These specially designed sash locks are loaded with “hidden features”! The clean, low profile design of these locks requires a stop thickness of only .625” (15.8 mm) while still providing a full .250” (6.3 mm) screen rabbet. When properly installed, the revolving cam locking mechanism provides a .625” (15.8 mm) draw-in at the sash. Using a #31358 Keeper, when properly installed, this produces a minimum forced entry resistance capability of 250 lbs. per lock (200 lbs. minimum per lock using a #31344 Keeper). 

An added bonus is that the non-handed design helps hold down expensive inventories. Wherever architect requirements, or purchaser’s preference, call for tandem sash lock operation, Order Part #16.19 sash lock readily adaptable to a tandem configuration. A single rabbet cut into the lock side of the jamb is all that is necessary for tie bar installation. Rabbet and tie bars are completely concealed by the application of the customary stop.
