Deltana S45BBU26D Square Hinge Heavy Duty Ball Bearing

Product Description

The DELTANA S45BBU26D is a heavy-duty square door hinge finished in satin chrome and built for demanding commercial and residential door applications. Measuring 4.5 inches by 4.5 inches, this full-mortise hinge features precision ball bearings that reduce pivot friction and support consistent swing performance over high-cycle use. Sold as a pair, it is suited for installation by carpenters, millwork contractors, and door hardware specialists working on interior or exterior door frames that require a durable, corrosion-resistant hinge with a clean architectural appearance.

This hinge is appropriate for heavy interior and exterior doors in both residential and light commercial settings. The satin chrome finish provides a brushed, low-gloss look that complements contemporary and transitional hardware finishes. Ball bearing construction makes it a reliable choice for high-traffic doorways where a standard plain-bearing hinge would wear prematurely. It is commonly installed on wood or metal door frames in office, hospitality, and multi-family residential projects.

Key Features

• 4.5 inch by 4.5 inch square corner profile for full-mortise installation
• Ball bearing pivot mechanism reduces friction and wear under heavy use
• Satin chrome finish resists tarnish and suits a wide range of architectural hardware sets
• Heavy-duty construction rated for high-cycle, high-traffic door applications
• Sold as a pair to supply a standard single-door installation point

Compatibility

Designed as an OEM-style replacement or new-installation hinge for full-mortise door applications requiring a 4.5 inch square heavy-duty ball bearing hinge in a satin chrome finish.

Installation Notes

Installation is typically performed by a licensed carpenter or door hardware installer using a chisel, router, or hinge mortising jig to recess the leaf flush with the door edge and jamb. Power down any electric strike or access control hardware associated with the door frame before beginning work. Follow applicable building codes for door hardware in commercial occupancies, including fire-rated door assembly requirements where applicable. Do not over-drive fasteners, as this can distort the hinge leaf and affect door alignment.
