What it is for

A door hinge is bought by length and thickness first, because the recess in the door edge is already cut: a 4-inch hinge will not drop into a 3-inch mortice, and a thin hinge in a deep mortice leaves the door hanging on the screws. Everything else — finish, ball bearings, fire rating — comes after the size.

Ball-bearing hinges are for heavy doors that are opened constantly, where the load should go into the bearing rather than the pin. Fire-rated hinges are thicker and matched to intumescent pads; on a fire door the pair has to be replaced as a set, not individually.

Specification detail

3 hinges, 4 in, Ball-Bearing, in carbon steel with a zinc plated finish, with matching screws. The knuckle is machined rather than rolled, so the pin stays tight after the door has been swung a few thousand times.

Before you order

Check the size and quantity against your own job first: most returns in this category come from ordering the wrong diameter, finish or pack size rather than from a fault. If you are unsure, send us a photo or a measurement and we will confirm which variant you need.
