PROPER MOUNTING SECURITY
In concrete filled headers, the blind nuts function normally but a problem can occur in pulling
the hook up wires as it is difficult to run a wireway in concrete. The center of the bracket for the
model 62 and model 82 versions forms a splice chamber if it's difficult to pull the wires back into
the header. The model 32 version has a slot to bring the wire into the header because of the
narrowness of the lock. Alternately the wires may be pulled through the edge of the bracket by
drilling a hole if it's impractical to drill the concrete. A final technique for concrete headers is the
use of Securitron's "G" version Magnalock (not available in the 32 or 34 series) which
incorporates a 1/2" female/-3/4" male universal threaded conduit fitting. The conduit fitting is
placed on the end of the magnet body, and the problem of pulling wires into concrete is
bypassed as the wires may be run in pipe in a surface mount configuration. The mounting holes
on "G" locks are counter-bored from both sides to make the lock non-handed.
With a wooden frame, long wood screws are used to mount the Magnalock. The screws must
penetrate as deeply as possible through the stop and frame into the header to yield adequate
mounting strength. The Magnalock mounts to the bracket via machine screws and the bracket
permits wood screws (furnished) to penetrate deeply into the header (see Figure 12)
2.6 MOUNTING THE MAGNALOCK ON EXTERIOR GATES
A popular application for the Magnalock is to secure motorized or manual exterior gates. The
Magnalock has several benefits in this application. Gates tend not to be precisely fitted so
electric bolts suffer from alignment failures. The Magnalock is designed to be self aligning and
tolerates considerable inconsistency in the gate closed position as regards upward/downward
