HAGER COMMERCIAL HINGES

Today, the Hager name is synonymous with architectural hinges. In fact, they are the industry’s premiere designer and manufacturer of architectural hinges, with a product line that offers one of the widest varieties of sizes, shapes, and finishes--all of which meet or exceed ANSI standards.
  • Hinges are manufactured in accordance with ANSI/BHMA A156.1. Self-closing hinges and pivots are in accordance with ANSI/BHMA A156.17 using three hinges per opening on a 3’0” x 7’0” x 1-3/4” (914 mm x 2134 mm x 44 mm) door. 
  • Round corners are available in 1/4” (6 mm) (standard) or 5/8” (16 mm) radius.
  • Full Mortise Both leaves are mortised, one leaf in the door and one leaf in the frame (wood door or hollow metal door with wood frame or hollow metal frame). Example: BB1279, 4-1/2” x 4-1/2” (114 mm x 114 mm), US26D.
  • Half Mortise One leaf is mortised in the door and the other is surface applied to the frame (hollow metal door with channel iron frame). Example: BB1109, 4-1/2” (114 mm), US26D.
  • Full Surface Both leaves are applied to the surface, one to the door and the other to the frame (metal core door or hollow metal door with channel iron frame). Example: BB2171, 5” (127 mm), USP.
  • Half Surface One leaf is mortised in the frame and the other is surface applied to the face of the door (wood door with wood frame or metal core door with hollow metal frame) Example: BB1163, 5” (152 mm), US26D.

Hager BB1191-4.5x4.5-32D – Frequently Asked Questions

1) What doors is the Hager BB1191 hinge designed for?
This standard weight hinge works on interior and exterior doors up to 200 pounds. Best for residential and light commercial applications. Verify door weight before installation.
2) Is this hinge reversible for left or right hand doors?
Yes, full mortise hinges are reversible. Same hinge works for left hand or right hand door swing. No separate models needed.
3) What is the brass finish on this hinge?
This features a natural brass finish that will develop patina over time. For specific finish codes or protective coatings, check with manufacturer specifications.
4) How many ball bearings does this hinge have?
Ball bearing hinges typically have bearings in each knuckle joint. The BB1191 has 5 knuckles providing smooth operation and reduced wear over time.
5) What grade rating does this hinge meet?
Check manufacturer specifications for ANSI grade rating. Standard weight hinges typically meet residential requirements. Verify grade requirements for your specific application.
6) Does this work with fire rated door assemblies?
Fire rated doors require listed hinges. Verify this model appears on fire door manufacturer's approved hardware list before use in fire assemblies.
7) Are screws included with this hinge?
Most Hager hinges include machine screws. Use screws provided or equivalent length and thread pitch. Wood screws may be needed for wood door frames.
8) How do I mortise this hinge into the door?
Use manufacturer template for exact mortise dimensions. Route both door edge and frame to hinge leaf thickness. Test fit before final installation. Ensure pin removal side faces correct direction.
9) How often do ball bearing hinges need maintenance?
Ball bearing hinges are low maintenance. Check screws annually for tightness. Clean with mild detergent. Avoid over-lubrication as bearings are factory sealed.
10) What other Hager hinge models are similar?
Browse our hinges section for other Hager models. Consider heavy weight versions for doors over 200 pounds or high frequency applications.
11) Can this hinge handle high humidity conditions?
Brass naturally resists corrosion better than steel. Suitable for most interior applications. For extreme moisture conditions, consider stainless steel alternatives.
12) What are the standard dimensions for this hinge size?
Check manufacturer specifications for exact dimensions. Standard residential hinges are typically 4 inches in height. Verify measurements match your door preparation before ordering.
