GRI  120T12B  Recessed Switch Set, Closed Loop,   3/8" M-5 Magnet W/ 3/4" Switch  Brown -  SOLD IN LOTS OF 10 ONLY GRI 120T12W Recessed Switch Set, Closed Loop,  3/8" M-5 Magnet W/ 3/4" Switch, White - PLEASE ORDER IN MULTIPES OF 10 ONLY

The 120T/4473 requires that a 3/4" hole be drilled for the switch and 3/8" hole for the magnet. The 3/4" switch mounting is desirable since the extra wire and connections can be more easily inserted into the larger hole for concealment. Also, should the need arise for testing or replacement, it would be easy to pull the switch, extend the extra wire and access the original connections.

Installation is further enhanced by using a smaller 3/8" diameter magnet to avoid the need to center a larger hole in a 1" to 1 1/2" thick door or window. This will allow you to offset the magnet should it be required.

The 120T/4473 switch set was developed for and should only be used in openings with wooden or aluminum frames.
