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 Architectural Hinges are 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. Standard hinges are only to be used in a non-rated unit.
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). NRP hinges should be used with outswing units. Reeb stocks the plain-bearing hinge in US3, US10B, US1, and US26D, while the plain-bearing NRP hinge is only stocked in US26D
Ball-Bearing Architectural Hinges
Ball-Bearing Architectural Hinges are a full mortise, square corner steel hinge with a steel pin. The hinge is UL rated and can be used as a fire hinge. In between the knuckles are areas with ball bearings inserted. This helps with the continual use and function of the hinge over time. Ball-bearing hinges are used with rated units that have a door closer.
