Don-Jo HWBB85045 Heavy Weight Ball Bearing Hinge | 5" x 4-1/2" | 626 Satin Chrome
The Don-Jo HWBB85045 is a heavy weight ball bearing hinge built from brass at a 0.19 gauge, sized 5" x 4-1/2" to handle the demands of heavy commercial doors. Finished in 626 Satin Chrome (US26D), this full mortise butt hinge meets ANSI A2111 and ships with a non-removable pin (NRP) as standard — a factory-included feature on every HWBB series hinge, not an upcharge. Specified by architects and door hardware contractors for high-traffic openings where a standard-weight hinge is simply undersized, the HWBB85045 delivers the load capacity and security a heavy door demands.
Heavy-Duty Brass Construction for High-Load Openings
The 0.19-gauge brass body gives this hinge the mass and rigidity required for heavy door applications.
- Brass material: Corrosion-resistant and machinable, brass at 0.19 gauge supports the door weight cycles that would stress a lighter-gauge hinge leaf over time.
- Heavy door rating: Don-Jo designates the HWBB series specifically for heavy doors, making it the appropriate specification when door weight exceeds the capacity of a standard commercial hinge.
Ball Bearing Operation and Non-Removable Pin Security
Ball bearing knuckles reduce pivot friction and support smooth, consistent door swing cycle after cycle on high-frequency openings.
- Ball bearing design: Engineered for high-frequency, heavy-duty operation, the ball bearings distribute load evenly at the hinge barrel, reducing wear on both the hinge and door frame.
- NRP standard inclusion: All Don-Jo HWBB heavy weight ball bearing hinges ship with a non-removable pin as a factory standard — a critical security feature on outswing doors where the pin would otherwise be exposed to the exterior.
ANSI A2111 Compliance and Non-Handed Installation
The HWBB85045 conforms to ANSI A2111 for heavy weight hinges and installs without handing, simplifying field inventory and job-site distribution.
- ANSI A2111: Compliance with this heavy weight hinge standard confirms the hinge meets industry-recognized performance criteria, supporting specification on commercial and institutional projects.
- Non-handed: The non-handed design means a single SKU covers left-hand and right-hand openings — no need to specify handing at time of order.
- 626 Satin Chrome (US26D) finish: A durable, low-sheen chrome finish that coordinates with a wide range of commercial door hardware and remains a high-demand commercial finish for office, institutional, and municipal applications.
