Bolts

Bolts

Bolts are essential door and gate hardware components used to secure openings in both residential and commercial settings. They provide a simple yet effective means of locking, latching, or holding doors and gates in a fixed position, either closed or open. At John Barnes Group, we supply a comprehensive range of bolts designed to suit a wide variety of applications, from light residential use to heavy-duty industrial security. Buy Bolts online today from the John Barnes online shop!

What Are Bolts?

A bolt is a sliding metal rod that engages with a strike plate, bracket, or socket to secure a door, gate, or panel. Operated manually, bolts are easy to install and available in multiple configurations to meet different security, accessibility, and durability requirements.

They are commonly used in conjunction with other locking devices or as a secondary layer of security.
