ABH ABH-A111WT-CL-79 – Frequently Asked Questions

1) What is a wide throw continuous hinge for, and do I need one instead of a standard continuous hinge?
Wide throw is about clearance. The ABH A111WT is a full mortise aluminum continuous geared hinge built with extra throw so the door swings clear of deep trim, thick frames, brick mould, or a wall return that a standard-throw hinge would bind against. If your opening is a plain hollow metal frame with nothing projecting past the face, you do not need the extra throw and a standard full mortise geared hinge like the Design Hardware FMHD or the Pemko FM-RG Series covers it. Reach for the A111WT when something on the jamb side is in the door's path at the open position.
2) How heavy a door will the ABH A111WT continuous hinge carry?
450 lbs, on doors up to 48 inches wide. That covers most commercial hollow metal and solid core wood leaves, including wide entry leaves and heavy lead lined or acoustic doors within that width. Past 48 inches wide the door is outside what the A111WT is rated for, no matter what it weighs.
3) Can I use the A111WT on a fire rated door?
Yes, within limits that depend on the door material. The A111WT is approved for metal swinging fire doors rated up to and including 90 minutes, and wood swinging fire doors up to and including 60 minutes. So a 90 minute hollow metal stair door is fine; a 90 minute wood door is not, and you would need a hinge carrying a 90 minute wood approval instead.
4) Do I have to mortise the door and frame to install the ABH A111WT?
No. It goes on surface applied, with no mortising of the door or the frame, and the leaf covers over old butt hinge cut outs, which is what makes it a practical retrofit on a beat up opening. No door or frame reinforcement is required for standard applications, and the hole pattern is templated.
5) Will a continuous geared hinge stop my door from sagging and dragging on the threshold?
That is the main reason to swap to one. A butt hinge carries the whole leaf on three or four points, and those points work loose or elongate until the door drops. The A111WT runs the full height of the leaf and distributes the weight across the entire door and frame, which is what eliminates the binding and sagging. On an opening you have already reshimmed twice, the continuous hinge is the fix rather than another set of heavier butts.
6) What is the difference between a full mortise and a full surface continuous hinge, and which one do I need?
Full mortise, which is what the A111WT is, sits between the door edge and the frame rabbet, so the hinge is hidden when the door is closed and you need the door to be removable from the frame to install it. Full surface mounts on the face of the door and the face of the frame, so it is the one to use when the frame has no usable rabbet, the door is warped, or you cannot pull the leaf. If your opening calls for full surface instead, the Design Hardware FSHD and the BEST 664HD are full surface geared hinges, and the Design Hardware FSOHD is the full surface offset version.
7) What is the closest equivalent to the ABH A111WT if I need a Grade 1 aluminum full mortise geared continuous hinge?
The Pemko FM-RG Series is the nearest peer: a Grade 1 aluminum full mortise raised geared continuous hinge with 180-degree swing. Both are full mortise geared hinges that mount into the door and frame edge rather than on the face. The A111WT differs in intent - it is the wide throw version, engineered to give extra clearance between door and frame, and it is BHMA Grade 1 certified for doors up to 450 lbs. Specify the FM-RG where a standard throw is acceptable and the A111WT where trim, a deep frame, or a wall return means the door needs to swing clear of an obstruction.
8) The door edge is already mortised for butt hinges and I cannot mortise the frame - what do I use instead of a wide throw full mortise geared hinge?
Go to a full surface hinge. The Design Hardware FSHD is a heavy duty full surface continuous geared hinge, and the NGP HD5700 is a full surface continuous geared hinge with 1/16 inch door inset sized for 1-3/4 inch to 2-1/4 inch doors. Full surface leaves apply to the face of the door and the face of the frame, so no edge prep is required on either. The ABH A111WT is a full mortise hinge, which takes the leaf into the door edge and frame rebate. If the frame is the only thing you cannot touch, the NGP HD5400A is a half surface geared hinge - one leaf on the door face, one into the frame.
9) Is a BEST 641 or 651 continuous hinge a drop-in substitute for an ABH A111WT?
They are not equivalents. The BEST 641 is a steel full mortise standard duty continuous hinge with hospital tips and the BEST 651 is a stainless steel full mortise continuous hinge with hospital tips, both rated medium duty. The ABH A111WT is an aluminum geared hinge carrying BHMA Grade 1 certification for doors up to 450 lbs and up to 48 inches wide. The 641 and 651 are also hospital tip pin-and-barrel style hinges rather than geared, so the leaf profile and the hole pattern are different. Where the opening is a lighter interior door and the specification calls for hospital tips - psychiatric, detention, and some healthcare work - the BEST 641 or 651 is the correct part; where the spec calls for a Grade 1 geared hinge, it is not.
10) For a 90 minute fire rated hollow metal opening, what geared continuous hinges qualify besides the ABH A111WT?
The ABH A111WT is approved for metal swinging fire doors rated up to and including 90 minutes and wood swinging fire doors up to and including 60 minutes. Among geared peers, the NGP HD1100A, NGP HD5400A, and NGP HD5700 all carry a 10C fire rating of 90 minutes on hollow metal, and the BEST 663HD and BEST 664HD are heavy duty continuous hinges with a 90-minute UL fire rating - the 663HD for 3/32 inch inset doors and the 664HD in a full surface configuration. All handle the 90 minute hollow metal opening; the choice comes down to mortise versus surface mounting and, for the A111WT, whether the opening also needs wide throw clearance.
11) What finishes is the ABH A111WT wide throw hinge available in?
Three: clear anodized aluminum, dark bronze, and black. All three are offered in every stock length, so a dark bronze storefront run and a clear anodized back of house run can use the same hinge in the length each opening needs. Clear anodized is the usual match to aluminum storefront and mill finish frames; dark bronze pairs with bronze anodized entrances.
12) Do screws come with the ABH A111WT continuous hinge, and what size are they?
Fasteners are 12-24 x 3/4 inch undercut self drilling, thread forming tek machine screws. They form their own threads in hollow metal, so you are not tapping the frame or the door edge on site. Note the 3/4 inch length if you are going into anything other than standard sheet metal, and plan wood door attachment accordingly.
13) Is the ABH A111WT Grade 1, and what does that actually mean for a high traffic door?
It is certified to BHMA 156.25 Grade 1, the top tier in that standard for continuous hinges. In practice that means it is tested for the cycle counts and load a heavy use opening sees, which is the reason it goes on lobby entries, classroom corridors and hospital doors rather than a closet. Among comparable continuous hinges we carry, the Pemko FM-RG Series and the Pemko 84 inch full mortise short leaf flush hinge are also Grade 1.
14) Does a continuous hinge improve security on an out-swinging door?
It closes the gap. The A111WT eliminates the gap between door and frame along the full height of the leaf, so there is no purchase point for a pry bar at the hinge edge, and no exposed hinge pins to pull. On an out-swinging exterior door where butt hinges leave the knuckle on the outside, that is a real difference. It does not replace the lock or a security astragal on a pair.
15) Is the ABH A111WT Buy American compliant for a federal or public job?
It is BAA qualified, so it can go on a Buy American Act project. That plus BHMA Grade 1 certification is usually what a government, school district or GSA spec is asking for on a continuous hinge line item.
16) Which continuous hinge should I standardize on across a facility if some openings need wide throw and others do not?
Keep the ABH A111WT for the openings that need clearance - it is the wide throw full mortise geared hinge, BHMA Grade 1 certified, rated for doors up to 450 lbs and 48 inches wide, in lengths from 79 inches to 120 inches and in clear anodized aluminum, dark bronze, and black. For standard throw full mortise openings in the same building, the Pemko CFM84SLF-HD1 is an 84 inch full mortise short leaf flush heavy duty Grade 1 hinge and the Pemko FM-RG Series is a Grade 1 aluminum full mortise raised geared hinge. All three hold a Grade 1 line, so a facility standard written to Grade 1 full mortise continuous hinges is satisfied by the whole group, and the throw and leaf style are chosen opening by opening.
17) Is the Pemko DSH1000 anti-barricade hinge an alternative to the ABH A111WT?
It solves a different problem. The Pemko DSH1000 is a Grade 1 anti-barricade continuous hinge with 100-degree bidirectional operation, meaning the door can be swung either direction so an occupant cannot block the opening from inside - behavioral health rooms, patient toilets, dormitory and school restrooms. The ABH A111WT is a single-direction wide throw full mortise geared hinge, BHMA Grade 1, for doors up to 450 lbs. Both carry Grade 1, but only the DSH1000 provides bidirectional swing; specify it when the room needs anti-barricade egress and the A111WT when the requirement is clearance and load on a conventional swing.
18) The door has to clear a projecting wall return - what continuous hinge options give offset swing?
Two directions. The ABH A111WT is the wide throw full mortise geared hinge, engineered to add clearance between door and frame while keeping the leaf inside the mortise, and it is BHMA Grade 1 for doors up to 450 lbs and 48 inches wide. The Design Hardware FSOHD is a full surface offset heavy duty continuous geared hinge, which takes the pivot point outboard on the face of the door and frame. The A111WT keeps the mortised appearance and needs edge prep; the FSOHD surface applies and produces a larger offset. Measure the obstruction against the throw needed before choosing between them.
19) What is the difference between the Design Hardware FMHD and the ABH A111WT for a heavy commercial opening?
Both are full mortise heavy duty continuous geared hinges. The Design Hardware FMHD is listed at heavy duty. The ABH A111WT is BHMA Grade 1 certified to BHMA 156.25, rated for doors up to 450 lbs and 48 inches maximum width, and ships with 12-24 x 3/4 inch undercut self drilling thread forming tek machine screws. The A111WT is specifically the wide throw variant, adding clearance between door and frame; the FMHD is a standard full mortise geared hinge. On a heavy interior or entrance door with no clearance obstruction, either configuration is a full mortise geared solution - the wide throw is what you are paying for on the A111WT.
20) Which continuous hinge do I use when the door is 3/32 inch inset and I cannot use a wide throw hinge?
The BEST 663HD is the part for that condition - a heavy duty continuous hinge, 90 minute UL fire rated, built specifically for 3/32 inch inset doors. Inset dimension has to match the hinge geometry or the door will not close square against the stop. The ABH A111WT is a wide throw full mortise geared hinge whose leaf geometry is set for extra door-to-frame clearance rather than a specified inset. Confirm the inset at the opening before ordering either.
21) For a federally funded project requiring domestic hardware, how does the ABH A111WT compare to other heavy duty continuous geared hinges?
The ABH A111WT is BAA qualified and BHMA Grade 1 certified, rated for commercial use on doors up to 450 lbs, and available in 79, 83, 85, 95, and 120 inch lengths. Among heavy duty geared peers, the Design Hardware FMHD is full mortise heavy duty, the FSHD is full surface heavy duty, and the FSOHD is full surface offset heavy duty. If the submittal carries a domestic sourcing line, the A111WT holds that line as well as the Grade 1 line, and the mounting style is then chosen from what the door and frame will accept.
22) How many bearings are in an 83 inch ABH continuous hinge?
The 83 inch A111WT carries 32 bearings at 3 inch spacing on center. That spacing is what keeps the pivot load spread evenly down the leaf instead of concentrating it, and it is why the door keeps swinging smoothly on a high cycle opening rather than getting stiff at one point in the arc.
23) Will an aluminum geared hinge hold up in an industrial or warehouse door opening?
Anodized aluminum construction at Grade 1 with a 450 lb capacity is what ABH builds the A111WT for, and industrial and warehouse doors are among its stated applications along with high traffic commercial entrances, healthcare and schools. The aluminum body is not a downgrade from steel here; the geared full length design is carrying the load in shear along the whole leaf rather than at three knuckles. It is a commercial rated product, not a residential one.
