Adams Rite B1923 Full Surface Reinforcing Pivot with 3/4" Offset for 4-1/2" Butt Hinges

Heavy-Duty Door Reinforcement Solution

The Adams Rite B1923 Reinforcing Pivot provides a cost-effective and durable solution for sagging or misaligned doors by transferring load from failed hinges to more structurally sound fastener points. Constructed from heavy-duty 3/16" cold-rolled steel with zinc-plated finish, this full-surface reinforcing pivot features a 3/4" offset specifically designed for 4-1/2" wide butt hinges. Tested for 1,500,000 cycles and supporting door weights up to 300 lbs, the B1923 extends service life of commercial door openings by shifting stress from the top hinge to screws mounted in shear.

Installation & Operation

  1. Review door condition and verify that the existing 4-1/2" butt hinges require reinforcement due to sagging or misalignment issues.
  2. Position the B1923 pivot on the door surface ensuring the 3/4" offset aligns properly with the existing hinge pivot point.
  3. Mark mounting hole locations using the symmetrical hole pattern as a template for accurate placement.
  4. Drill pilot holes and secure the reinforcing pivot using the provided mounting screws, ensuring fasteners are properly seated in shear.
  5. Test door operation to verify smooth movement and proper load transfer from the original hinge to the reinforcing pivot.
  6. Make final adjustments as needed and verify all fasteners are properly tightened. Consider tamper-proof fasteners for high-security applications.

Adams Rite B1923 US2G – Frequently Asked Questions

1) Will the Adams Rite B1923 reinforcing pivot work with my existing 4-1/2 inch butt hinges?
Yes. The B1923 is built around a 3/4 inch offset sized specifically for 4-1/2 inch wide butt hinges, so it lines up with the pivot point of a standard 4-1/2 inch commercial butt at the top of the opening. If your top hinges are a different width, the offset will not register correctly and the load transfer will not work as intended.
2) How much door weight can the B1923 reinforcing pivot carry?
Doors up to 300 lbs. The pivot is also cycle tested to 1,500,000 cycles, which is the number that matters more on a high traffic opening than the weight alone. Between the two, it covers a heavy commercial entrance that is opened constantly, which is usually where the top hinge fails in the first place.
3) My commercial door is sagging at the top hinge. Do I have to replace the door or the frame?
Not necessarily. A full surface reinforcing pivot like the B1923 is the repair for exactly that condition. It mounts on the face of the door and frame and moves the load off the failed top hinge onto fasteners set in shear at sounder points in the door and jamb. That saves pulling the door to re-core the hinge pocket, and it is why these get specified as a repair part rather than new construction hardware.
4) Is the B1923 a hinge replacement or does it work alongside the existing hinges?
It works alongside them. The B1923 is a reinforcement, not a hinge in its own right: the existing 4-1/2 inch butts stay in place and the pivot takes over the load they can no longer carry. You install it over the top hinge location, mark from its own symmetrical hole pattern, drill pilot holes, and set the supplied screws. If the hinges themselves are broken rather than loose, you are replacing hinges, not reinforcing them.
5) What is the B1923 pivot made of, and will it hold up in an exterior opening?
3/16 inch cold rolled steel with a zinc plated finish. That thickness is what lets it take the load off a failed hinge without deflecting, and the zinc plating gives it corrosion resistance for exterior and high humidity openings.
6) Will an Adams Rite reinforcing pivot fit a narrow stile aluminum storefront door?
Narrow stile aluminum doors are the primary application for Adams Rite reinforcing pivots, and hollow metal and wood door versions exist in the line as well. The B1923 itself is for flush door applications with 4-1/2 inch butt hinges. Storefront and glass front installers see top rail sag on these doors constantly, and a surface mounted pivot is the standard fix because there is no room in a narrow stile to rework the hinge prep.
7) Is this the right part for a residential interior door?
No. The B1923 is a commercial part, built for flush doors on openings that see heavy traffic, and it is sized for 4-1/2 inch butt hinges, which is a commercial hinge size rather than the 3-1/2 inch butt typical of a residential interior door. On a house door you are better served re-securing or replacing the hinge itself.
8) Do I need to buy mounting screws separately for the B1923 pivot?
Mounting screws come with it. One thing worth adding on a high security or high abuse opening: tamper proof fasteners, since a surface mounted part is reachable from the door face. Those are sourced separately.
9) What finish does the Adams Rite B1923 US2G reinforcing pivot come in?
The B1923 is offered as the US2G model, a zinc plated steel finish. Because it mounts on the face of the door and frame it will be visible, so on an opening where appearance matters, plan on it reading as plated steel rather than matching a brass or bronze hinge.
