ABH A950 R US32D – Frequently Asked Questions

1) Will the ABH A950 cam lift hinge clear a thick carpet or a raised threshold when the door swings?
The A950 raises the door 5/16 inch as it opens, which is what lets a door pass over carpet, a mat, or a raised threshold instead of dragging on it. Two clearance conditions have to be met at the frame for that lift to work: a minimum of 3/16 inch at the head of the frame, and 1/4 inch if the door is thicker than 1-3/4 inches. If your head clearance is tighter than that, the door will bind at the top as it rises.
2) Do I have to specify handing when ordering an ABH A950 cam lift hinge?
Yes, and getting it wrong means the hinge won't work. The A950 is a handed mortise hinge, ordered left hand or right hand. A cam lift hinge only lifts in one direction of swing, so a left hand hinge will not function on a right hand door. Determine the door's hand before you order, and order every hinge on that leaf to match.
3) What door and frame prep does the ABH A950 need, and does the frame have to be reinforced?
It's a full mortise hinge, so both the door edge and the frame rabbet get mortised for a 4.5 x 5 inch leaf, same as a standard butt hinge prep. The mounting requirement is the part people miss: screws must engage no less than .350 inch into ASTM A-36 steel reinforcement. On a hollow metal frame with proper hinge reinforcement that's a non-issue. On a frame or door without that reinforcement, add it before hanging a 500 lb leaf on this hinge.
4) Can the ABH A950 replace a standard 4-1/2 x 4-1/2 butt hinge on an existing door?
Not as a straight drop-in. The A950 leaf measures 4.5 x 5 inches, so the mortise is a different size than a 4-1/2 x 4-1/2 butt prep and needs to be cut to suit. You also need to confirm 3/16 inch clearance at the head of the frame (1/4 inch if the door is over 1-3/4 inches thick), because the door is going to climb 5/16 inch that it wasn't climbing before. On new openings that's designed in; on a retrofit it's the thing to check first.
5) Should I use a cam lift hinge or just a rising butt hinge to get a door over carpet?
A cam lift hinge like the A950 is the heavier-duty answer. It lifts the leaf a fixed 5/16 inch on a cam as the door opens and is rated to 500 lbs, so it suits commercial openings with heavy doors and constant use. If the goal is only to clear a low pile of carpet on a light interior door, a lighter rising hinge does that job with less door and frame prep. Once the door is heavy, or the opening is a school, hospital, or warehouse, the cam lift is what holds up.
6) Will the ABH A950 hinge rust in a kitchen, pool area, or exterior opening?
The hinge body is US304 stainless and the pin is 420 J2 stainless, which is the corrosion-resistant combination you want in wet, humid, or washdown environments. Note that most of the finish choices are painted or plated over that body; if corrosion resistance is the whole point, the bright or satin stainless steel finishes leave the stainless exposed rather than coated.
7) How many ABH A950 cam lift hinges do I need per door?
The A950 is sold as a single hinge, so order the quantity your leaf calls for and make sure every one is the same hand and finish. Standard commercial practice is three hinges on a door up to 7 feet 6 inches and a fourth above that. On a lift application all hinges on the leaf must be cam lift hinges of the same 5/16 inch lift, or the door will bind instead of rising evenly.
8) What finishes does the ABH A950 cam lift hinge come in, and can I match the other hardware in the building?
Thirteen finishes, each available in both hands: Painted Aluminum, Painted Brass, Painted Bronze, Painted Black, Painted Dark Bronze, Painted White, Oil Rubbed Bronze, Bright Stainless Steel, Bright Brass, Satin Brass, Satin Stainless Steel, Satin Bronze, and Bright Bronze. That spread covers the usual commercial specs, so a property manager standardizing across a floor can match the A950 to existing lever and closer finishes rather than having one odd door.
