Bolts and Flushbolts

Door Bolts & Flush Bolts for Commercial and Residential Doors

Door bolts play a critical role in securing inactive door leaves, improving safety, and maintaining code compliance in commercial buildings, schools, healthcare facilities, offices, hospitality properties, and residential projects. Whether you need an automatic flush bolt for a pair of fire-rated doors or a heavy-duty surface bolt for added security, choosing the correct bolt ensures reliable performance and long-term durability.

Automatic flush bolts are one of the most popular solutions for double-door openings. These systems automatically engage the top and bottom rods when the active door closes, securing the inactive leaf without requiring manual operation. Products such as the Rockwood 2842 and Rockwood 2942 Automatic Flush Bolt Sets are widely used in commercial applications where convenience and code compliance are important.

Manual flush bolts provide a simple and dependable solution for securing inactive doors. They are commonly installed on wood, hollow metal, and fire-rated doors where users manually extend or retract the bolt. Manual flush bolts are often selected for lower-traffic openings where automatic operation is not required.

Surface bolts mount directly to the face of the door and are commonly used on single doors, double doors, gates, storage rooms, and utility spaces. Heavy-duty options such as the Rockwood 580 and Rockwood 585 Surface Bolts offer exceptional durability and are available in multiple lengths and architectural finishes.

For fire-rated openings, fire bolts automatically activate when exposed to high temperatures, helping secure the inactive door leaf during a fire event. These specialized bolts are frequently specified for commercial buildings that require fire door assemblies to meet building and life-safety codes.

Choosing the Right Door Bolt

When selecting a door bolt, consider the door material, opening type, traffic level, and fire-rating requirements. Automatic flush bolts are ideal for frequently used pairs of doors, while manual flush bolts and surface bolts provide cost-effective solutions for lower-traffic applications. Fire-rated openings often require fire bolts or approved automatic flush bolt systems to meet code requirements.
