The conduit fitting is placed on the end of the magnet body, and the problem of pulling wires into concreteis 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 adequatemounting strength. The Magnalock mounts to the bracket via machine screws and the bracketpermits wood screws (furnished) to penetrate deeply into the header (see Figure 10) Rev.

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 andtolerates considerable inconsistency in the gate closed position as regards upward/downwardalignment, side alignment and twisting. The Magnalock is also fully sealed and waterproof so itis generally unaffected by tough environments. The drawings and descriptions which follow, show conceptual installation concepts for differenttypes of gate security applications. Note that the model 62 and model 82 are most commonly used in gate installations. They have conduit fittings available (“G” option) while this is not available on the model 32 or 34 Most gate installations also call for higher levels of holdingforce as gates are often large and poorly fitting. It’s also often the case that an intruder is able to physically apply more force to defeat a gate lock than is the case with (especially) an outswinging door wherein the intruder can only pull on it. The model 32 or 34 however may be used on certain gates with success. A good example is a sliding gate where the Magnet canbe mortised into a post against which the gate slides. Securitron also offers the model 34R Magnalock which is specifically designed for mortising (see catalog). Because of the wide variety of gates in existence, each installation has to be considered specialand normally, bracketry must be made up on site. The concept is to mount the magnet on afixed post and the strike plate to the swinging or sliding member of the gate. Position both components so that the strike plate slaps against the magnet face on closure. Usually, the "GF" version of the Magnalock is used for gates. "G" calls out a conduit fitting mounted on themagnet end and "F" calls out mounting holes through the face (see Figure 5). The magnettypically screws onto a back plate fashioned on site and the back plate is welded onto the fixed post. Rev. A.3, 5/00 Page- 11 A back plate or Securitron's Z bracket must also typically be provided for the strike plate. The strike plate cannot be directly welded to the gate as it will not be able to flex and selfalign. It must be screwed onto a surface with the washer stack used to provide flexibility. Note that if Securitron's Z bracket is used, it typically bolts to the gate rather than iswelded as it is aluminum. Read sections 2.3, 2.3.1, and 2.3.2 for additional general information on mounting.

A.3, 5/00 Page- 12 In the case of very tall and large gates, a levering problem can exist. By this we mean that anintruder may be able to flex the gate enough to take up the slack in the strike mounting screwand then lever off the strike plate. If the installer or user determines that this may happen, asingle Magnalock will not provide adequate security and two must be used, typically at the topand bottom of the gate. Figure 11 (above) shows preferred special techniques for Magnalock mounting on 3 types of gates. The first drawing shows a single swinging gate. The general technique follows the principles discussed above but the use of Securitron's Z bracket which creates a neat installation is also shown. Note that in some cases, the post which mounts the magnet is hollow. It is possible to use the "F" version (without conduit fitting) and pull the wires throught...
