Deltana S44HDBB3 Square Hinge Heavy Duty Ball Bearing 4x4

Product Description

The DELTANA S44HDBB3 is a 4-inch x 4-inch square door hinge built for heavy-duty applications where standard hinges fall short. It ships as a pair and features ball bearing construction for smooth, low-friction operation over years of repeated cycling. The hinge is finished in bright brass, making it suitable for installations where both performance and appearance matter. This is an architectural-grade product intended for doors that see frequent use or carry significant weight. Licensed contractors and finish carpenters working on commercial or high-end residential projects are the primary installers of this hardware.

The S44HDBB3 is appropriate for interior and exterior door applications where a heavy-duty, ball-bearing hinge is specified. Its square corner profile and bright brass finish align with traditional and transitional architectural styles. The 4-inch leaf size suits standard to oversized door panels in residential and light commercial construction. Each unit sold is a pair, making it straightforward to order by door count on larger projects.

Installation Notes

Installation is typically performed by a licensed finish carpenter, door installer, or general contractor. Remove the door from the frame before hinge replacement to ensure safe, accurate mortise work. Use a sharp chisel and hinge template to achieve a flush mortise depth that matches the hinge leaf thickness. Verify door weight and frequency-of-use requirements against the hinge rating before finalizing the installation.
