Ives 5BB1HW412652NRP Heavy Weight Ball Bearing Hinge 4.5in Satin

Product Description

The IVES 5BB1HW412652NRP is a five-knuckle, heavy-weight ball bearing hinge designed for high-traffic commercial and institutional door applications. It features a non-removable pin (NRP) for added security, preventing hinge disassembly from the exposed side of the door. Finished in satin chrome, it suits architectural hardware specifications calling for a brushed, low-sheen appearance. The hinge measures 4.5 inches x 4.5 inches and weighs 1.4 pounds, making it appropriate for heavy door assemblies where durability and smooth operation under repeated cycling are required. Installation is performed by licensed door hardware technicians or finish carpenters working to commercial building specifications.

This hinge is suited for commercial, institutional, and heavy residential door installations where a full-mortise, heavy-weight hinge is specified. Typical applications include high-cycle entry doors, corridor doors, and stairwell doors in commercial buildings. The non-removable pin configuration is commonly specified for doors swinging outward or in any location where hinge-side security is a code or project requirement. The satin chrome finish coordinates with standard commercial architectural hardware finishes across door lever, pull, and lockset selections.

Installation Notes

Installation is typically performed by a qualified door hardware installer or finish carpenter. Power down any electrified hardware integrated into the door frame before beginning work. Full-mortise hinges require precise router or chisel mortising of both the door edge and the frame to achieve flush seating. Reference applicable building codes and hardware finish schedules for correct placement, quantity, and hinge type requirements on the project.
