BB5210 5 X 4 1/2" HEAVY WEIGHT 4 BALL BEARING HINGE
BB5210 5-Inch x 4-1/2-Inch Heavy-Weight Four Ball Bearing Hinge
Usually Ships: 1-3 Business Days
Our BB5210 Heavy-Weight Four Ball Bearing Hinge provides a 5-inch height x 4-1/2-inch open width in a full-mortise template format. Its .190-inch leaf thickness and four-bearing arrangement suit commercial projects specifying heavy-weight bearing hinges for heavier doors or frequent operation. Match the hinge set to the actual door, frame, closer, and hardware schedule before ordering.
Practical Uses
- Entrance and corridor doors: Use where the project calls for heavy-weight ball bearing hinges.
- Frequently operated openings: Coordinate bearing selection with traffic, door weight, and closer requirements.
- Replacement work: Compare the open dimensions, thickness, screw pattern, and mortise preparation before fitting.
Everyday example: A facilities team replaces worn hinges on a busy corridor door. The installer checks the 5-inch hinge height, 4-1/2-inch open width, .190-inch recess depth, and attachment before choosing BB5210. After installing the complete set, the team checks even door gaps, free swing, closing, and latching rather than assuming a heavier hinge alone corrects sagging or a damaged frame.
Size and Fit
Open width: The 4-1/2-inch dimension is measured across the open leaves, not across a single leaf. Check both height and width against the actual preparation.
Full mortise: One leaf is recessed into the door and the other into the frame. Both must seat correctly. The .190-inch leaf is not automatically interchangeable with a thinner hinge without checking the recess depth and operating gaps.
Available Finishes
- US26D Satin Chrome

Choose the required finish in the selector. Confirm the supplied base material when environmental exposure or a project requirement makes it critical. A finish choice alone does not establish a marine-grade or non-removable-pin configuration.
Installation Guidance
- Review the door: Check height, width, weight, construction, operating frequency, and closer forces.
- Confirm preparation: Compare the actual hinge and exact template with the door and frame before drilling or machining.
- Support the leaf: Secure the door during removal and installation.
- Use suitable attachment: Verify sound backing and adequate screw engagement. The exact template references eight #12 x 1-1/4-inch wood screws and eight #12-24 x 1/2-inch machine screws; select the appropriate type for the preparation.
- Align and test: Keep hinge axes aligned and check free swing, clearances, closing, and latching after fitting.

Maintenance and Project Coordination
Check attachment and alignment periodically. Use cleaning and lubrication methods appropriate for the supplied finish and bearings. Investigate continuing sagging or binding across the complete opening, including door construction, frame condition, and closer adjustment.
Confirm the required hinge quantity and any specified NRP option before ordering. NRP uses a retaining set screw to help prevent pin removal while the door is closed. For rated openings, verify the exact supplied hinge and installation against the complete door assembly requirements rather than assuming a hinge alone establishes the rating.
