What does the bolt number mean?

The size of the body and pin. The larger the number, the thicker the bolt and the heavier the leaf it can hold.

Where is a spring-loaded wrought iron bolt used?

On metal joinery, garden and wrought iron gates. The spring mechanism latches the leaf quickly, and lengths run from 100 to 600 mm.

Can a bolt replace a lock?

No. A bolt holds the leaf shut but cannot be locked with a key; on doors reachable from outside it should be paired with a padlock or a mortise lock.

Which bolts suit outdoor use?

Galvanised or properly coated metal joinery bolts and brass bolts last longest outdoors; uncoated steel bolts rust wherever they get wet.

Sliding Bolts

A sliding bolt is the simplest way to hold a door or leaf shut without a key. This page covers the types and how to read size and length. The catalogue holds 20 models.

Types and sizing

The barrel bolt is the classic surface-mounted bolt, sized by number; the larger the number, the thicker the body and the pin. A spring-loaded wrought iron bolt latches the leaf quickly and is used on metal joinery and garden gates — lengths run from 100 to 600 mm.

Brass bolts suit interiors and visible positions; a thumb-turn bolt is practical on leaves opened often. Metal joinery bolts are fixed by welding or with screws.
