Deltana SS44R5BU32D-S 4x4 Radius Security Hinge Satin Stainless

Product Description

The DELTANA SS44R5BU32D-S is a 4-inch x 4-inch radius corner door hinge with a 5/8-inch radius, two ball bearings (2BB), and a security feature designed to resist forced entry. Finished in satin stainless steel, this hinge is built for high-traffic or security-sensitive door installations where corrosion resistance and long-term durability are required. Sold as a pair, it is appropriate for commercial and residential applications where a clean, brushed stainless aesthetic is specified. Door hardware installers, finish carpenters, and commercial contractors are the primary trades working with this product.

This hinge is suited for interior and exterior door installations requiring a radius corner profile and enhanced security retention. The satin stainless steel finish performs well in high-humidity environments such as restrooms, entryways, and coastal construction where standard steel hardware would corrode prematurely. The 2BB (two ball bearing) construction reduces pivot friction on heavy or frequently cycled doors. Typical applications include commercial office entry doors, institutional facilities, and residential exterior doors where code or spec calls for a security hinge.

Key Features

• 4-inch x 4-inch leaf size with 5/8-inch radius corners for a standard architectural profile

Compatibility

Designed as an OEM-style replacement or new-construction hinge for standard 4-inch x 4-inch hinge prep mortises on commercial and residential doors.

Installation Notes

Installation is performed by door hardware installers, finish carpenters, or commercial contractors. Power down any electric strike or access control hardware tied to the door circuit before beginning work. Mortise dimensions should be verified against the door and frame prep before installation. Fastener seating should be flush to prevent binding; do not overdrive screws into the hinge leaf countersinks.
