One of our property management clients had a problem with the header-hidden hydraulic door-closers intermittently failing to adequately draw the doors closed far enough to engage the electromagnetic locks. A fairly common problem that involves changing the closers to “surface-mount” closers installed in a “parallel-arm” configuration.
|
A secondary problem involved someone having installed the electromagnetic locks on the doors and jambs in such a location as to conflict with the surface-mount hydraulic-closers. So we engaged B&R Machine to fabricate custom “drop-plates” for the closer-bodies on the doors. But even more critically…were the aluminum drop-blocks we had them fab for the parallel-arm mounting brackets that fasten to the header-jambs.
|
The overall effect was to drop the closer-arms enough to swing into their parallel positions BELOW the electromagnetic locks, resolving the conflict. As you can see, we painted them to match to closers. Jared & Nathaniel are shown here drilling holes for fasteners that will reinforce the aluminum-cover header-piece to which our “drop-blocks” are fastened.
