Product Description

The NATIONAL MFG/SPECTRUM BRANDS HHI N166-001 is a 6-inch lockable security bolt finished in black, designed for securing barn doors, gates, and shed doors in exterior applications. The bolt accepts a standard padlock, adding a second layer of protection beyond the bolt itself. A Weatherguard Protection coating resists corrosion and stands up to harsh outdoor conditions. Mounting hardware is included. This hardware is installed by general contractors, fencing professionals, and experienced DIYers working on outbuildings, agricultural structures, and perimeter gates.

The N166-001 is suited for residential and light commercial exterior door and gate applications where a visible, padlock-compatible security bolt is required. Common installations include sliding barn doors, swing gates, and shed entry doors exposed to outdoor weather. The black finish blends with standard exterior hardware on painted or stained wood structures. Package quantity is 5 units per pack, making it practical for multi-door projects or contractor restocking.
