How it connects

Holes on the lid hinge ears align with corresponding holes or bosses on the base body. Cylindrical hinge or clevis pins are inserted through both aligned tabs and secured with R-clips, cotter pins, or retainers.

Male and female halves

Interlocking bracket lugs/clevis ears mating via inserted genderless cylindrical hinge pins.

Usually connects to

  • hood / grill lid hinge bracket
  • cookbox / base hinge bracket

Common sizes

  • Pin diameters typically 1/4 in (6.35 mm) to 3/8 in (9.5 mm); hinge pair spacing commonly 300 mm to 900 mm depending on grill/lid width.

Where it is used

Variations

  • clevis pin with hairpin cotter (R-clip)
  • shoulder screw / pivot bolt hinge
  • grooved pin with E-clip / retaining ring

How to recognise it

Recognised by two distinct bracket mounting points along the rear top edge of a grill or enclosure, featuring aligned circular eyelets through which smooth round pins with cotter/hitch clips or retaining rings pass.

Often confused with

Confused withHow to tell them apart
Continuous / piano hingeContinuous hinges span the entire length with an integrated rolled barrel, whereas lid hinge pairs consist of two separate spaced pivot points.
Butt hingeStandard butt hinges have fixed overlapping leaves screwed to flat surfaces rather than integrated cast/sheet metal lugs accepting loose retention pins.

Good to know

In outdoor grills and smokers, this pair of pinned hinge points allows tool-less lid removal for maintenance or cleaning by pulling the retaining hairpins.
