ABH A213 HD079 C – Frequently Asked Questions

1) How much door weight will the ABH A213HD continuous gear hinge carry?
The A213HD is rated for doors up to 450 lbs and up to 48 inches wide. That covers heavy hollow metal and lead-lined leaves that eat butt hinges. The load rides the full height of the leaf instead of three points, so the door doesn't sag or bind the way a butt-hung door does once the top hinge starts pulling.
2) What is the difference between a half surface continuous hinge and a full mortise or full surface one?
Half surface means one leaf mortises into the frame and the other surface-applies to the door face. The A213HD is the half surface configuration, so no mortising of the door is needed and the door leaf covers old butt hinge cut-outs. Full mortise buries both leaves in the frame rabbet and the door edge, which is cleaner but means prepping both. Full surface applies both leaves to the face, which is what you use when neither the door nor frame can be machined. ZenSupply carries all three geometries: Design Hardware FMHD is the full mortise heavy duty, FSHD is the full surface, and FSOHD is the full surface offset.
3) Can I use the ABH A213HD on a 90 minute fire rated door?
Yes on metal. The A213HD is approved for metal swinging fire doors rated up to 90 minutes, and for wood swinging fire doors up to 60 minutes. If the opening is a 90 minute wood door, this hinge is not the one; look at a hinge carrying a 90 minute wood label.
4) Is the ABH A213HD BHMA Grade 1?
Yes, the A213HD meets BHMA A156.25 Grade 1. That is the top durability tier under the continuous hinge standard and is what a spec on a school, hospital or government opening usually calls for. Among the alternatives ZenSupply stocks, the Pemko FM-RG Series and the Pemko 84 inch full mortise short leaf flush are also Grade 1; the NGP HD1100A concealed geared hinge is listed as Grade 3.
5) Will the ABH A213HD work on a butt hung door or only center hung?
Center hung. Every A213HD ordered here is the center hung door inset configuration, built with extended finger guard reach for that geometry. If your leaf hangs on a different inset, the gear will not line up right and you want a different model in the aluminum geared range.
6) I keep replacing butt hinges on a high traffic door. Is a continuous geared hinge worth switching to?
That is the usual reason people move to one. A continuous hinge spreads the load along the full door and frame rather than concentrating it at three or four points, so the binding and sagging that kills butt hinges stops. It also closes the gap between door and frame, which removes the pry point at the hinge edge. On the A213HD the half surface design means you do not machine the door, and the surface leaf hides the old butt cut-outs, so the retrofit does not need a new door.
7) My door is full surface, not half surface - what continuous geared hinge do I order in place of the A213HD?
The ABH A213HD is a half surface hinge, so on a full surface application move to a full surface geared hinge. The BEST 664HD is a heavy duty full surface continuous geared hinge with a 90 minute UL fire rating. The Design Hardware FSHD is a heavy duty full surface continuous geared hinge, and the FSOHD is the heavy duty full surface offset version. The NGP HD5700 is an 83 inch full surface continuous geared hinge with 1/16 inch door inset for 1-3/4 to 2-1/4 inch doors, 10C fire rated 90 minutes on hollow metal. The A213HD itself is fire rated to 90 minutes on metal doors and 60 minutes on wood.
8) The door and frame are already mortised for a full mortise continuous hinge - what should I use instead of the A213HD?
Go to a full mortise geared hinge rather than the half surface ABH A213HD, which is surface applied and needs no mortising of door or frame. The Design Hardware FMHD is a heavy duty full mortise continuous geared hinge, matching the A213HD on duty level. The Pemko FM-RG Series is a Grade 1 aluminum full mortise raised geared continuous hinge with a 180 degree swing, and the Pemko CFM84SLF-HD1 is an 84 inch full mortise short leaf flush heavy duty Grade 1 hinge. The A213HD is BHMA Grade 1 as well, so a Grade 1 full mortise peer holds the same certification level on the spec.
9) Is a BEST 641 or 651 continuous hinge equivalent to the ABH A213HD?
No. The BEST 641 steel full mortise continuous hinge with hospital tips and the BEST 651 stainless steel full mortise continuous hinge with hospital tips are both medium duty. The ABH A213HD is a heavy duty half surface hinge rated for doors up to 450 lbs and 48 inches wide, so the BEST 641 and 651 sit at a different duty level and mount full mortise rather than surface applied. For a heavy duty match within the BEST line, look at the 663HD or 664HD instead.
10) Does the ABH A213HD half surface hinge come with screws, and what size are they?
Fasteners are included: 12-24 x 3/4 inch undercut self drilling, thread forming tek machine screws. Self drilling means you are not tapping the frame or door face first on hollow metal. Order nothing extra for fastening.
11) What finishes does the ABH A213HD aluminum continuous hinge come in?
Three: clear anodized aluminum, dark bronze, and black. All three are offered in each of the five standard lengths, so a building standardizing on dark bronze storefront or black frames can match across 79, 83, 85, 95 and 120 inch openings. The finish is applied by post-machining anodization, so cut edges and machined areas match the rest of the leaf.
12) Is the ABH A213HD Buy American compliant for a federal job?
Yes, the A213HD is BAA qualified, which is what a government or municipal submittal is usually asking for. It is a commercial-duty product, not a residential line.
13) Do I need a special door prep or template to install the ABH A213HD?
No door machining. It surface-applies to the door face with self drilling 12-24 x 3/4 inch tek screws, so the crew is drilling through the leaf rather than routing the door edge. Standard length hinges use templated hole patterns, which is what makes a run of identical openings repeatable across a building.
14) My door is 1-3/8 inch thick - is the ABH A213HD the right continuous hinge?
The ABH A213HD is a half surface geared hinge built for center hung doors up to 48 inches wide and 450 lbs, in lengths of 79, 83, 85, 95 and 120 inches. For a thinner 1-3/8 inch door, the Pemko FM-SLF is a short leaf flush continuous geared hinge specified for 1-3/8 inch doors with Grade 1 construction. On thicker leaves, the NGP HD5700 is sized for 1-3/4 to 2-1/4 inch doors.
15) What continuous hinge handles a barricade risk on a school door instead of the A213HD?
The Pemko DSH1000 is an anti-barricade continuous hinge with 100 degree bidirectional operation, Grade 1, which lets a door swing both directions so it cannot be blocked shut from inside. The ABH A213HD is a standard half surface geared hinge, BHMA Grade 1, that eliminates gaps between door and frame to resist prying and carries doors to 450 lbs. The two solve different problems: the DSH1000 addresses bidirectional egress, the A213HD addresses load and alignment on a heavy swinging door.
16) Is a concealed continuous hinge a substitute for the ABH A213HD on the same opening?
They mount differently. The NGP HD1100A is a concealed continuous geared hinge in an 83 inch length, which sits hidden within the door and frame. The ABH A213HD is surface applied on the half surface side, requiring no mortising of door or frame and covering old butt hinge cut outs. On a retrofit where the old butt hinge preps are still open, that surface application is the difference; a concealed hinge does not conceal those cut outs.
17) Is the ABH A213HD a handed hinge, do I need to specify left or right?
Length, finish and door inset are the three things you specify on the A213HD: 79, 83, 85, 95 or 120 inches, clear anodized, dark bronze or black, in the center hung configuration. There is no separate keying or lock function to call out on a continuous hinge, and no cylinder to match.
18) Does hospital tip styling on a continuous hinge change what I can substitute for the A213HD?
The BEST 641 and BEST 651 are the hospital tip options, both full mortise continuous hinges with hospital tips, the 641 in steel and the 651 in stainless steel, and both medium duty. The ABH A213HD is a half surface anodized aluminum geared hinge, heavy duty at 450 lbs, offered in black, clear anodized aluminum and dark bronze. If the hospital tip detail is what is being specified for the opening, the A213HD does not replace it, and the reverse holds where the 450 lb heavy duty capacity is the requirement.
19) What is the difference between the Design Hardware FSHD and FSOHD if I am cross shopping against the ABH A213HD?
The Design Hardware FSHD is a heavy duty full surface continuous geared hinge and the FSOHD is the heavy duty full surface offset version, the offset being for openings where the door must clear an obstruction at the frame. Both are full surface; the ABH A213HD is half surface, so it mounts on a different face configuration than either. All three are heavy duty geared hinges, with the A213HD rated to 450 lbs and BHMA 156.25 Grade 1.
