ABH A110 WT HD C 079 – Frequently Asked Questions

1) What does wide throw mean on a continuous geared hinge, and when do I need one?
Wide throw pushes the door further away from the frame when it swings open, giving extra clearance where a standard throw hinge would let the door bind on the frame, trim, or a deep reveal. On lead-lined openings the door is thicker than usual, so the extra throw is often what makes the door clear the jamb at all. If your opening has no obstruction and the door swings free on a standard hinge, you don't need the wide throw version.
2) Is the ABH A110WTHD approved for a fire rated door?
Approved for metal swinging fire doors up to 90 minutes and wood swinging fire doors up to 60 minutes. So a 90 minute hollow metal opening is covered, but a 90 minute wood door is not, that stops at 60. Check the label on your door leaf against those two numbers before you specify.
3) Does the ABH A110WTHD meet BHMA Grade 1 for a hospital or government spec?
It is certified to BHMA 156.25 Grade 1, which is the continuous hinge standard and the top grade in it. It's also BAA qualified, which matters on federally funded work where Buy American Act sourcing is a condition of the contract. Between the Grade 1 certification and the BAA qualification it clears the two boxes most institutional specs put on a continuous hinge.
4) Full mortise or full surface continuous hinge, which one do I need?
Full mortise, like the A110WTHD, sets into the door edge and the frame rabbet and gives a flush look, which is what most new lead-lined and hollow metal openings are prepped for. Full surface mounts on the face of the door and frame instead and is the retrofit answer when the existing door or frame is chewed up from old butt hinges or you can't machine the edge. ZenSupply carries the full surface equivalents, including the Design Hardware Full Surface Heavy Duty geared hinge and the BEST 664HD full surface. There's also a full surface offset version from Design Hardware for openings where the door has to clear an obstruction on the pull side.
5) What else could I use instead of the ABH A110WTHD if I don't need the lead lining?
If the opening isn't an X-ray or imaging room, the lead lining is cost you don't need. The Design Hardware Full Mortise Heavy Duty continuous geared hinge is the same mounting type at heavy duty. Pemko's FM-RG Series is a Grade 1 aluminum full mortise raised geared hinge, and Pemko also does a short leaf flush full mortise in Grade 1. All of those are full mortise, so they drop into the same prep. What none of them replace is the lead lining, so keep the A110WTHD on any door with lead in the core.
6) What is the closest full mortise geared continuous hinge to the ABH A110WTHD if the door is not lead lined?
The ABH A110WTHD is a heavy duty full mortise aluminum continuous gear hinge built with lead lining and a wide throw leaf for openings needing extra clearance. On a standard hollow metal or wood door with no radiation shielding, the Design Hardware FMHD full mortise heavy duty continuous geared hinge covers the same mounting condition at the same duty level, and the Pemko FM-RG Series Grade 1 aluminum full mortise raised geared continuous hinge is another full mortise aluminum option carrying Grade 1 construction with a 180 degree swing. Both mortise into the door and frame edge the same way, so the frame prep logic does not change - what you give up is the lead lining and the wide throw offset.
7) The frame will not take a mortised hinge leaf - what continuous hinge should I use instead of the ABH A110WTHD?
The A110WTHD is a full mortise hinge, so both leaves seat into prepped door and frame edges. Where the existing frame cannot be prepped, a surface mounted continuous geared hinge applies to the face instead: the Design Hardware FSHD full surface heavy duty continuous geared hinge, the Design Hardware FSOHD full surface offset heavy duty continuous geared hinge for openings where the door must clear a wall or trim condition, and the BEST 664HD heavy duty full surface continuous geared hinge, which carries a 90 minute UL fire rating. NGP also lists the HD5700 full surface geared hinge built with a 1/16 inch door inset for 1-3/4 inch to 2-1/4 inch doors.
8) Is a BEST 641 continuous hinge an acceptable substitute for the ABH A110WTHD?
They are not the same class of hinge. The BEST 641 is a steel full mortise standard duty continuous hinge with hospital tips, listed at medium duty, and the BEST 651 stainless steel full mortise hinge with hospital tips is also medium duty. The ABH A110WTHD is a heavy duty aluminum geared hinge rated for doors up to 450 lbs and 48 inch width, with lead lining. The 641 and 651 match the full mortise mounting, so they suit a lighter interior opening or one where hospital tips are specified, but they are not a like-for-like swap on a heavy leaf or on a lead lined door.
9) I need a BHMA Grade 1 continuous hinge for a facility standard - which options besides the ABH A110WTHD carry Grade 1?
The ABH A110WTHD is BHMA 156.25 Grade 1 certified. Among other continuous geared hinges, the Pemko CFM84SLF-HD1 84 inch full mortise short leaf flush heavy duty hinge is Grade 1, the Pemko FM-RG Series aluminum full mortise raised geared hinge is Grade 1, the Pemko FM-SLF short leaf flush geared hinge for 1-3/8 inch doors is Grade 1, and the Pemko DSH1000 anti-barricade hinge with 100 degree bidirectional operation is Grade 1. The NGP HD1100A concealed continuous geared hinge is listed at Grade 3, so it does not meet a Grade 1 facility standard.
10) Which continuous hinge do I use for a 90 minute fire door if the ABH A110WTHD does not fit the opening?
The ABH A110WTHD is approved for metal swinging fire doors up to 90 minutes and wood swinging fire doors up to 60 minutes. If the mounting condition rules it out, the BEST 663HD heavy duty continuous hinge is 90 minute UL fire rated and built for 3/32 inch inset doors, and the BEST 664HD heavy duty full surface geared hinge also carries a 90 minute UL fire rating. On the NGP side, the HD1100A concealed hinge, the HD5400A half surface hinge, and the HD5700 full surface hinge are each listed 10C fire rated 90 minute on hollow metal. Confirm the fire rating applies to your door substrate before you order.
11) Can I put the ABH A110WTHD on a 1-3/8 inch door?
The A110WTHD is a heavy duty full mortise hinge intended for commercial doors and is rated for leaves up to 450 lbs and 48 inch width, which is a heavier and thicker door than a 1-3/8 inch leaf. For a 1-3/8 inch door, the Pemko FM-SLF short leaf flush continuous geared hinge is built specifically for that thickness and carries Grade 1 construction. The NGP HD5700 is built for 1-3/4 inch to 2-1/4 inch doors, so it is the wrong direction for a thin leaf.
12) Will a continuous geared hinge stop my heavy door from sagging?
That's the main reason to use one. A continuous hinge like the A110WTHD carries the load along the entire height of the door instead of concentrating it on three or four butt hinge points, so the door doesn't drop, drag on the threshold, or throw the top corner out of the frame. On a 450 lb lead-lined leaf that's not a refinement, it's the difference between a door that stays in alignment and a service call every few months.
13) I'm replacing butt hinges on an existing door. Will the A110WTHD cover the old cut-outs?
Yes. Running the full height of the door, it covers the old butt hinge mortises rather than leaving you to fill and refinish them. Do confirm the door edge and frame rabbet will take a full mortise leaf. Where the existing edge is too damaged to machine cleanly, a full surface hinge such as the Design Hardware Full Surface Heavy Duty is the better retrofit because it mounts on the face instead.
14) How do I know the ABH A110WTHD will replace the geared hinge already on the door?
ABH publishes a cross reference chart for its aluminum continuous geared hinges, which maps competitor models to the ABH equivalent, and a door clearance chart that tells you the clearance the hinge needs against your door edge and frame condition. Between the two you can confirm the swap before you order rather than after the door is off its hinges. Both are attached to the A110WTHD along with the A110WT wide throw full mortise cut sheet.
15) Do I have to specify a door inset when ordering the ABH A110WTHD?
No inset to select. Every A110WTHD is built with no door inset, so you order by length and finish only. That's a difference worth catching if you're cross shopping, some geared hinges are inset specific, for instance the NGP HD5700 is built for a 1/16 inch door inset and the BEST 663HD for 3/32 inch inset doors. Order one of those against the wrong inset and it won't sit right on the opening.
16) Is a standard duty continuous hinge enough, or do I need heavy duty?
Duty level follows door weight and traffic. The A110WTHD is heavy duty, rated to 450 lbs, which is where you want to be on a lead-lined leaf or a high cycle entrance. For lighter interior doors on ordinary traffic, ZenSupply carries medium duty options such as the BEST 641 steel full mortise and the BEST 651 stainless steel, both with hospital tips, which is the sloped tip that keeps linens and gurney cords from catching in a healthcare corridor. Going too light on a heavy door is how you end up back on site.
17) What is the difference between the ABH A110WTHD wide throw hinge and an offset or half surface continuous hinge?
The A110WTHD uses a wide throw design to give extra clearance for door and frame applications that need additional space, while still mounting as a full mortise hinge into prepped edges. The Design Hardware FSOHD full surface offset heavy duty geared hinge achieves clearance through an offset geometry mounted to the door and frame faces rather than into them, and the NGP HD5400A is a half surface aluminum alloy geared hinge, meaning one leaf mounts to a face and the other into a prepped edge. All three are ways of buying clearance or working around frame prep, but they are three different preps - pick from what the existing opening will actually accept.
18) Does the ABH A110WTHD do anything for behavioral health or anti-ligature openings?
No. The A110WTHD is a lead lined heavy duty geared hinge whose added function is radiation shielding continuity and security at the hinge edge, eliminating the door-to-frame gap that invites prying. An anti-barricade opening is a different requirement, and the Pemko DSH1000 anti-barricade continuous hinge with 100 degree bidirectional operation is the hinge built for it, in Grade 1 construction. If the specification calls for a door that can swing both directions to defeat a barricade, the lead lined hinge does not answer it.
19) I need the hinge hidden when the door is closed - is the ABH A110WTHD concealed?
The A110WTHD is a full mortise geared hinge, so the gear edge reads along the hinge side of the opening. Where the specification calls for the hinge to be concealed, the NGP HD1100A is a concealed continuous geared hinge in an 83 inch length, listed 10C fire rated 90 minute on hollow metal at Grade 3. Note the grade difference before substituting into a Grade 1 spec.
20) Which full mortise continuous hinge should I standardize on across a building if some doors are 84 inches?
The ABH A110WTHD is offered in 79 inch, 83 inch, 85 inch, 95 inch and 120 inch lengths in Black, Clear Anodized Aluminum and Dark Bronze, all built for lead lined doors. Where the shielded openings are the exception and the rest of the building is standard commercial, the Pemko CFM84SLF-HD1 is an 84 inch full mortise short leaf flush heavy duty Grade 1 hinge, and the Design Hardware FMHD full mortise heavy duty geared hinge is another full mortise heavy duty option. Keeping the mounting type constant across the building keeps the frame prep and the hanging procedure the same even where the model changes.
21) Does a continuous hinge improve security on an exterior or secure room door?
It removes the gap between the door and the frame along the full hinge edge, so there's nowhere to get a pry bar in and no exposed hinge pins to pull. On a lead-lined imaging or records room that's a real benefit, you're already controlling access and the hinge edge is usually the soft spot left on those openings.
