BB600 4-1/2 STANDARD WEIGHT BALL BEARING SWING CLEAR HINGE
BB600 4-1/2-Inch Standard-Weight Swing-Clear Ball Bearing Hinge
Usually Ships: 1-3 Business Days
Our BB600 Swing-Clear Hinge uses an offset arrangement to help move the open door leaf away from the passage at 90 degrees. This 4-1/2-inch, standard-weight, two ball bearing hinge has .134-inch leaf thickness, square corners, and full-mortise mounting. It is designed for non-beveled-edge doors; check the actual door and frame geometry before specifying the hinge set.
Practical Uses
- Commercial passageways: Evaluate swing-clear movement where the open leaf projects into the usable passage.
- Equipment and cart routes: Help reduce obstruction from the open door when compatible geometry allows.
- Replacement projects: Compare offset, leaf thickness, corner style, and hole pattern rather than assuming nominal height establishes interchangeability.
- Hardware renovations: Coordinate the listed finish with the rest of the opening.
Everyday example: A maintenance team wants a corridor door to leave more usable passage for supply carts. The installer verifies the door's non-beveled edge, available swing space, square-corner mortises, and .134-inch leaf preparation before selecting BB600. Once fitted, the team checks clearance with the door at 90 degrees and confirms that the closer, stop, and nearby trim accommodate the new swing path. The hinge changes the door's open position, not the frame width.
Fit and Operation
4-1/2-inch nominal size: Check the actual hinge footprint and offset against the correct template. A conventional hinge of similar height does not necessarily share the same geometry or attachment pattern.
Full-mortise installation: One leaf is recessed into the door edge and the other into the frame. Match the .134-inch leaf thickness to the recess depth and verify both leaves can seat correctly.
Square corners and non-beveled door edge: Confirm both features at the opening. Do not substitute for a rounded preparation or beveled-edge application without reviewing the required hinge model and preparation.
Clearance planning: Check jamb profile, wall clearance, door thickness, trim, seals, stops, and closer travel. Do not assume a fixed increase in passage width for every installation.
Available Finishes

Select the required finish in the product options. Confirm the exact supplied base material where exposure conditions or a project specification makes that distinction important.
Installation Guidance
- Review the complete application: Consider door height, width, weight, construction, operating frequency, and closer requirements.
- Verify the preparation: Compare the actual hinge and BB600 template with both door and frame before machining.
- Support the door: Secure it throughout removal and fitting and verify sound reinforcement or backing.
- Choose suitable attachment: Use fasteners appropriate for the actual preparation and check adequate engagement.
- Align the hinge set: Seat the leaves correctly and keep hinge axes aligned to avoid binding.
- Check the full operating cycle: Verify free swing, passage at the intended angle, door gaps, closer operation, and latching.
Problems It Helps Address
- The open leaf obstructs passage: Provides swing-clear geometry for a compatible opening.
- Replacement fit needs confirmation: Identifies the square-corner, .134-inch, full-mortise format and correct drawing.
- Hardware finishes need coordination: Offers four listed finish choices.

Care and Project Coordination
Inspect attachment, alignment, and clearance periodically. Use cleaning and lubrication methods appropriate for the supplied finish and bearings. Investigate continuing rubbing or binding across the complete opening, including closer and stop settings.
Confirm the required hinge quantity and any specified non-removable-pin option before ordering. Verify required passage dimensions and accessibility or rated-opening requirements for the actual installed assembly. A swing-clear hinge alone does not establish compliance.
