Casey Cohorst from Allegion sent me this Fixed-it Friday photo of an electromagnetic lock that was recently installed on a current project. Typically, mag-locks are mounted on the push side of the opening under the frame head, with the steel armature mounted on the face of the door. When the mag-lock must be mounted on the pull side of the opening, top-jamb brackets are used to change the position of the armature.
I’m not a huge fan of the TJ mount (it’s not the most beautiful application), but especially with the particleboard that was added to this installation because of the frame condition. This will surely weaken the holding force of the mag-lock.
