Product Overview

American Maytag AD30# STACK and 535, ADG 32 series
TRI-GARD LOCKS-The Tri-Gard lock is similar to the Duo and the Greenwald Sentinel, and cost very little more than the Nova. This is a fourteen wafer lock which is Triple Bitted. That is, the key moves wafers from three different levels. This provides excellent resistance to picking. The key-bow is generous and the key itself is thicker than most keys, which allows the removal of coin boxes with less strain.
