ABH A953 R US32D – Frequently Asked Questions

1) What does a cam lift hinge like the ABH A953 actually do, and when do I need one instead of a standard butt hinge?
A cam lift hinge raises the door as it swings open. The A953 gives 1/4 inch of lift, which carries the bottom of the door up over a threshold, a raised saddle, carpet, or an uneven floor that a standard butt hinge would drag on. If the floor under the swing is flat and the undercut is already adequate, you don't need lift and a conventional full mortise butt hinge is the simpler buy. Use the cam lift where the door has to clear something on the way open and you don't want to undercut the leaf.
2) How much clearance do I need at the head of the frame to install an ABH A953 cam lift hinge?
Minimum 3/16 inch at the head of the frame for doors up to 1-3/4 inches thick, and 1/4 inch for doors thicker than 1-3/4 inches. The door rises as it opens, so if that gap isn't there the top rail binds on the frame head. Check the existing gap before you order, because a tight-fitted door in a snug frame may need the top edge dressed down first.
3) Will an ABH A953 drop into my existing 4-1/2 x 4-1/2 hinge mortise?
No, not without cutting. The A953 leaf is 5 x 4.5 inches, so it is taller than a standard 4-1/2 by 4-1/2 prep and the mortise has to be lengthened. Corners are 1/4 inch radius, which matches a routed radius-corner prep rather than a square-corner one. On a hollow metal frame with existing 4-1/2 square prep, plan on frame work or specify a different size.
4) Is the ABH A953 hinge stainless steel all the way through, including the pin?
Body is US304 stainless steel and the pin is 420 J2 stainless. That combination is what you want on exterior openings, pool and locker rooms, kitchens, and coastal buildings where a plated steel hinge pin rusts and seizes. Painted and plated finishes are applied over that stainless body, so the corrosion resistance is in the base metal, not the coating.
5) Can I use a cam lift hinge to make a door self-closing?
Partly, and it should not be your closer. Because the A953 lifts the door 1/4 inch on opening, the leaf's own weight tends to bring it back toward closed once released. That is a byproduct of the lift geometry, not a controlled closing device, and it does not give you latching force, backcheck, or closing speed control. On a fire or life-safety opening, or anywhere a door has to positively latch, hang a proper door closer and treat the lift as clearance only.
6) Is the ABH A953 a continuous geared hinge or an individual hinge?
It is an individual full mortise hinge, 5 x 4.5 inches, mortised into the door edge and frame rabbet the way a butt hinge is. It is not a full-length geared continuous hinge running the height of the door. If your opening is high-traffic enough that you were looking at a continuous hinge to spread the load, the A953 is a different solution: it solves floor clearance, not hinge-point wear along the edge.
7) How many cam lift hinges do I need per door, and can I mix them with regular hinges?
Don't mix. Every hinge on the leaf has to lift together or the door binds and racks, so all hinges on a cam lift opening are cam lift hinges of the same handing and lift, in this case 1/4 inch. Order a matched set for the opening. The 300 lb rating is what you check the leaf weight against when deciding how many points the door needs.
8) Will a 1/4 inch lift hinge clear the carpet and threshold in a healthcare or office corridor retrofit?
1/4 inch of rise at the bottom of the leaf is what the A953 delivers, which clears typical commercial carpet, a transition strip, or a low saddle. Measure the actual obstruction height at the widest point of the swing arc before committing, because a tall thermal threshold or a thick pad-and-carpet build can exceed that. It is a commercial-rated hinge and it is used in office, education, healthcare, retail, industrial, multi-tenant residential, and municipal buildings.
9) What finishes does the ABH A953 cam lift hinge come in?
Thirteen finishes, in both handings: painted aluminum, painted brass, painted bronze, painted black, painted dark bronze, painted white, satin bronze, oil rubbed bronze, bright brass, bright bronze, bright stainless steel, satin stainless steel, and satin brass. If you are matching an existing fleet of openings, the painted whites and aluminums are the ones that blend into a painted hollow metal frame, and the satin stainless matches most commercial lever and closer hardware.
