The Cal-Royal SLAUTOFLM3 Metal Door Automatic Flush Bolt is a premium, fire-rated hardware solution engineered for securing inactive metal doors in commercial and institutional settings. This flush bolt set includes a self-latching top bolt and an automatic bottom bolt, providing full compliance with UL10C and UBC 7-2-1997 standards for A through E label fire doors up to 8 feet in height. Designed for durability and ease of use, it features a reversible, non-handed steel body with stainless steel components, a thermal lock that activates during fire conditions, and a smooth cam and piston mechanism that meets ADA requirements with only 5 lbs of actuation force. The 3/4" bolt throw and 3/4" vertical adjustment allow for flexible installation without removing the door, while the override feature prevents damage from misalignment. Compatible with standard ANSI door preparations and available in multiple architectural finishes, the SLAUTOFLM3 delivers reliable, code-compliant security.
