2.6 MOUNTING T HE MAGNALOCK ON EXTERI OR 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
alignmen t, side alig nment an d twisting . The Magnalock is al so full y sealed and waterproof so it
is generally unaffected by tough environments.
The drawings and descriptions which follow, show conceptual installation concepts for different
types of g ate sec ur ity ap p l ication s. Note t h at t h e mod el 62 an d mod el 82 are most common l y
used in gate installations. They have conduit fittings available (“G” option) while this is not
available on the model 32 or 34 Most gate instal lations also call for hig her levels of hold ing
force as gates are often large and poorl y fit tin g . It’s al so oft en th e case t h at an in tru d er is ab l e
to physical ly apply more force to defeat a g ate lock th an is th e case with (especially) an
outswing in g door wherein the intr u der can onl y pull on it. The model 32 or 34 however may be
used on certain gat es with succes s. A good example is a s lidin g g ate wher e the Magn et can
be mortised into a p ost again st which the gat e slides. Securitron also off ers the mod el 34R
Magnalock which is specifically designed for mortising (see catalog).
Because of th e wide variety of gates in existence, each in stallat ion has to be con sidered s p ecial
and normally, bracketry must be made up on site. The concept is to mount the magnet on a
fixed post and the strike plate to the swinging or sliding member of the gate. Position both
component s so that the strik e plate sl aps again st th e magnet face on cl osure. Usuall y, th e
"GF" version of the Magnalock is used for gates. "G" calls out a conduit fitting mounted on the
magnet end and "F" calls out mounting holes through the face (see Figure 5). The magnet
typicall y screws onto a b ack plate fas h ioned on sit e and the b ack plate is welded onto t he fixed
post.
