Don-Jo HWBB84545 Heavy Weight Ball Bearing Hinge | 4-1/2" x 4-1/2" | 626 Satin Chrome (US26D)
The Don-Jo HWBB84545 is a Heavy Weight Ball Bearing Hinge built for heavy doors demanding a full mortise butt hinge with the durability to match. Sized at 4-1/2" x 4-1/2" and formed from brass at a 0.18-gauge thickness, this five-knuckle hinge delivers the structural integrity commercial specifiers require on high-traffic and heavy-duty door applications. The 626 Satin Chrome (US26D) finish provides a clean, professional appearance suited to institutional, commercial, and municipal openings. Conforming to ANSI A2111, the HWBB84545 meets the template and performance standards that architects and door hardware consultants specify on commercial projects. Non-removable pins (NRP) ship as standard on every unit — no upcharge, no special order required.
Heavy-Duty Ball Bearing Performance
The ball bearing design of the HWBB84545 reduces friction and wear on heavy door applications where standard hinges fall short.
- Ball Bearing Construction: Ball bearing hinge technology minimizes pivot-point friction, extending service life on heavy commercial doors subjected to constant cycling.
- 0.18-Gauge Brass Leaf: Heavier gauge material than standard-weight hinges delivers the structural strength required for heavy door applications in high-frequency openings.
- For Heavy Doors: Factory-designated for heavy-weight door hardware schedules, making specification and submittal straightforward on demanding commercial projects.
Non-Removable Pin — Standard, Not an Option
Every Don-Jo HWBB84545 ships with a non-removable pin (NRP) as a factory-standard feature on all heavy-weight ball bearing hinges.
- Security by Default: The non-removable pin prevents hinge-side forced-entry attempts, meeting the security expectations of commercial door hardware specifications without an added line-item cost.
- No Special Order Required: NRP is included on every HWBB unit — simplifying procurement and ensuring your hardware schedule is fulfilled as specified from the factory.
ANSI A2111 Template Compliance
The HWBB84545 conforms to ANSI A2111, the full mortise butt hinge template standard recognized across commercial door hardware schedules.
- ANSI Template: ANSI A2111 compliance ensures the hinge aligns with standard door and frame mortise prep, simplifying installation and field verification on commercial openings.
- Cross-Reference Ready: The 4-1/2" x 4-1/2" template footprint is dimensionally compatible for fit comparison with other ANSI A2111 full mortise heavy-weight hinges from major manufacturers.
