FF: Mag-Lock TJ Mount

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.

    Looks as though it is held on with 2 strips of Velcro,

    But suggest aluminum block or tube and through bolted,

    Is it a labeled door ?

    Why do so many people feel the only way to Electrify an opening is either a mag lock or strike, when I go to those last.

    a consideration with magnets in the door frame is the required headroom clearance of 80 inches along an accessible route.

    If the door head is 80 inches and other than the closure offends that clearance it creates a violation

      Hi Curtis –

      The ICC has approved a change for the 2021 edition that will allow mag-locks to project 2 inches down into the minimum height if it receives final approval. There is an exception for 78 inches to door closers and overhead stops, and this exception will extend to mag-locks and automatic operators in the 2021 edition.

    Ah, however her in Massachusetts the Accessibly portion of the ICC code family is superseded by the Architectural Access Board Regulations and doe not offer that exception.

    • Lori says:

      Yes – that is true, even though the Mass State Building Code does include the exception. When is Massachusetts just going to standardize their accessibility standard with the rest of the US?? It would be so much easier!

      – Lori

    Remember Massachusetts is a Commonwealth one of 4, so that make us special and a place where a lot of things behave differently per the codes.
    AAB might get the revision to it’s code passed if they stayed out of private spaces and fell in line with the rest of the world.
