Aluminum Glass Mortise Lock - Installation Jig (AGML-JIG)

AGML-JIG

Designed for use by professionals for the installation of latches and swing bolts on 1 ¾” thick aluminum and glass doors. This reversible jig is factory set so that the backset is gauged from the center of the door edge and will work with 1 1/8” or 31/32” backset locks by simply flipping the jig.

It secures to the door using self-drilling self-tapping screws so it can't slip like other jigs. Screw holes are where the AR-style universal mounting tab screws go after the jig is removed from the door.

This is designed to be used with a router equipped with a 1/2" guide bushing and a 1/4" down cutting spiral bit. Bits, guides, and other accessories are available from Cothron's.

The handle of the Pro-Installer has a raised ridge on the inside that sits against the door, ensuring the backset is gauged from the center of the door and not affected by the bevel. 

The scale etched into the handle makes it easy to position the jig above the existing lock by simply centering the latch of the existing lock at the desired measurement.
​
​
​The cross bore guide plates are held in place by magnets, making it easy to change backset by flipping them around from 2-3/8”  to 2-3/4”.
​

All of the parts, including the guides, are easily replaced if lost or damaged.
