Door bolts with Armor-Coat® UV and rust resistant protective finish. These black knob bolts are from the Stonebridge Ironmongery collection. The bolts use a unique ball bearing system, rather than a spring, which allows them to keep their positive movement, unlike spring versions which lose tension over a period of time.
The door bolts are available in two sizes. Cranked bolts (also known as offset or necked) are supplied with a mortice plate. Straight bolts, designed for flush surfaces, are supplied with a receiver bridge.
Stonebridge Ironmongery offer premium door & window hardware collections. All items are designed and finished by hand in the Stonebridge Ironmongery Durham factory.
Armor-Coat® Advanced Hardware Finish is a unique finish, specifically developed to provide corrosion protection in all weathers. Independent testing has awarded this finish BS EN 1670:2007 Grade 5 - the highest anti-corrosion level for steel-based hardware in the industry. Compatible with Accoya® wood, the world's leading high technology long-life wood. See our blog article Ironmongery for Accoya Wood Doors & Windows.
