Certifire Stainless Steel Polymer Bearing Hinges (Grade 13)

This collection brings together Certifire-approved, fire-rated stainless steel butt hinges with radiused corners and a 3-knuckle polymer bearing design. Built for smoother operation and reduced friction, they’re a practical choice for higher-use doors where consistent movement and durability matter.

Across the range you’ll find Grade 13 hinges in two sizes: 102mm x 102mm x 3mm and 102mm x 76mm x 3mm.
