Hager Hinge BB1173 4.5x4.5 Half Surface Ball Bearing Hinge

Product Description

The HAGER HINGE BB1173 is a half surface, standard weight ball bearing hinge designed for commercial door applications. It measures 4-1/2 inches x 4-1/2 inches and is constructed from steel with a satin chrome finish. The hinge features two ball bearings for smooth, low-friction operation and a non-rising removable pin with button tip and plug for easy door removal without specialized tools. The beveled surface leaf and reversible design add installation flexibility. This hinge is typically installed by commercial door hardware technicians or general contractors on hollow metal or wood doors in light commercial and institutional settings.

This half surface hinge is suited for commercial interior door installations where one leaf mounts to the door face and the other to the door frame. The satin chrome finish is appropriate for environments requiring a clean, professional appearance. It falls within the Hager Commercial Hinge Series and is sold individually per unit. The reversible design accommodates both left-hand and right-hand door configurations without stocking separate SKUs.

Installation Notes

Installation is typically performed by a licensed door hardware technician or qualified contractor. Remove the door from service and ensure the door frame is structurally sound before mounting. Use fasteners appropriate for the substrate material, whether hollow metal, solid wood, or composite. Verify local building codes for required hinge count per door based on door height and weight before installation.
