Ives 5BB1HW412630NRP Heavy Weight Ball Bearing Hinge 4.5in

Product Description

The IVES 5BB1HW412630NRP is a heavy-weight, five-knuckle ball bearing hinge finished in satin stainless steel. It measures 4.5 inches by 4.5 inches and is built for high-cycle door applications where standard-weight hinges would wear prematurely. The ball bearing knuckle design reduces friction and supports smooth, consistent door operation under load. At 1.3 pounds per leaf, this hinge is suited for solid wood and hollow metal doors in commercial and institutional settings where durability and finish consistency are required. Licensed contractors and finish carpenters install this hardware as part of a complete door prep package.

This hinge is appropriate for heavy interior and exterior doors in commercial buildings, schools, hospitals, office buildings, and multi-family residential construction. It is typically specified on doors requiring a corrosion-resistant architectural finish that coordinates with other satin stainless hardware on the opening. The satin stainless steel finish is well suited to high-traffic or high-humidity environments where finish longevity matters. Installation is performed by commercial door and hardware installers or finish carpenters working to project hardware schedules.
