ABH A270HDC079 – Frequently Asked Questions

1) Will an ABH A260 or A270 continuous hinge work on a 2 inch thick door?
Yes. The ABH aluminum continuous gear hinges in the A260 and A270 models are built for 2 inch thick doors, full mortise, up to 48 inches wide and 450 lbs. Most commercial openings run 1-3/4 inches, so check the actual leaf thickness before you order these; a 2 inch door is usually a lead-lined, acoustic, or heavy custom leaf.
2) What is the difference between the ABH A260 and A270 continuous gear hinges?
Inset. The A260 is cut for a 3/32 inch door inset, meaning the door face sits back from the frame face by that amount. The A270 has no inset, for a door that sits flush. Pick by measuring the existing opening, because the wrong inset will not close the gear correctly. Both are ordered on the same door inset option, either 3/32 inch or none.
3) Is the ABH continuous geared hinge fire rated, and for how long?
Yes. These ABH aluminum continuous gear hinges are approved for metal swinging fire doors up to 90 minutes and wood swinging fire doors up to 60 minutes. If your opening is a 90 minute wood door, this is not the hinge for it.
4) Do ABH make a continuous hinge for lead lined doors?
Yes. The ABH aluminum continuous gear hinge is ordered either as a standard unit or as a lead lined version, which is the LL variant of the A260 and A270. Lead lined X-ray room doors are heavy and often thicker than a normal leaf, which is why the 2 inch, 450 lb version of this hinge exists. Specify the lead lined option at order time; it is not something you can add later.
5) Is the ABH continuous hinge BHMA Grade 1?
Yes, certified to BHMA A156.25 Grade 1, which is the top durability tier for continuous hinges and the grade most institutional and government specs call for. If you are standardizing a facility on Grade 1 hinges, this qualifies.
6) What is the closest full mortise continuous geared hinge equivalent to the ABH A260 and A270 from another manufacturer?
The ABH A260 and A270 are aluminum full mortise continuous gear hinges rated for 450 lb doors. The closest full mortise geared equivalents from other lines are the Design Hardware FMHD Full Mortise heavy duty continuous geared hinge and the Pemko FM-RG Series, an aluminum full mortise raised geared continuous hinge with 180 degree swing. Both mount into the same full mortise prep between door edge and frame rabbet, so either drops into the same opening the A260 or A270 was specified for.
7) The door edge is too damaged to take a mortised hinge leaf. What continuous hinge should be used instead of the ABH A260?
A full surface continuous geared hinge mounts on the face of the door and frame rather than into the door edge, which leaves a damaged or previously butchered edge out of the load path. The Design Hardware FSHD Full Surface heavy duty continuous geared hinge, the BEST 664HD full surface continuous geared hinge with a 90 minute UL fire rating, and the NGP HD5700 83 inch full surface continuous geared hinge with 1/16 inch door inset for 1-3/4 inch to 2-1/4 inch doors are all full surface. The ABH A260 and A270 are full mortise, so they need a sound door edge and frame rabbet.
8) Which continuous hinge matches the 3/32 inch door inset that the ABH A260 uses?
The ABH line offers a 3/32 inch door inset version and a no inset version. On the inset side, the BEST 663HD is a heavy duty continuous hinge described for 3/32 inch inset doors and carries a 90 minute UL fire rating, so it addresses the same inset condition. The NGP HD5700 is built around a 1/16 inch door inset instead, which is a different gap dimension and not a match for a 3/32 inch inset opening.
9) For a facility standardizing on BHMA Grade 1 continuous hinges, which alternates to the ABH A260 hold Grade 1?
The ABH A260 and A270 are BHMA 156.25 Grade 1 certified. Among other full mortise geared hinges, the Pemko FM-RG Series is Grade 1, the Pemko CFM84SLF-HD1 84 inch full mortise short leaf flush heavy duty hinge is Grade 1, and the Pemko FM-SLF short leaf flush geared hinge for 1-3/8 inch doors is Grade 1. The NGP HD1100A concealed continuous geared hinge is Grade 3, so it sits at a different certification level for a Grade 1 spec.
10) Which alternates to the ABH A260 carry a 90 minute fire rating for hollow metal doors?
The ABH A260 and A270 are fire rated for metal swinging fire doors up to 90 minutes and wood swinging fire doors up to 60 minutes. Among other geared hinges, the BEST 663HD and BEST 664HD each carry a 90 minute UL fire rating, and the NGP HD1100A, NGP HD5400A and NGP HD5700 are each 10C fire rated for 90 minutes on hollow metal. Note the mounting differs across those: 663HD is for 3/32 inch inset doors, 664HD and HD5700 are full surface, and HD5400A is half surface.
11) For a lead-lined door in a radiology suite, which continuous hinge is specified?
The ABH A260 and A270 are offered in a lead-lined door version alongside the standard version, and they are rated for 450 lb doors, which is the range a lead-lined leaf lands in. Among the other geared hinges, the Design Hardware FMHD full mortise and the BEST 663HD are listed at heavy duty, but the lead-lined designation is specific to the ABH build.
12) Is a continuous geared hinge worth it over three butt hinges on a high traffic door?
On a door that gets abused, yes. A continuous gear hinge runs the full height of the leaf and spreads the load along the whole edge rather than at three points, which is what stops the sag and bind that pulls a heavy door out of alignment. It also closes the gap between door and frame the length of the opening, so there is nothing to pry at the hinge side. That is why they go on school, hospital, and lobby entrances that see thousands of cycles.
13) Are the mounting screws included with the ABH continuous hinge?
Fasteners come with it: 12-24 x 3/4 inch undercut self drilling, thread forming tek machine screws. They drill and form their own threads into hollow metal, so you are not tapping the frame on site. On a wood door you will want to confirm the substrate takes a machine screw of that size.
14) Does the ABH continuous hinge meet Buy American requirements for a government job?
It is BAA qualified, so it can go on a Buy American Act job. That plus Grade 1 certification is usually what a municipal or federal spec is asking for on a hinge line item.
15) What else could I buy instead of the ABH A260 full mortise continuous hinge?
For a like for like full mortise geared hinge, the Design Hardware Full Mortise heavy duty continuous geared hinge is the closest heavy duty equivalent, and the Pemko FM-RG Series is a Grade 1 aluminum full mortise raised geared hinge. On the BEST side, the 663HD is a heavy duty hinge cut for a 3/32 inch inset door, same inset as the ABH A260, and it is 90 minute UL fire rated. Which one you pick usually comes down to what the rest of the building is already standardized on.
16) Will a continuous geared hinge cover the old butt hinge cutouts in my frame?
On a retrofit, yes. The hinge runs the full height of the opening, so it covers the existing butt hinge cut-outs on the hinge edge instead of leaving you patching and repainting the frame. That is one of the main reasons these get specified on door replacement work in occupied buildings.
17) Do I need to specify handing when I order an ABH continuous geared hinge?
No handing to call out. A continuous geared hinge is symmetrical along the door edge and works either hand, so the order comes down to four things: inset (3/32 inch for the A260, none for the A270), length, finish, and whether the door is lead lined. Get those four right and the part is right.
18) Is a steel or stainless continuous hinge a straight swap for an aluminum geared hinge on a wash down or corrosive area door?
The BEST 651 is a stainless steel full mortise continuous hinge with hospital tips, listed at medium duty, and the BEST 641 is the steel version at the same duty level. The ABH A260 and A270 are anodized aluminum geared hinges rated for 450 lb doors and BHMA Grade 1. The 641 and 651 are hinges with hospital tips rather than geared hinges, so the leaf profile, the load path along the door and the mounting hole pattern all differ from a geared aluminum hinge.
19) What continuous hinge should be used when the door has to clear a projection or trim that a full mortise hinge will not allow?
An offset continuous hinge swings the door away from the frame face so the leaf clears adjacent construction. The Design Hardware FSOHD is a full surface offset heavy duty continuous geared hinge built for that condition. The ABH A260 and A270 are full mortise and pivot on the door edge line, so they do not provide that offset. A half surface option, the NGP HD5400A 83 inch half surface continuous geared hinge in aluminum alloy, mounts one leaf to the door face and the other into the frame when only one side can be mortised.
20) Is the Pemko DSH1000 anti-barricade hinge an alternative to the ABH A260 on a behavioral health or detention opening?
The Pemko DSH1000 is a Grade 1 anti-barricade continuous hinge with 100 degree bidirectional operation, meaning the door can swing either direction so an occupant cannot barricade the opening. That is a distinct function. The ABH A260 and A270 are conventional single direction full mortise geared hinges rated for 450 lb doors, so they do not deliver bidirectional swing. On an opening where the anti-barricade requirement is on the drawing, the DSH1000 is the one that answers it.
21) Which continuous hinge is the match when the hinge has to be hidden with the door closed rather than showing an aluminum edge?
The NGP HD1100A is a concealed continuous geared hinge in an 83 inch length, described as heavy duty and listed at Grade 3, and it is 10C fire rated 90 minutes on hollow metal. The ABH A260 and A270 are exposed geared hinges finished in Clear Anodized Aluminum, Dark Bronze or Black, so the hinge edge reads as part of the door line rather than disappearing.
22) What finishes does the ABH aluminum continuous gear hinge come in?
Three: clear anodized aluminum, dark bronze, and black. Clear anodized is the default match for aluminum storefront and most hollow metal frames; dark bronze pairs with bronze anodized entrances, and black with a painted or black anodized system. If you are matching other openings in the same building, pull the finish off an existing hinge before ordering the run.
