UL 305 and UL 10C are two distinct UL certifications for commercial door hardware. UL 305 governs panic and fire exit hardware, ensuring doors can be opened quickly during an emergency evacuation. UL 10C certifies that fire-rated door assemblies—including their hardware—can withstand f Read More

A rim exit device mounts on the surface of the door and latches into a strike on the frame, making it faster and less expensive to install, while a mortise exit device is recessed into a pocket cut inside the door itself, offering a stronger, more tamper-resistant latch for high-security application Read More

Fire rated hinges must be ball bearing hinges because standard hinges lack the melting-point resistance, load capacity, and cycle durability that fire doors demand. A fire door typically weighs 40–50 kg for a 30-minute rated door, and door closers add significant mechanical wear on top of that weigh Read More

A deadbolt is a standalone, single-bolt lock installed in a drilled hole, making it ideal for residential entry doors, while a mortise lock is a multi-function unit embedded into a pocket cut into the door, offering integrated latch and deadbolt mechanisms suited for commercial-grade security.

An ANSI Grade 1 mortise lock is the highest-performing classification under the ANSI/BHMA A156.13 standard, built to survive 1,000,000 open-close cycles and withstand a 360-pound force test — making it the required specification for schools, hospitals, government buildings, and other high-traffic co Read More

A delayed egress exit device is a code-compliant locking system that holds a door locked for a brief, controlled period — typically 15 or 30 seconds — after someone pushes the panic bar, giving staff time to respond before the door releases. It is designed for openings that must balance life-safety Read More

A panic bar with mortise lock combines a panic exit device with a mortise lock body to let occupants exit freely during an emergency while still giving facility managers the ability to control and monitor access from the outside. This combination is standard practice on fire-rated commercial doors w Read More

A rim exit device mounts to the surface of the door and suits doors without a mortise lock pocket—such as glass doors, decorative doors, and lighter-traffic entries—while a mortise exit device is recessed into the door edge and delivers higher security, making it the better fit for hig Read More
