Shootbolt handle

Our shootbolt handles are robustly designed, whilst also offering great aesthetics. For security assurances, they drive a shootbolt from the traffic door which is designed to withstand forced entry.

Butt hinges

Though Caldwell can offer bespoke hardware creation, our primary focus for door hardware is in the supply of manufacture of butt hinges.

Also available for casement windows, we can manufacture and supply butt hinge designs based on frame specifications, whilst also taking into account different load bearing requirements to ascertain the optimum hinge location. Our butt hinges are extruded in aluminium, and are fixed with stainless steel pivot pins for consistency in their finish and improved strength and durability. For lower levels of maintenance and ease of operation, Caldwell butt hinges also feature self-lubricating nylon bushes.
