ABH A210 HD C 079 – Frequently Asked Questions

1) Will the ABH A210HD swing clear hinge give me a full clear opening for a hospital bed or wheelchair?
That is exactly what the swing clear geometry is for. The A210HD is a full surface swing clear continuous gear hinge, so when the door is opened to 90 degrees the door leaf swings clear of the opening instead of sitting in it. You get back the width the door thickness would otherwise steal, which is what patient rooms, corridors with gurney traffic, and tight ADA-constrained openings need. It mounts on the surface of the door and frame, so no mortising of either.
2) How heavy a door can an ABH A210HD continuous hinge carry?
Up to 450 lbs, and up to 48 inches of door width. That covers most hollow metal and heavy wood commercial leafs, including lead-lined and oversized doors that tear butt hinges out. The continuous gear runs the full height of the door, so the load is spread down the whole edge rather than concentrated at three or four hinge points, which is why continuous hinges stop the sag and drag that make doors bind at the top corner.
3) Is the ABH A210HD fire rated, and for how long?
Fire rated both ways, with different numbers depending on the door. Metal swinging fire doors are covered up to 90 minutes; wood swinging fire doors up to 60 minutes. If your opening is a wood door on a 90 minute label, this hinge is not the one to spec. It also carries BHMA 156.25 Grade 1 certification, the top durability tier for continuous hinges.
4) Can I put a continuous hinge over the old butt hinge cutouts without replacing the door or frame?
Yes, and that is the main reason full surface is chosen on a retrofit. The A210HD is surface applied to the face of the door and frame, so nothing has to be mortised, and the hinge leaf covers the existing butt hinge cut-outs in both the door and the jamb. That keeps a beaten-up frame in service instead of pulling it. If your door and frame are already prepped and you want the hinge concealed in the mortise instead, a full mortise geared hinge like the Design Hardware FMHD heavy duty is the version to look at.
5) I need a continuous hinge for a 1-3/8 inch door - will the ABH A210HD work?
The A210HD is a heavy duty hinge rated for doors up to 450 lbs and 48 inch width, sized for heavier commercial leaves. For a 1-3/8 inch door, the Pemko FM-SLF short leaf flush continuous geared hinge is built specifically for 1-3/8 inch doors with Grade 1 construction. That one is a full mortise short leaf design rather than the A210HD's surface application, so the door and frame need to be prepped accordingly.
6) What is the closest equivalent to the ABH A210HD full surface continuous geared hinge from another brand?
The BEST 664HD is a full surface continuous geared hinge in a heavy duty configuration with a 90-minute UL fire rating, which matches the A210HD's full surface mounting approach and its 90-minute rating on metal swinging fire doors. The Design Hardware FSHD is also a full surface heavy duty continuous geared hinge. The distinction to check before ordering is the swing clear geometry: the A210HD is a swing clear hinge, which throws the door leaf clear of the opening when the door is open, and a standard full surface hinge does not.
7) The door frame is already mortised for a continuous hinge - what should I use instead of a full surface hinge?
Use a full mortise continuous geared hinge. The Design Hardware FMHD is a full mortise heavy duty continuous geared hinge, and the Pemko FM-RG series is a Grade 1 aluminum full mortise raised geared continuous hinge with 180-degree swing. The ABH A210HD is a full surface hinge, applied to the face of the door and frame with no mortising required, which is what lets it cover old butt hinge cut-outs but also means it sits on the surface rather than in an existing mortise pocket.
8) The door has a 3/32 inch inset - can I still use the ABH A210HD?
The A210HD is ordered with a door inset of None across all of its lengths and finishes. For an inset opening, the BEST 663HD is a heavy duty continuous hinge built for 3/32 inch inset doors with a 90 minute UL fire rating, and the NGP HD5700 is an 83 inch full surface continuous geared hinge with a 1/16 inch door inset for 1-3/4 inch to 2-1/4 inch doors. Measure the inset at the hinge edge before ordering, since the inset dimension is what determines which of these lines up.
9) I need the hinge hidden when the door is closed - is the ABH A210HD the right choice?
No. The A210HD is a full surface hinge, applied to the face of the door and frame, so the hinge body is visible. For a concealed application the NGP HD1100A is a concealed continuous geared hinge in an 83 inch length, 10C fire rated 90 minute on hollow metal. That concealed mounting also means the hinge will not cover existing butt hinge cut-outs the way the surface applied A210HD does.
10) Which continuous hinge should I spec for a behavioral health room where the door must open even if it is blocked?
The Pemko DSH1000 is an anti-barricade continuous hinge with 100-degree bidirectional operation and Grade 1 construction, so the door can be swung from either direction. The ABH A210HD is a swing clear hinge for conventional single-direction commercial openings and does not provide bidirectional operation, so for an anti-barricade requirement the DSH1000 is the one that meets it.
11) What screws come with the ABH A210HD, and do I need to tap the frame?
Fasteners are in the box for both sides. The frame side uses 12-24 x 3/4 inch undercut self drilling, thread forming tek machine screws, so they cut their own threads into hollow metal and you do not need to drill and tap ahead of time. The door side uses 1/4-20 sex bolts and shoulder bolts, which clamp through the door rather than relying on threads in a thin skin. For a wood or mineral core door that through-bolting is what keeps the hinge on under load.
12) Does the ABH A210HD qualify for a federal job with Buy American requirements?
It is BAA qualified, so it can be specified on federal and municipal work carrying Buy American Act provisions. Paired with the BHMA 156.25 Grade 1 certification and the fire rating, that is the documentation package a government or institutional spec normally asks for on a continuous hinge.
13) Should I use a swing clear continuous hinge or a standard full surface one?
It comes down to whether you need the opening width back. A swing clear hinge like the A210HD throws the door out of the opening when it swings, which matters for gurney and wheelchair clearance and for narrow existing frames you cannot widen. If clearance is not the problem and you just want a heavy duty full surface geared hinge, a standard full surface unit such as the BEST 664HD or the Design Hardware FSHD does the structural job without the offset geometry. For doors set into the frame with an inset, the Design Hardware FSOHD full surface offset is the version built for that condition.
14) What finishes does the ABH A210HD swing clear hinge come in, and do all lengths come in all of them?
Three finishes: clear anodized aluminum, dark bronze, and black. Every one of the five lengths (79, 83, 85, 95 and 120 inch) is offered in all three, so you can standardize a finish across a whole building without worrying about door height. The anodizing is applied after machining, which means the cut edges and screw holes are finished too rather than showing bare aluminum.
15) Will a continuous hinge stop my heavy commercial door from sagging and dragging on the floor?
That is the core fix. Because the gear runs the entire height of the door, the A210HD distributes the weight along the full door and frame instead of loading three butt hinges, so the door does not settle out of square over time. On a 450 lb leaf that is the difference between a door that latches for years and one you keep coming back to adjust. It also closes the gap between door and frame along the hinge edge, which removes the leverage point someone would pry at.
16) What is the ABH equivalent to a BEST or NGP continuous geared hinge for a full surface application?
For a heavy duty full surface geared hinge, the A210HD sits alongside the BEST 664HD and the NGP HD5700. The difference to check is the door condition: the NGP HD5700 is built for a 1/16 inch door inset and 1-3/4 to 2-1/4 inch doors, while the A210HD is a swing clear unit intended to clear the opening rather than sit inside it. Pemko's aluminum geared options are full mortise instead, so they need the door and frame machined.
17) For a healthcare corridor door, is the ABH A210HD or a hospital tip continuous hinge the better fit?
They solve different problems. Hospital tips, as on the BEST 641 steel full mortise hinge and the BEST 651 stainless steel hinge, angle the hinge ends so gurney rails, IV poles and clothing do not catch. The A210HD swing clear design instead moves the door leaf out of the opening when the door is open, recovering the full clear width for a bed or cart to pass. On a heavy corridor door up to 450 lbs where clear width is the constraint, the A210HD addresses the width; where the concern is snagging at the hinge, a hospital tip hinge addresses that.
18) Is there a lighter duty continuous hinge if the door does not weigh anywhere near 450 lbs?
The BEST 641 is a steel full mortise standard duty continuous hinge with hospital tips at a medium duty level, and the BEST 651 is a stainless steel full mortise continuous hinge with hospital tips, also medium duty. The ABH A210HD is built for doors up to 450 lbs and 48 inch width in heavy duty aluminum, so on a lighter interior door the medium duty options cover the same continuous hinge function. Note both of those BEST hinges are full mortise, so they need a mortised door and frame rather than the A210HD's surface application.
19) Which continuous hinges besides the ABH A210HD carry a Grade 1 rating for a facility standardization spec?
The A210HD meets BHMA 156.25 Grade 1. Among comparable continuous 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 mounting types differ, so match the Grade 1 line to the door prep you actually have.
20) What is the difference between the ABH A210HD and a half surface continuous geared hinge?
A full surface hinge such as the A210HD mounts to the face of both the door and the frame, so no mortising is needed on either. A half surface hinge mounts to the face of the door but into the frame rebate: the NGP HD5400A is an 83 inch half surface continuous geared hinge in aluminum alloy, 10C fire rated 90 minute on hollow metal. Half surface is the choice when the frame prep is already there and only the door face is available.
21) The door and frame are out of alignment and the door sits proud of the frame - is there a hinge that handles that offset?
The Design Hardware FSOHD is a full surface offset heavy duty continuous geared hinge, built for an offset condition rather than a flush one. The ABH A210HD is a full surface swing clear hinge with no door inset, so it expects a flush surface application. Check the actual offset at the hinge edge and pick the geometry that matches it, because a geared continuous hinge will not take up misalignment the way a butt hinge shim will.
22) Do the aluminum continuous geared hinge alternatives match the ABH A210HD on fire rating?
The A210HD is approved for metal swinging fire doors up to 90 minutes and wood swinging fire doors up to 60 minutes. Among comparable geared hinges, the NGP HD1100A, NGP HD5400A and NGP HD5700 are each 10C fire rated 90 minute on hollow metal, and the BEST 663HD and BEST 664HD each carry a 90-minute UL fire rating. Those peer ratings are stated for hollow metal, so on a wood fire door the A210HD's 60 minute wood approval is the figure to work from.
23) Is the ABH A210HD suitable for an apartment or house door, or is it commercial only?
This one is built for commercial duty. It is rated commercial, carries BHMA Grade 1 certification, and is aimed at office buildings, schools, healthcare, retail, warehouses, multi-tenant residential and government facilities. On a multi-family building it is used on the corridor, stair and entry doors that take constant traffic, not typically on unit interior doors.
