Product Info

Door bolts with Armor-Coat have a UV and rust resistant protective finish making them suitable for internal or external use. These black knob bolts have a unique ball bearing system which allows them to keep their positive movement, unlike spring versions which lose tension over a period of time.

These door bolts are available in 4 inch and 6 inch sizes, with an option of cranked and straight styles.

Cranked Bolts: Also known as offset or necked bolts. These are designed for offset levels. Supplied with a mortice plate.
