Ives 5BB1412651 Ball Bearing Hinge 4.5x4.5 in Bright Chrome

Product Description

The IVES 5BB1412651 is a five-knuckle, ball-bearing, standard-weight door hinge finished in bright chrome. Ball-bearing knuckles reduce friction and wear under continuous use, making this hinge well suited for commercial and residential interior doors that see regular traffic. The hinge measures 4.5 inches by 4.5 inches, a standard full-mortise size accepted by most door prep cutouts in that dimension class. Installation is handled by finish carpenters, general contractors, or commercial door hardware technicians. The bright chrome finish provides a clean, polished appearance compatible with contemporary and traditional door hardware sets.

This hinge is appropriate for standard-weight interior door applications in both commercial and residential settings. It is sold individually and is typically used in pairs or sets of three depending on door height and weight requirements. The 4.5-inch leaf size suits commercial-grade hollow-metal or solid-wood door frames prepared to that specification. The bright chrome finish coordinates with matching IVES door trim, pulls, and protection plate products for a consistent hardware appearance across the opening.

Installation Notes

Installation is performed by finish carpenters, commercial door hardware installers, or qualified general contractors. Remove the door from the opening and ensure all hinge mortises are clean and square before seating the leaves. Follow local building codes and door manufacturer guidelines for hinge quantity per door based on door height, weight, and fire-rating requirements. Do not overtighten fasteners into hollow-core door stiles, as this can strip the substrate and compromise hinge pull-through resistance.
