Surface Bolts
Surface Bolts offer a visible, heavy-duty security solution mounted directly onto the face of the door. Ideal for both commercial and industrial applications, these bolts provide extra staying power for oversized doors. Our selection includes heavy-duty steel and vandal-resistant designs that are easy to install, making them a top choice for perimeter security and high-traffic entrances.
Manual Flushbolts
Designed to be mortised into the edge of the door, Manual Flushbolts provide a clean, concealed look for the inactive leaf of a pair of doors. These are operated by a small flip-lever and are the standard choice for non-fire-rated openings where aesthetics are a priority. We stock various lengths and finishes to match your existing architectural hardware.
Automatic Flush Bolts
For fire-rated double doors, Automatic Flush Bolts are a life-safety requirement. These bolts automatically engage when the active door is closed and retract when it is opened, ensuring the building remains code-compliant without user intervention. Our inventory features high-performance options that provide smooth, hands-free operation and long-term reliability.
Thermal Pins
Thermal Pins (or fire bolts) are critical safety components used specifically on wood fire doors. When temperatures rise during a fire, the pin melts and locks the two door leaves together, preventing them from warping and allowing smoke or flames to pass through. These are often used with "Less Bottom Bolt" (LBR) exit devices to maintain fire ratings while keeping floors clear.
