ABH A170 HD C 079 – Frequently Asked Questions

1) Will the ABH A170 continuous gear hinge carry a heavy 4-foot-wide commercial door?
The A170HD full mortise geared hinge is rated for a 450 lb door leaf up to 48 inches wide. If the door is lead lined and runs heavier, the A170LL version of the same hinge takes doors up to 1,000 lbs. Both are aluminum geared continuous hinges, so the load spreads down the full height of the door instead of concentrating on three butt hinges, which is what stops a heavy leaf from sagging and dragging on the threshold.
2) What is the difference between a full mortise and a full surface continuous hinge, and which one do I need?
Full mortise is what the ABH A170 is: it mounts into the edge of the door and the rabbet of the frame, so the hinge is concealed when the door is closed and you get a clean edge. It needs a door and frame that can be prepped for it, which is the normal case on a new opening or an aluminum/hollow metal door in good condition. Full surface mounts on the face of the door and the face of the frame instead, which is what you use when the door edge or frame rabbet is chewed up from years of butt hinge repairs and you cannot get a clean mortise. For that situation, look at the Design Hardware Full Surface heavy duty geared hinge, or the offset full surface version where the frame face is out of plane.
3) What door inset does the ABH A170 hinge require?
1/8 inch. Every A170HD and A170LL configuration is built for a 1/8 inch door inset, meaning the gap between the door face and the frame face the hinge is designed around. Inset is not adjustable on a geared continuous hinge, so if your opening runs a different inset the A170 will not sit right. A 3/32 inch inset opening needs a hinge built for that dimension, such as the BEST 663HD heavy duty continuous hinge, and a 1/16 inch inset opening needs something like the NGP HD5700.
4) What lengths does the ABH A170 continuous hinge come in for a tall door?
Five stock lengths: 79, 83, 85, 95 and 120 inches. The 83 and 85 inch sizes cover the usual 7-foot opening, 95 inches handles an 8-foot door, and 120 inches is there for 10-foot leaves in lobbies and industrial openings. ABH also makes custom lengths for anything that does not land on a stock size. Continuous hinges are cut to the door, not the frame height, so measure the actual leaf before picking a size.
5) Does the ABH A170 continuous hinge meet Buy American requirements for a government or university job?
The A170 aluminum geared hinge is BAA qualified, so it meets Buy American Act requirements for federally funded and institutional work. That is the reason it shows up on public school, municipal and university door schedules; ABH holds a spec on file for Auburn University for this hinge. If your submittal has a BAA line item, this one clears it.
6) For a lead-lined x-ray room door, can I use a standard heavy duty continuous hinge?
Use the lead-lined variant. The ABH A170LL is the LL configuration built for lead-lined doors up to 1,000 lbs, where the standard A170HD carries 450 lbs. A lead-lined door of the same size weighs far more than a hollow metal one, so the heavy duty peers here - the Design Hardware FMHD full mortise and FSHD full surface geared hinges, and the BEST 663HD - are rated heavy duty for conventional doors rather than for a lead core. Order the A170LL by selecting the lead-lined option in the length and finish you need.
7) I need a fire rated continuous hinge for a 90 minute opening - what should I use instead of the ABH A170HD?
Use the BEST 663HD, a heavy duty continuous hinge carrying a 90 minute UL fire rating and cut for 3/32 inch inset doors. For a surface applied version of the same rating, the BEST 664HD is a full surface continuous geared hinge with a 90-minute UL fire rating. On the NGP side, the HD1100A concealed geared hinge and the HD5700 full surface geared hinge both carry a 10C fire rating, 90 minute on hollow metal. Match the mounting type to the door and frame condition you have: 663HD mortises in, 664HD and HD5700 apply to the face.
8) What is the closest full mortise continuous geared hinge equivalent to the ABH A170HD?
The Design Hardware FMHD is the nearest match: a heavy duty full mortise continuous geared hinge, the same mounting type and duty level as the A170HD, which is a full mortise heavy duty geared hinge rated to 450 lb door weight. The Pemko FM-RG Series is another full mortise geared option, an aluminum raised geared hinge with 180-degree swing built to Grade 1. Both mortise into the door edge and frame the same way the A170HD does, so the door prep concept carries over; confirm the leaf length against the door height you are hanging.
9) The door edge and frame will not take a mortise - what continuous hinge works instead of a full mortise one?
Go to a surface applied geared hinge. The Design Hardware FSHD is a heavy duty full surface continuous geared hinge and the FSOHD is the heavy duty full surface offset version for openings where the door must clear an obstruction on the swing side. The BEST 664HD is a full surface heavy duty geared hinge as well, with a 90-minute UL fire rating. The NGP HD5400A is a half surface geared hinge in aluminum alloy, mortised on one leaf and surface applied on the other, which suits a door that can be machined when the frame cannot. All of these avoid the door-edge and frame mortise the ABH A170HD full mortise design requires.
10) My spec calls out a Grade 1 continuous geared hinge - which ones meet that?
Four in the comparable group are built to Grade 1: the Pemko CFM84SLF-HD1, an 84 inch full mortise short leaf flush heavy duty hinge; the Pemko FM-RG Series aluminum full mortise raised geared hinge with 180-degree swing; the Pemko FM-SLF short leaf flush geared hinge for 1-3/8 inch doors; and the Pemko DSH1000 anti-barricade hinge. If the job is a federal or publicly funded project, note that the ABH A170HD is BAA qualified for Buy American Act requirements, which is a separate line item on most institutional specs from the grade call.
11) What continuous hinge should I specify for a behavioral health or detention door where a resident could barricade the door?
The Pemko DSH1000 is the anti-barricade hinge in this group, a Grade 1 continuous hinge with 100-degree bidirectional operation, meaning the door can be swung the other way to gain entry if the normal swing is blocked. That bidirectional function is specific to it - the ABH A170HD is a conventional full mortise gear hinge rated to 450 lb door weight and does not reverse swing. Specify the DSH1000 where the opening has a life-safety access requirement, and the A170HD where the concern is door weight and traffic.
12) Does the door inset dimension have to match when I swap continuous hinge brands?
Yes, the inset is a hard match. The ABH A170HD is built to a 1/8 inch door inset across its sizes. The BEST 663HD is cut for 3/32 inch inset doors and the NGP HD5700 is a 1/16 inch door inset model for 1-3/4 inch to 2-1/4 inch doors. Those are three different clearances between door edge and frame rabbet, and a hinge built for one will not gear correctly in the other. Measure the existing inset at the hinge edge before ordering any of them.
13) My doors are taller than 84 inches - which continuous hinges cover that height?
The ABH A170HD is made in 79 inch, 83 inch, 85 inch, 95 inch and 120 inch standard lengths with custom sizes available, so it covers tall openings directly. Among the alternatives, the Pemko CFM84SLF-HD1 is an 84 inch hinge and the NGP HD1100A and HD5400A are 83 inch, all of which stop short of a 95 or 120 inch leaf. For a tall storefront or an oversized entry door, the longer A170HD lengths are the ones to size against.
14) Does the ABH A170 hinge come with screws, or do I need to order fasteners separately?
Fasteners are included: 12-24 x 3/4 inch undercut self drilling, thread forming tek machine screws. Self drilling and thread forming means you are not pre-tapping the door edge or frame on hollow metal and aluminum, which is most of the labor on a continuous hinge install. Nothing else is needed to hang the hinge itself.
15) Should I replace failed butt hinges on a high-traffic door with a continuous geared hinge?
That is the usual reason to buy one. Butt hinges concentrate the whole leaf weight on three or four points, and on a high-traffic commercial opening the top hinge screws pull out of the frame and the door starts to sag and bind. A continuous geared hinge like the A170 runs the full height of the door and distributes that load along the entire edge, which is why it is specified for offices, schools, hospitals, government buildings, warehouses and multi-tenant residential. Since this is the full mortise version, the door edge and frame rabbet have to be in good enough shape to prep; if the existing butt hinge cutouts have wrecked them, go to a full surface hinge instead.
16) What is a Grade 1 alternative to the ABH A170 full mortise continuous hinge?
Pemko makes two full mortise geared hinges we carry that are stated Grade 1: the FM-RG Series aluminum raised geared hinge with a 180-degree swing, and the short leaf flush FM-SLF for 1-3/8 inch doors. There is also the Pemko 84 inch full mortise short leaf flush heavy duty Grade 1. Which one you take depends on the opening: raised geared clears an offset frame condition, short leaf flush is for thinner doors. All are full mortise like the A170, so they mount the same way.
17) Do I have to specify handing when ordering an ABH A170 continuous hinge?
No. Geared continuous hinges are non-handed, so one A170 covers a left or right hand opening. What you do have to specify is the length (79, 83, 85, 95 or 120 inches, or a custom cut), the finish, and whether the door is lead lined. Get the length and inset right and handing takes care of itself.
18) Is the ABH A170 hinge suitable for an exterior aluminum entrance door?
It is. The A170 is an aluminum geared hinge, so it does not rust the way a plated steel butt hinge does on an exterior opening, and clear anodized or dark bronze matches typical storefront framing. It is a commercial-rated hinge built for a 450 lb leaf, which covers most full-height glass entrance doors. Confirm the opening runs a 1/8 inch door inset, since that is what the hinge is cut for.
19) Is there a lighter duty continuous hinge if my door does not need the ABH A170HD heavy duty rating?
Yes. The BEST 641 is a steel full mortise standard duty continuous hinge with hospital tips, listed at medium duty, and the BEST 651 is the stainless steel full mortise version, also medium duty, with hospital tips. Both mount full mortise like the ABH A170HD, so the prep approach is the same, but the A170HD is the heavy duty gear hinge rated to 450 lb door weight. The hospital tips on the 641 and 651 give a sloped end cap that sheds debris, which is often specified in healthcare corridors.
20) Will a Pemko FM-SLF short leaf flush hinge substitute for the ABH A170HD on my doors?
Not on the same door. The Pemko FM-SLF is a short leaf flush continuous geared hinge for 1-3/8 inch doors, a thinner door than the heavy commercial leaf the ABH A170HD is built around, and the A170HD is a full mortise hinge carrying 450 lb of door weight with an LL variant for lead-lined doors to 1,000 lbs. Both are full mortise geared hinges, so they look similar on a submittal; the door thickness and the weight the leaf carries are what separate them. For a heavier full mortise Pemko, the CFM84SLF-HD1 is the 84 inch heavy duty Grade 1 short leaf flush model.
21) I need a stainless steel continuous hinge, not aluminum - what are my options?
The BEST 651 is the stainless steel choice, a full mortise continuous hinge with hospital tips at medium duty, and the BEST 641 is the steel standard duty version, also medium duty full mortise with hospital tips. The ABH A170HD is aluminum gear hinge construction rated to 450 lb door weight, and the NGP HD5400A is aluminum alloy in a half surface configuration. Pick stainless where washdown, coastal exposure, or a clinical cleaning regime is driving the material call.
22) What finishes does the ABH A170 aluminum continuous hinge come in to match my storefront?
Three: clear anodized aluminum, dark bronze, and black. Clear anodized is the match for standard mill-finish aluminum storefront, dark bronze pairs with bronze anodized entrances, and black suits painted hollow metal and darker curtain wall. All three are offered in every stock length and in both the standard and lead-lined builds, so finish never limits which size you can get.
