Commercial Hinges

Hinges are an integral part of the door system which help to open and close the door. Commercial hinges are typically 4-1/2″ x 4-1/2″ with a C-shaped screw pattern. The hinge function determines the additional benefits of each hinge.


Standard Architectural Hinges

Standard hinges are only to be used in a non-rated unit. NRP hinges should be used with outswing units.

The 5000 series is a full mortise, square corner steel hinge with a steel pin. The hinge is not-rated as a fire hinge, but can be used in commercial applications. It is available for an inswing door where the pin is removable (known as a plain-bearing hinge); it is also available for an outswing door where the pin is not removable (known as a non-removable pin or NRP hinge). Reeb stocks the plain-bearing hinge in US3, US10B, U1S, and US26D, while the plain-bearing NRP hinge is only stocked in US26D

Ball-Bearing Architectural Hinges
