The Cal-Royal SLAUTOFLW4 Wood Door Automatic Flush Bolt is a high-quality, fire-rated flush bolt set designed for securing inactive wood doors in commercial and institutional applications. This combination includes a self-latching top bolt and an automatic bottom flush bolt, both crafted from durable steel with stainless steel components for long-lasting performance. UL Listed for B, C, D, and E label wood composite core fire doors up to 8 feet in height, the SLAUTOFLW4 complies with UL10C and UBC 7-2-1997 standards. It features a 3/4" bolt throw, 1" x 8-1/2" faceplates, and a reversible, non-handed design for easy installation. The built-in override function prevents damage from misalignment, while the smooth cam and piston mechanism requires only 5 lbs of force to operate, meeting ADA requirements. Ideal for standard ANSI door preparations, this flush bolt set is available in multiple architectural finishes to complement any design aesthetic.
