Product Description

The EMTEK 91034US4 is a pair of residential duty steel hinges finished in Satin Brass. Each hinge measures 4 inches x 4 inches with a 5/8-inch radius corner, making it a standard fit for interior and light-duty exterior door applications. The Satin Brass finish provides a warm, understated tone suited to a range of door hardware styles. Sold as a pair, this product is installed by finish carpenters, general contractors, and experienced DIYers working on residential door projects. The steel construction delivers reliable cycle performance for standard passage and closet doors in residential settings.

These hinges are intended for residential door installations where a 4 inches x 4 inches full-mortise hinge is the specified size. Typical applications include interior passage doors, bedroom and hallway doors, and light-duty exterior doors in single-family or multi-unit residential construction. The 5/8-inch radius corner profile is one of the most common corner styles in residential door framing, fitting standard mortise cutouts without additional modification. The Satin Brass finish coordinates with a broad range of knobs, levers, and rosettes for a cohesive hardware scheme.

Installation Notes

Installation is performed by finish carpenters or general contractors using standard mortise chisels, a drill, and wood screws appropriate for the door and frame material. Power down any electric strike or access control circuit before working on an electrified door frame. Align the hinge leaf flush with the mortise surface before fastening to prevent binding. Follow local building codes for minimum hinge count and placement on fire-rated door assemblies.
