The Steel Hawk 4300 from Adams Rite Manufacturing Co. allows electric locks to be installed in any aluminum entrance door, even those not electrified. Its two-way design allows it to adapt to any door without modifications, and the Steel Hawk retrofits to 4900/4500/4700 Adams Rite deadlatches (using the same strike). It is compatible with existing handles, paddles, and levers, adapts to 12V, 16V, and 24V DC, and exceeds ANSI/BHMA Grade 1 requirements. A locked-unlocked status monitor switch is optional, and the latch is made of steel with stainless steel latchbolts. steel-hawk.com
