The 942NH is U.L. listed for 1½ hrs fire rating on wood and composite doors measuring up to 1219mm wide x 2743mm high. It is used on the inactive leaf of a pair of timber doors, and fits the standard ANSI preparation. The units are supplied in pairs, consisting of a bolt for the top of the door and another bolt for the bottom of the door. The unit is fully automatic and requires no power or electricity. When the active door is closed, the bolts project into the frame, securing the inactive leaf. When the active door is opened, the top and bottom bolts in the inactive leaf are automatically retracted for easy egress. Reversible, non-handed.
