Overhead Door Lock Service

Overhead doors present unique security challenges. Unlike standard commercial doors with deadbolts and strike plates, overhead doors need specialized security hardware designed for the roll-up or sectional configuration. Wrong hardware doesn't work; right hardware provides good security for commercial loading docks, warehouses, and industrial buildings.

Common overhead door security: slide bolts for roll-up doors (engage into track at sides), chain locks for manually-operated doors, padlocks on hasps for simple hasp-and-padlock security, and interior deadbolts or drop bars for added security after hours. Each approach has strengths and limitations.

Overhead door types and appropriate security

Overhead doors come in several configurations, each requiring specific security hardware. Understanding the door type is first step in specifying security.

Roll-Up Doors (Coiling): Steel or aluminum slats roll up into a cylinder at the top of the opening. Common for warehouses, loading docks, and industrial applications. Security options:
• Slide bolts - horizontal bolts at the sides that engage into the frame or track when door is closed.

Preventing the door from being lifted.
• Hasp and padlock - simple hasp mounted to door and frame secured with padlock.
• Drop bar - horizontal bar spanning behind the closed door, engaging into brackets on each side. Very strong but less convenient for frequent operation.

Sectional Doors: Panels hinged together, traveling up and overhead on tracks. Common for residential garages and light commercial. Security options:
• Slide bolts - bolts into the track at the sides.
• T-handle locks - integrated lock in the door handle.
• Interior deadbolts - mounted to the door or tracks for interior security.

Chain Hoist Operated: Older manually-operated overhead doors using chain hoists. Chain lock on the hoist mechanism prevents unauthorized operation. Typically supplemented with slide bolts or padlocks.

Electric Operator Doors: Overhead doors with electric operators (LiftMaster, Chamberlain, Genie, etc.). Security through remote control, keypad access, or integration with access control systems. Physical locks still needed for after-hours backup.

Common Security Weaknesses:

Padlocks: Basic padlocks are easily cut with bolt cutters. Upgrade to shrouded shackle padlocks, disc-style padlocks, or high-security padlocks (Abloy, Abus, American Lock) that resist cutting and picking. Worth the upgrade for warehouse security.

Lift-Up Attack: Roll-up doors can sometimes be lifted from the bottom if slide bolts aren't engaged. Always engage bolts when leaving. Drop bars prevent lift attacks even if bolts aren't used.

Track Bypass: Clever attackers sometimes bypass door security by accessing the tracks or rollers rather than defeating locks. Ensure track brackets are secure and reinforced.

Hardware Failures: Slide bolt mechanisms wear over time. Chain locks become difficult to operate. Regular service keeps overhead door security functioning.

Don't wait for failure - preventive service is cheaper.

Integration with Building Security: Overhead door locks are one layer. Building alarm systems, perimeter sensors, and camera surveillance complement physical lock security. Combined approach is strongest.
