Deltana S45BBU15 Square Heavy Duty Ball Bearing Hinge

Product Description

The DELTANA S45BBU15 is a heavy-duty square door hinge with a ball bearing design, built for high-traffic or high-load door applications. Measuring 4.5 inches by 4.5 inches, this hinge is finished in satin nickel and sold as a pair. Ball bearings provide smooth, consistent swing motion and reduce wear over repeated cycles. Licensed contractors and finish carpenters install this hardware on commercial and residential doors where a heavier-duty hinge is specified. The satin nickel finish delivers a clean, low-sheen appearance suited to modern and transitional door frames.

This hinge is appropriate for heavy interior and exterior doors in residential and light commercial settings. The square corner profile suits doors with square-cut mortises. At 4.5 inches, it is a common specification for solid-core wood doors, steel doors, and heavy flush doors where standard 3.5-inch hinges are undersized. Installers typically use this size on 1.75-inch thick door slabs requiring additional bearing capacity.

Key Features

• 4.5 inches x 4.5 inches square hinge plate — fits standard heavy-duty door mortises
• Ball bearing construction for smooth, low-friction door operation
• Satin nickel finish for a clean, understated appearance
• Heavy-duty build rated for high-cycle or weighted door applications
• Sold as a pair to match standard multi-hinge door installations

Compatibility

Designed as an OEM-style replacement or new-installation hinge for heavy-duty residential and light commercial doors requiring a 4.5-inch square corner hinge with a satin nickel finish.

Installation Notes

Installation is typically performed by a finish carpenter or licensed contractor. Power down any associated door hardware systems, such as electric strikes or access control devices, before servicing the door. Use a sharp chisel and appropriate mortise template to ensure a flush, square seat for the hinge leaf. Verify door weight and swing frequency against hinge load ratings before final installation.
