Deltana DSB4B15 Square Hinge Ball Bearing 4x4 Satin Nickel

Product Description

The DELTANA DSB4B15 is a 4-inch x 4-inch square door hinge with ball bearings and a satin nickel finish, built for commercial and residential door applications where smooth, durable operation is required. The ball bearing construction reduces friction at the knuckle, extending service life under frequent use. Sold as a pair, this hinge is appropriate for interior and exterior door installations where a clean, square-corner profile is specified. Licensed carpenters, door and hardware installers, and general contractors are the primary tradespeople who specify and install this product.

This hinge suits standard door installations in residential and light commercial construction. The satin nickel finish coordinates with common modern and transitional hardware palettes. The square corner profile is a common requirement in commercial-grade door framing specifications and is compatible with standard door prep mortise cuts. Each sales unit is one pair, making it straightforward to order by door count.
