ABH A410 HD C 079 – Frequently Asked Questions

1) Will the ABH A410HD continuous hinge work on a 1-3/4 inch door that's 48 inches wide?
That's exactly the opening the A410HD is built for. It's rated for 1-3/4 inch thick squared edge doors up to 48 inches wide and 450 lbs. Go wider than 48 inches or heavier than 450 lbs and you're outside what the A410HD covers. The door edge has to be squared, not beveled, since the hinge mounts flush with no door inset.
2) What's the difference between the ABH A410HD and the A410LL?
Weight capacity and hole pattern. The A410HD carries doors up to 450 lbs. The A410LL uses a lead-lined staggered hole pattern and handles doors up to 1,000 lbs, which is what you want on a lead-lined X-ray or imaging room door where the lead core adds serious weight and the fasteners have to miss the lead. Ordering is a single option on the hinge: For Lead-Lined Doors, Yes or No.
3) Is the ABH A410 continuous hinge fire rated, and for how long?
Yes. The A410HD/A410LL is approved for metal swinging fire doors up to 90 minutes and wood swinging fire doors up to 60 minutes. If you're carrying a 90 minute label on a wood door, this hinge won't hold that assembly, and you need a different hinge.
4) Do I have to mortise the door and frame to install an ABH A410 hinge?
No mortising of the door or frame is required. It's a flush mount with no door inset, and the leaves cover over the old butt hinge cut-outs, which is what makes it a practical retrofit on a door that's already sagging on three butts. Fasteners are in the box: 12-24 x 3/4 inch undercut self drilling, thread forming tek machine screws, so the mounting holes get drilled and formed as you drive them on hollow metal.
5) Is the ABH A410 Grade 1, and does it qualify for a Buy American federal job?
Both. The A410HD/A410LL meets BHMA 156.25 Grade 1, the top durability tier for continuous hinges, and it's BAA qualified, so it clears Buy American Act requirements on federal and municipal work. It's a commercial-rated product, not a residential one.
6) My door has a 3/32 inch inset - will the ABH A410HD work, or do I need a different hinge?
The A410HD is built for squared edge doors with no door inset, and every configuration of it is ordered with door inset None. For an inset opening, BEST's 663HD is a heavy duty continuous geared hinge made for 3/32 inch inset doors and carries a 90 minute UL fire rating, and NGP's HD5700 covers a 1/16 inch inset on 1-3/4 inch to 2-1/4 inch doors. Measure the gap at the hinge edge before choosing.
7) My opening is a 1-3/8 inch door - does the ABH A410HD fit, or is there another hinge?
The A410HD is engineered for 1-3/4 inch thick squared edge doors. For a 1-3/8 inch leaf, Pemko's FM-SLF is a short leaf flush continuous geared hinge built for 1-3/8 inch doors with Grade 1 construction, and it mortises the same way. Pemko's CFM84SLF-HD1 is the 84 inch heavy duty Grade 1 short leaf flush full mortise hinge in the same family.
8) What is the closest equivalent to the ABH A410HD full mortise continuous geared hinge from another manufacturer?
The Design Hardware FMHD is the direct counterpart: a full mortise heavy duty continuous geared hinge, the same mounting family and duty level as the ABH A410HD. Pemko's FM-RG Series is another Grade 1 aluminum full mortise geared continuous hinge, with a 180 degree swing, and the Pemko CFM84SLF-HD1 is a Grade 1 heavy duty full mortise short leaf flush hinge in an 84 inch length. All three mortise into the door edge and frame rabbet the way the A410HD does, so the prep carries over; confirm length and finish against the opening before you order.
9) Which continuous geared hinges besides the ABH A410HD are Grade 1?
The ABH A410HD carries BHMA 156.25 Grade 1 certification. Among comparable continuous geared hinges, Pemko's FM-RG Series, the Pemko CFM84SLF-HD1 full mortise short leaf flush hinge, the Pemko FM-SLF, and the Pemko DSH1000 anti-barricade hinge are all Grade 1. NGP's HD1100A concealed geared hinge is Grade 3. If your specification calls out Grade 1 across a facility, that narrows the substitution set considerably.
10) What continuous hinge should I specify for a behavioral health or detention opening instead of a standard swing clear hinge?
The ABH A410HD is a swing clear hinge, which clears the door leaf out of the opening for wheelchair and gurney traffic - a healthcare corridor answer, not an anti-ligature or anti-barricade one. Where the concern is a door being blocked from the inside, Pemko's DSH1000 is a Grade 1 anti-barricade continuous hinge with 100 degree bidirectional operation, letting the door swing either way. Those solve different problems; choose by which risk governs the room.
11) I need a continuous hinge for a lead-lined x-ray room door - what are my options?
The ABH A410LL is the lead-lined configuration of the A410 series, ordered by selecting For Lead-Lined Doors Yes, with a staggered hole pattern and capacity to 1,000 lbs to carry the added leaf weight. The comparable full mortise heavy duty geared hinges - Design Hardware FMHD, Pemko FM-RG Series, Pemko CFM84SLF-HD1 - are the mounting equivalents of the standard A410HD rather than lead-lined variants, so for a shielded door the A410LL is the configuration to order.
12) I need a 90 minute fire rated continuous hinge - which models qualify?
The ABH A410HD is approved for metal swinging fire doors up to 90 minutes and wood swinging fire doors up to 60 minutes. Among the comparable geared hinges, BEST's 663HD and 664HD both carry a 90 minute UL fire rating, and NGP's HD1100A, HD5400A, and HD5700 are each 10C fire rated for 90 minutes on hollow metal. Match the rating to the door construction on your opening, since several of those ratings are stated for hollow metal specifically.
13) Are the ABH A410HD and the Pemko FM-RG Series interchangeable?
Both are Grade 1 aluminum full mortise continuous geared hinges, so they occupy the same slot on a hardware schedule. The difference is the gear detail and swing: the Pemko FM-RG is a raised geared hinge with a 180 degree swing, while the ABH A410HD is a full concealed swing clear hinge that clears the leaf out of the opening width. On a corridor where clear opening width drives the ADA calculation, that is not a swap - the swing clear geometry is the reason the A410HD is specified.
14) Will a continuous geared hinge stop my heavy commercial door from sagging?
That's the reason to move off butt hinges. The A410HD runs the full height of the door and distributes the load along the entire door and frame instead of concentrating it on three or four points, which is what eliminates the binding and sag you get when butt hinges wear out on a high-traffic opening. It carries up to 450 lbs on a 1-3/4 inch door. It also closes the gap between door and frame, so there's no purchase for a pry bar along the hinge edge.
15) Should I use a full mortise continuous hinge or a full surface one?
It comes down to what your frame and door will accept. The ABH A410HD is full mortise: it sits between the door edge and the frame rabbet with no inset, so the door edge must be squared and the door has to be pulled to fit it. A full surface hinge mounts on the face of the door and frame instead, which is the option when the door edge is beveled, the frame is beat up, or you don't want to pull the door. ZenSupply carries full surface heavy duty geared hinges from Design Hardware in the FSHD series, plus the FSOHD offset version for doors that need to clear a wrap. The BEST 664HD is another full surface heavy duty geared hinge with a 90-minute UL fire rating.
16) Do I need to specify handing when I order an ABH A410 continuous hinge?
No handing to call out. The A410HD/A410LL is ordered by length, finish, and whether it's the lead-lined pattern. That's it. Continuous geared hinges are symmetrical and mount to either jamb, so one part number covers left and right hand openings, which is why they're easy to stock across a fleet of doors.
17) Is the NGP HD1100A a substitute for the ABH A410HD?
They are not interchangeable on a Grade 1 specification. The NGP HD1100A is an 83 inch concealed continuous geared hinge listed at Grade 3 and 10C fire rated for 90 minutes on hollow metal; the ABH A410HD is BHMA 156.25 Grade 1 and approved for metal swinging fire doors up to 90 minutes and wood swinging fire doors up to 60 minutes. If the drawing calls Grade 1, stay with the A410HD or a Grade 1 peer such as the Pemko FM-RG Series.
18) What is the difference between a full surface offset geared hinge and the ABH A410HD full mortise?
The A410HD mortises into the door edge and frame on a squared edge 1-3/4 inch door with no inset, so the barrel sits concealed in the opening. Design Hardware's FSOHD is a full surface offset heavy duty continuous geared hinge - it mounts to the face of the door and frame and offsets the pivot line outward, which is how you get a door to swing past a projecting frame or wall condition the mortised A410HD cannot clear. Design Hardware also lists the FSHD as the non-offset full surface version.
19) Which continuous hinges come with hospital tips?
The BEST 641 steel full mortise standard duty continuous hinge and the BEST 651 stainless steel full mortise continuous hinge are both listed with hospital tips, the angled end cap that keeps IV lines, gown ties, and cart straps from catching on a square hinge end. Both are medium duty. The ABH A410HD is a heavy duty aluminum swing clear hinge rated to 450 lbs, so on a healthcare corridor the trade is between the tip detail and the load rating.
20) Does a federal job that requires domestic material limit which continuous hinge I can use?
The ABH A410HD is BAA qualified and specified as commercial grade, which is what a government or municipal project asking for Buy American compliance needs to see on the submittal. Cross-brand substitutions from the comparable geared hinge set - Design Hardware FMHD, Pemko FM-RG Series, BEST 663HD - are matched on mounting type and duty level, so if a domestic material clause governs, confirm that separately for whichever peer you schedule.
21) What finishes does the ABH A410 continuous hinge come in for matching existing doors in a building?
Three anodized aluminum finishes: clear anodized aluminum, dark bronze, and black. All three are available in every length from 79 to 120 inches and in both the standard and lead-lined hole patterns, so you can standardize one finish across a whole facility regardless of door height or whether some openings are lead-lined.
