Don-Jo HWBB95045 Heavy Weight Ball Bearing Hinge | 5" x 4-1/2" | 630 Satin Stainless (US32D)
The Don-Jo HWBB95045 is a Heavy Weight Ball Bearing Hinge engineered for heavy doors that demand a full-mortise, 5-knuckle butt hinge built to ANSI A5111 standards. Manufactured from stainless steel at a robust 0.19 gauge, this 5" x 4-1/2" hinge delivers the structural integrity and corrosion resistance required by commercial door hardware specifiers working on high-traffic or high-cycle applications. The 630 satin stainless (US32D) finish provides a clean, low-maintenance appearance well-suited to institutional, healthcare, and commercial building environments where long-term durability and finish consistency are non-negotiable.
Stainless Steel Construction for Demanding Applications
The stainless steel body at 0.19 gauge makes the HWBB95045 one of the heavier-duty butt hinges in the Don-Jo commercial hinge line.
- Heavy-gauge body: The 0.19 gauge stainless steel leaf construction handles the load and cycle demands of heavy commercial doors without deflection or premature wear.
- Corrosion-resistant finish: 630 satin stainless (US32D) resists oxidation and surface degradation, keeping hardware performing and looking professional in high-humidity or high-traffic corridors.
Ball Bearing Performance for High-Frequency Doors
Don-Jo classifies the HWBB95045 as a high-frequency, heavy-duty ball bearing hinge designed to sustain smooth operation under constant use.
- Ball bearing pivot: Precision ball bearings reduce friction at the knuckle, extending service life on high-cycle commercial doors where standard hinges wear prematurely.
- ANSI A5111 compliance: Meeting ANSI A5111 confirms this hinge satisfies the load and dimensional requirements that architects and specifiers reference when detailing heavy door hardware schedules.
Non-Removable Pin — Standard on All HWBB Hinges
Every Don-Jo HWBB heavy-weight ball bearing hinge ships with a non-removable pin (NRP) as standard — not an upcharge.
- Factory-installed NRP: The non-removable pin prevents the hinge pin from being driven out on the exposed (exterior) side of the door, a key security requirement for out-swing commercial and institutional doors.
- Specification-ready: Because NRP is included at no additional cost, the HWBB95045 satisfies security-conscious door hardware specifications without a separate line-item adder — ideal for commercial projects with strict security schedules.
