BB5200 4-1/2 x 4-1/2-Inch Heavy-Weight Full-Mortise Hinge

Our BB5200 hinge combines a 4-1/2 x 4-1/2-inch size, .180-inch leaf thickness, and four ball bearings in a heavy-weight, full-mortise design. It is an option for appropriately specified heavy doors or high-frequency openings when the door, frame, reinforcement, and hardware schedule support this hinge configuration.

BB5200 Specifications

  • Mounting: Full mortise, with one leaf recessed into the door and the other into the frame.
  • Size: 4-1/2 x 4-1/2 inches.
  • Thickness: .180 inch.
  • Weight class: Heavy weight.
  • Bearing arrangement: Four ball bearings.
  • Construction: Five-knuckle, template-type hinge.
  • Order unit: Priced and sold individually as each; the catalog inner-box quantity is three hinges. Do not assume one each is a three-hinge set.

Current Finish Choices

Select the actual offered finish: US26D Satin Chrome, US32D Satin Stainless Steel, US10A, US10B Antique Bronze Oiled, US26 Bright Chrome, US3 Bright Brass, or USP Primed Gray. Confirm the specified base material and environmental suitability rather than assuming a decorative finish name identifies every component's construction.

Practical Uses

  • Specified heavy-door hardware: Provides a heavy-weight four-bearing configuration for compatible commercial openings.
  • Higher-frequency door schedules: Consider BB5200 where the project calls for heavy-weight ball-bearing hinges rather than standard-weight or plain-bearing hardware.
  • Replacement projects: Match existing hinge dimensions, leaf thickness, screw pattern, and reinforcement before selecting the replacement.

Everyday example: A facilities technician replacing worn hinges on a busy corridor door checks the door weight, closer forces, hinge count, and existing mortises. They compare the BB5200 template with the door and frame preparation, select the specified finish, and test the complete swing and latch alignment after installation. A new hinge is not used to conceal damaged reinforcement or an out-of-square frame.

Installation and Preparation

  • Review the complete opening: Confirm door size, weight, use frequency, closer forces, and required hinge quantity and spacing.
  • Match the mortises: Check leaf size and .180-inch thickness against the existing recesses. Equal height and width do not make standard- and heavy-weight leaves interchangeable.
  • Use the exact template: Verify screw positions, clearances, and door/frame preparation before drilling or machining.
  • Verify fastening: The BB5200 template references #12-24 x 1/2-inch machine screws and #12 x 1-1/4-inch wood screws. Use the actual supplied hardware and approved substrate preparation.
  • Align the hinges: Seat the leaves correctly and keep hinge axes aligned without forcing the door into position.
  • Test before service: Check swing, door gaps, closer operation, latch engagement, and secure fastening.

Material, Pin Security and Rated-Opening Checks

Our architectural hinge family includes steel, stainless-steel, and separately specified brass constructions. Choose the actual material for the opening and exposure. Plating or an added protective finish does not make a steel hinge rustproof.

NRP means non-removable pin. This ordering feature uses a retaining provision to prevent pin removal with the door closed. Verify it where required, particularly when the pin is exposed on an outswing opening; do not assume an unmarked BB5200 selection includes NRP. Special tips, pins, or other factory options must be separately specified.

Our commercial catalog identifies UL-listed steel and stainless-steel BB5200 hinges for swinging fire-door applications, with a 3-hour reference. Confirm the exact listed hardware, fasteners, preparation, and approved door-and-frame assembly. Do not transfer that reference to brass construction or treat the hinge alone as proof of a complete opening's rating.

Problems It Helps Address

  • The specification calls for heavy-weight bearing hardware: Identifies the four-bearing, .180-inch BB5200 construction.
  • A replacement must match deeper hinge preparation: Distinguishes heavy-weight leaf thickness from standard-weight hardware.
  • A coordinated finish is needed: Offers the listed finishes while keeping material selection separate.
  • Operation has become inconsistent: A correctly selected replacement can help restore hinge movement when the door, frame, and mounting points are sound.

Care

Periodically inspect fastening, alignment, bearing movement, finish condition, and door clearances. Correct loose reinforcement, sagging, or binding rather than forcing operation. Follow the supplied maintenance guidance and use cleaning methods appropriate to the selected finish.
