Hager Hinge 12794124 Full Mortise Plain Bearing Hinge 4.5x4.5

Product Description

The HAGER HINGE 12794124 is a full mortise, five-knuckle plain bearing door hinge in a standard weight configuration with a satin brass finish. Designed for commercial and residential door applications, this hinge measures 4.5 inches by 4.5 inches and weighs 2 pounds per unit. The five-knuckle design provides a clean, traditional profile while the plain bearing construction suits standard-frequency swing doors that do not require heavy-duty or anti-friction bearings. Installers in commercial construction, door hardware distribution, and locksmith trades select this hinge for its reliable mortise-style fit and corrosion-resistant satin brass finish.

This hinge is suited for full mortise installation on interior and light-duty exterior door applications where a standard weight hinge meets the load and frequency requirements. It ships as a single unit and is appropriate for door frames requiring a 4.5-inch by 4.5-inch hinge cutout. Typical installations include office doors, hotel corridor doors, and light commercial entryways. The satin brass finish coordinates with matching door hardware sets in commercial and residential projects alike.

Installation Notes

Full mortise hinges are installed by licensed door hardware technicians or carpenters who mortise the hinge leaf into both the door edge and the door frame. Power down any access-control or electric-strike hardware associated with the door assembly before beginning work. Use a sharp chisel or router to achieve a clean, flush mortise pocket that matches the hinge leaf dimensions precisely. Fastener torque and door prep dimensions should comply with the door and frame manufacturer specifications and applicable building codes.
