heavy doors and high-security rooms. Double doors need a double door lock or one lock per leaf. A magnetic lock opens when its power is cut, which is safe for fire exits, so give it a reliable power supply with battery backup. Add an exit button inside, and a bracket if the door opens inward or the frame is narrow. Ask us if you are not sure.

The lock body fixes to the door frame and the armature plate fixes to the door. On a door that opens inward, away from the lock side, or where the frame is too narrow, there is no flat place for them to meet. An L and Z bracket set solves this: the L-bracket holds the lock under the frame and the Z-bracket holds the armature plate on the door. Choose the bracket made for your lock model.

The exit button lets people inside open the door without a card, face or code. It connects to the exit input of the access controller or terminal, so the exit is also logged. A touchless button opens with a wave of the hand, which keeps it clean in clinics, offices and food areas.
