Cal-Royal BB5200 Full Mortise Heavy Weight Four Ball Bearing Hinge, 4 1/2" x 4 1/2" - Template - Box Of 3

The Cal-Royal BB5200 is a heavy-weight commercial ball bearing hinge engineered for high-frequency commercial openings, sized 4-1/2" × 4-1/2" with template-prepared full mortise installation. Four ball bearings (two sets in the upper barrel, two sets in the lower) distribute load and wear across more contact points than standard-weight hinges, keeping the hinge smooth and squeak-free under continuous daily cycling. .180 gauge metal construction (34% thicker than standard-weight Cal-Royal BB454 hinges) provides the structural rigidity required for heavier doors, including 1-3/4" hollow metal entries, solid-core wood entrance doors, and reinforced fire-rated assemblies weighing up to 200+ lbs. Inner knuckle edges are beveled to conform precisely to the barrel shape, creating tight close-fitting joints that improve visual alignment and reduce dust and debris infiltration at the knuckle line. Five-knuckle full mortise design, eight machined screw holes (four per leaf), non-rising removable pin standard with NRP (Non-Removable Pin) variants available for security-sensitive openings. Box of 3 covers one standard commercial door (top, middle, bottom hinge positions). 

About Cal-Royal and the Heavy-Weight BB5200 Position

Cal-Royal Products is a U.S. commercial hardware manufacturer based in Los Angeles (in business since 1986), known for value-engineered architectural hardware that meets the same ANSI/BHMA grade specifications as premium-tier brands. The BB5200 is positioned at the heavy-weight tier of Cal-Royal's ball bearing hinge lineup, sitting one step above the standard-weight Cal-Royal BB454 for applications where average-frequency cycling isn't enough. Heavy-weight ball bearing hinges are specified for entrance doors, corridor doors, hospital service entrances, school main entries, retail egress doors, restaurant kitchen-to-dining service doors, and any commercial opening that sees 1,000 or more daily cycles. The BB5200 competes directly with Hager BB1191 (4-1/2" × 4-1/2"), McKinney T4A3786, Stanley FBB199, and Bommer ball-bearing heavy-weight series. For the broader Cal-Royal hinge lineup, see the Cal-Royal 5 Knuckle Ball Bearing category within Five Knuckle Ball Bearing under Commercial Hinges in Door Hinges.

When to Specify the BB5200 (and When to Step Down or Up)

The BB5200 is the right choice when three conditions align: the door is a heavy commercial door (entrance, corridor, service door, or fire-rated reinforced assembly), the opening sees high-frequency cycling (1,000+ daily uses), and the door prep is standard 4-1/2" × 4-1/2" template (the most common heavy-duty commercial door prep, larger than the 4-1/2" × 4" standard-weight prep).

If your door is lighter-weight commercial (interior office doors, retail backroom doors, classroom interiors) and sees average frequency service, step down to the Cal-Royal BB454 standard-weight 4-1/2" × 4" for substantial cost savings without compromising reliability for the application. If your application is even higher duty (high-rise main lobbies opening 5,000+ times daily, hospital surgical corridor traffic, large institutional buildings), Cal-Royal also makes specialty heavier hinges and continuous geared hinge alternatives like the Cal-Royal Continuous Geared Hinges.

For exterior outswinging doors where the hinge pin is exposed to the outside when the door is closed, specify the NRP variants (US1NRP, US26DNRP, US10BNRP, or US32DNRP). The pin cannot be removed without breaching the door first, eliminating one of the most common physical-attack vectors on outswinging exterior commercial doors. The corrosion-resistant US32DNRP is the right call for healthcare facility exterior doors, food service kitchen exteriors, marine/coastal applications, and any environment where stainless construction extends service life.

Comparable Alternatives in the Catalog

For direct comparison shopping across major brand alternatives in similar size and weight, the Hager BB1191 4-1/2" × 4-1/2" is the closest premium-tier equivalent, with its NRP variant the Hager BB1191-NRP 4-1/2" for security-enhanced specs. For lighter-weight Hager alternatives in different sizes, see Hager BB1191 4" × 4" and Hager BB1191 3-1/2" × 3-1/2". For specialty heavy-duty applications, the Hager HTBB1279 with Hospital Tip eliminates pin-end exposure that catches IV poles or wheelchair handles in healthcare corridors, and the Hager RCBB1279 Round Corner handles round-corner door preparation common in older institutional construction.
