Detex DX3 Gray Triple Hinge Bolt Hinge Side Dead Bolt

Product Description

The DETEX DX3 GRAY is a triple hinge bolt set designed to provide supplementary security on the hinge side of a door. Hinge side locking dead bolts address a common vulnerability in door assemblies: an intruder forcing or removing the hinge pins can defeat a standard latch or lockset. These bolts install into the hinge side of the door frame and engage the door edge, creating a mechanical barrier that resists forced entry even if hinge pins are removed. The gray finish integrates cleanly with standard commercial and residential door hardware. Installation is straightforward for locksmiths, door hardware specialists, and security-conscious contractors.

This set suits applications where supplementary hinge-side protection is required beyond the primary lockset. Typical scenarios include commercial entry doors, hollow metal door frames, and residential exterior doors where enhanced forced-entry resistance is a priority. The triple-bolt configuration distributes resistance across three points along the hinge stile, improving overall door frame integrity under lateral load or pry attack.

Key Features

• Triple dead bolt configuration provides three-point hinge-side engagement
• Supplements primary lockset for added forced-entry resistance
• Designed to retain door even if hinge pins are removed or compromised
• Gray finish for low-profile integration with standard door hardware
• Suitable for both residential and light commercial door assemblies

Compatibility

Designed as an OEM-style supplementary hinge-side security upgrade for standard swinging door assemblies where hinge-side reinforcement is required.

Installation Notes

Installation is typically performed by a licensed locksmith or experienced door hardware technician. The door should be secured in the open position and all associated locking hardware should be in the unlocked state before drilling or mortising. Follow local building and fire codes, as supplementary security hardware on egress doors may be subject to IBC or local AHJ requirements. Verify bolt alignment with the door frame strike before final fastening to ensure smooth engagement and full bolt throw.
