ABH A505078-US32D – Frequently Asked Questions

1) Can an ABH A505 hinge cover the old butt hinge cutouts when I replace butts on a commercial door?
That is one of the main reasons to use it. The A505 is a flush mount full mortise hinge that needs no door inset, and it is surface applied over the hinge edge, so it covers existing butt hinge cut-outs without any new mortising. You are removing three or four butts and running one continuous hinge the height of the door instead, which also cures the sag and alignment problems that made the butts fail.
2) Is the ABH A505 Grade 1, and does it qualify for a federal Buy American job?
The A505 is certified to BHMA 156.25 Grade 1, the top grade for continuous hinges, and it is BAA qualified, so it can be used on Buy American Act federal and municipal work. That combination is what government and institutional specs usually call for on a continuous hinge.
3) My door is set into the frame with an inset. Will the ABH A505 work?
No. The A505 is built for no door inset, so it wants a flush condition at the hinge edge. For an inset door you need a hinge made for it: the BEST 663HD heavy duty continuous hinge is built for 3/32 inch inset doors, and the NGP HD5700 full surface geared hinge carries a 1/16 inch door inset for 1-3/4 to 2-1/4 inch doors. Measure the inset at the hinge edge before you order either way.
4) Can I use the ABH A505 if I cannot mortise the frame, or the door is already hung?
The A505 is a full mortise hinge, so it mounts between the door edge and the frame rabbet. If the frame will not take that, use a full surface hinge instead, which applies to the face of the door and frame: ZenSupply carries the Design Hardware FSHD full surface and FSOHD full surface offset heavy duty geared hinges, the BEST 664HD full surface geared hinge with a 90 minute UL fire rating, and the NGP HD5400A half surface geared hinge. Half and full surface are the retrofit answers when the existing frame prep will not change.
5) My opening is a 90 minute fire rated hollow metal door - which continuous hinges are rated for it?
The ABH A505 is certified for 90 minutes on hollow metal and composite core wood fire doors and 3 hours on hollow metal doors, with 20 minutes on wood doors. Among other continuous hinges, BEST 663HD and BEST 664HD are both 90 minute UL fire rated heavy duty hinges, and NGP lists 10C fire rated 90 minute on hollow metal for the HD1100A, HD5400A and HD5700. Confirm the rating against the door assembly listing before you order.
6) What is the closest full mortise heavy duty continuous hinge to the ABH A505 if I need a different brand?
The Pemko CFM84SLF-HD1 is the nearest full mortise heavy duty equivalent. It is an 84 inch full mortise short leaf flush continuous hinge rated Grade 1, so it matches the A505 on mounting style, duty level and grade certification. The A505 is a stainless steel pin and barrel hinge carrying doors up to 600 lbs with a door edge guard on both faces of the door; the Pemko is a short leaf flush geared design. Design Hardware FMHD is the other full mortise heavy duty geared option if you want a geared barrel instead of a pin and barrel.
7) I need a Grade 1 continuous hinge for a spec that calls out Grade 1 - which options meet that besides the ABH A505?
The A505 is BHMA 156.25 Grade 1 certified. Among the other continuous hinges, Pemko lists Grade 1 on the CFM84SLF-HD1 full mortise short leaf flush, the FM-RG series aluminum full mortise raised geared hinge with 180 degree swing, the FM-SLF short leaf flush geared hinge for 1-3/8 inch doors, and the DSH1000 anti-barricade hinge. The NGP HD1100A concealed geared hinge is Grade 3, so it will not satisfy a Grade 1 callout.
8) I need the hinge line covered for security on a behavioral health or detention opening - does the ABH A505 do that or is there a purpose-built hinge?
The A505 puts a door edge guard on both faces of the door, closing the gap between door and frame to resist prying, and it is a flush mount hinge with no exposed door inset. If the concern is a door being barricaded shut from inside, that is a different design problem: the Pemko DSH1000 is an anti-barricade continuous hinge with 100 degree bidirectional operation, rated Grade 1, so the door can be swung the other way to gain entry. Choose the A505 for prying resistance on a standard swing, the DSH1000 where the opening must reverse.
9) What does the door edge guard on the ABH A505 actually do for security?
The A505 carries a door edge guard on both faces of the door, which closes the gap between door and frame along the hinge edge. That removes the purchase point a pry bar needs and shields the hinge edge from tampering. It is why this model gets specified in schools, healthcare corridors and multi-tenant buildings where the hinge side has been attacked or abused. If you do not need the edge protection, ABH makes plain pin and barrel models without it.
10) Does the ABH A505 hinge come with screws, or do I need to buy fasteners?
Fasteners are included: 10-24 x 7/8 inch undercut, self-drilling, thread-forming tek machine screws in stainless steel for metal, plus #10 x 1-1/4 inch undercut wood screws in stainless steel. The tek screws are what let you hang it on a hollow metal frame without pre-tapping. Hole patterns are templated, so the drilling is consistent across every opening you do.
11) Pin and barrel versus geared continuous hinge, which should I use?
A pin and barrel hinge like the A505 runs a continuous pin through interlocking knuckles, which looks and behaves like a very long butt hinge and takes stainless construction well for wet or corrosive areas. Geared continuous hinges run a gear set under a cap and are the other common approach; ZenSupply carries them from Design Hardware (full mortise FMHD, full surface FSHD, full surface offset FSOHD) and Pemko (the FM-RG Series aluminum full mortise raised geared hinge, Grade 1). If your frame prep is full mortise and you want stainless rather than aluminum, the A505 is the pin and barrel answer.
12) I need a heavy duty continuous hinge but my door is only medium traffic. What are the lighter options?
The A505 is a 600 lb, Grade 1 stainless pin and barrel hinge, which is more hinge than a light interior office door needs. For medium duty work ZenSupply carries the BEST 641 in steel and the BEST 651 in stainless, both full mortise continuous hinges with hospital tips and both rated medium duty. Hospital tips are worth noting if the opening is in a healthcare corridor where nothing on the door can catch a sleeve or a gurney rail.
13) Is there an ABH A505 cross reference to another manufacturer's continuous hinge?
ABH publishes a cross reference chart for its stainless steel pin and barrel continuous hinges, which maps competitor models to the ABH equivalent. There is also a door clearance chart for working out how the hinge sits in the opening, and cut sheets for the A505 and the related A510, A515 and A515RB models. Those documents are the place to confirm a swap before you order.
14) Do I need the ABH A505 for an interior door that sees light traffic, or is there a lighter continuous hinge?
The A505 is the heavy duty answer, stainless steel pin and barrel carrying doors up to 600 lbs. Where the opening does not need that capacity, BEST offers medium duty full mortise continuous hinges with hospital tips: the 641 in steel and the 651 in stainless steel. Both mount full mortise like the A505, so the frame prep concept is the same; the difference is duty level and, on the 641, a steel rather than stainless leaf.
15) Is a geared continuous hinge the same thing as the ABH A505 pin and barrel hinge?
They are not the same construction. The A505 is a pin and barrel continuous hinge - a continuous knuckle and pin running the height of the door, in stainless steel, with a door edge guard on both faces. A geared continuous hinge runs meshed gear teeth inside a cap along the hinge line instead; Design Hardware FMHD, BEST 664HD, NGP HD1100A and the Pemko FM-RG series are all geared designs. Both types are continuous hinges and both are ordered by door height, but the leaf profile, cap and hole pattern differ, so a geared hinge is not a drop-in for pin and barrel prep.
16) Are there continuous hinge options that hide the hinge when the door is closed, unlike the ABH A505?
The A505 is a flush mount pin and barrel hinge; the barrel runs the height of the opening on the hinge edge with a door edge guard on both faces. For a concealed look, the NGP HD1100A is a concealed continuous geared hinge in 83 inch length, described as heavy duty and rated Grade 3, 10C fire rated 90 minute on hollow metal. The NGP HD5400A is a half surface geared hinge in aluminum alloy at 83 inches with the same 10C 90 minute hollow metal fire rating, which sits between concealed and full surface mounting.
17) I want a stainless steel continuous hinge, not aluminum - which ones are stainless?
The ABH A505 is a stainless steel pin and barrel hinge and ships with stainless fasteners, 10-24 x 7/8 inch undercut self-drilling tek machine screws and #10 x 1-1/4 inch undercut wood screws. Among the other continuous hinges, the BEST 651 full mortise hinge with hospital tips is stainless steel at a medium duty level. The BEST 641 is steel, the Pemko FM-RG series is aluminum, and the NGP HD5400A is aluminum alloy, so if the environment is driving the material choice those are a different specification.
18) I need a full 180 degree swing so the door lays back flat against the wall - will the ABH A505 do that or should I look at another hinge?
For an opening specified around a 180 degree swing, the Pemko FM-RG series aluminum full mortise raised geared continuous hinge is listed with 180 degree swing and Grade 1 construction. The ABH A505 is the choice when the requirement is a stainless steel pin and barrel hinge carrying up to 600 lbs with a door edge guard on both faces; the FM-RG is aluminum and geared, so the two are different construction even though both mount full mortise.
19) What finish does the ABH A505 come in, and will it match my other stainless hardware?
One finish across every length: 630, satin stainless steel. That is the standard commercial satin stainless finish, so it lines up with 630 push plates, exit devices and levers already on the openings. If the rest of the building is in 626 satin chrome, the hinge will read slightly brighter and cooler than the brass-base hardware next to it.
20) Is the ABH A505 suitable for residential doors?
It is a commercial hinge. The A505 is rated commercial, built to 600 lbs and BHMA Grade 1, which is aimed at office buildings, schools, hospitals, retail, warehouses, multi-tenant residential and government buildings. On a house door it will work mechanically but you are paying for capacity the opening will never use. Multi-family and apartment corridor doors are where it earns its keep on the residential side.
