Deltana DSB55B3 5x5 Square Ball Bearing Hinge Bright Brass

Product Description

The DELTANA DSB55B3 is a 5-inch x 5-inch square ball bearing hinge finished in bright brass. Ball bearing construction reduces friction and wear at the pivot point, making this hinge suited for heavy or frequently cycled doors. The solid brass base material provides corrosion resistance and holds the bright brass finish over extended service life. This hinge is installed by carpenters, millwork contractors, and door hardware specialists working on commercial or high-end residential projects where a full-size, heavy-duty hinge is required.

The DSB55B3 is sized for larger door applications where standard 4-inch or 4.5-inch hinges are undersized. The 5-inch x 5-inch leaf dimensions provide increased load distribution across the door frame and door stile. Typical applications include solid-core wood doors, heavy entry doors, and institutional or commercial interior doors where smooth, long-term operation is expected. This hinge is sold as a pair.

Key Features

• 5-inch x 5-inch square leaf dimensions for heavy-door applications
• Ball bearing pivot for low-friction, long-cycle performance
• Bright brass finish over solid brass construction
• Sold as a pair (PR) for single-door installation
• Square corner profile for traditional and commercial door aesthetics

Compatibility

Designed as an OEM-style replacement or new-installation hinge for heavy residential and commercial doors requiring a 5-inch x 5-inch square ball bearing hinge in a bright brass finish.

Installation Notes

Installation is performed by qualified carpenters or door hardware installers using standard chisels, routers, and screw drivers to mortise the hinge leaf flush into the door and frame. Remove the door from the opening and ensure all hardware is de-energized or disengaged before beginning work on access-controlled or automatic doors. Follow local building codes for hinge quantity and placement based on door height and weight. Use fasteners of compatible material to avoid galvanic corrosion at the mounting points.
