Product Overview

Adams Rite is known around the world for durable and reliable door hardware. Our latest line of premium electric strikes, the UltraLine 7400 series, casts that reputation in solid steel. UltraLine Strikes feature an adjustable split-jaw design, and can operate with up to 35lbs. of door “preload” that can disable other electric strikes.

Models

• 74R1 Electric Strike is designed for rim exit devices with 3/4 [19.1 mm] Pullman latchbolts. For use in aluminum, hollow metal or wood applications.

Open electrically under 25 lbs [11.3 kg] of preload. Preload is pressure exerted on doors by air conditioning systems, warping or misaligned hardware which can disable common electric strikes.

Function

These non-handed strikes feature an ultra-compact design and adjustable stainless steel keepers with over 1,500 lbs [680.4 kg] of holding force in fail secure mode. The strikes release electrically with up to 25 lbs of door preload. Single solenoid operates on 12/16/24 VDC power. Provides electrical remote control, allowing door to open without actuation of the exit device.
