ABH A500078-US32D – Frequently Asked Questions

1) Do I have to mortise the door and frame to install an ABH A500 hinge?
No mortising of either the door or the frame. The A500 is surface applied and screws on with 12-24 x 3/4 inch undercut self drilling, thread forming tek machine screws that come with it. One useful side effect on retrofit work: the hinge leaf covers the old butt hinge cut-outs, so you are not filling and dressing three mortises before you hang the door.
2) Is the ABH A500 continuous hinge fire rated, and for how long?
Ratings run by door type. Twenty minutes on wood doors, 90 minutes on hollow metal and composite core wood doors, and up to 3 hours on hollow metal. It is also BHMA A156.25 Grade 1 certified. Match the rating to the door leaf you actually have, not to the opening label, since the wood door number and the hollow metal number are three hours apart.
3) The frame will not take a mortised hinge leaf - what continuous hinge works instead of the ABH A500?
The ABH A500 is a full mortise pin and barrel hinge, so it needs both door and frame edges to accept the leaves. Where that is not possible, a full surface hinge mounts on the face of the door and frame instead: the Design Hardware FSHD is a full surface heavy duty continuous geared hinge, the BEST 664HD is a full surface continuous geared hinge with a 90 minute UL fire rating, and the NGP HD5700 is an 83 inch full surface geared hinge with 1/16 inch door inset for 1-3/4 to 2-1/4 inch doors. For an opening where the door face sits proud of the frame, the Design Hardware FSOHD is the full surface offset version of the same heavy duty geared family.
4) My doors are 3/32 inch inset, not 1/8 inch - can I still use the ABH A500?
The ABH A500 is built for a 1/8 inch door inset and every length offered, from 78-3/4 inch through 118-3/4 inch, carries that inset. For a 3/32 inch inset opening the BEST 663HD is a heavy duty continuous hinge specifically for 3/32 inch inset doors with a 90 minute UL fire rating. For a 1/16 inch inset, the NGP HD5700 covers 1-3/4 to 2-1/4 inch doors. Inset is what sets the door to frame clearance, so matching it is what decides whether the door closes correctly.
5) What is a direct alternative to the ABH A500 continuous hinge for a full mortise opening on a heavy commercial door?
The Pemko CFM84SLF-HD1 is an 84 inch full mortise continuous hinge, short leaf flush, heavy duty and Grade 1, and it addresses the same full mortise heavy duty position as the ABH A500 pin and barrel continuous hinge. The difference is in the pivot mechanism and length offering: the A500 uses pin and barrel construction and comes in 78-3/4, 83-1/8, 85, 95 and 118-3/4 inch lengths, while the Pemko is a geared short leaf flush design at a single 84 inch length. On a door taller than a standard opening, the A500's 95 and 118-3/4 inch lengths cover heights the 84 inch Pemko does not reach.
6) For an institutional door that needs a Grade 1 continuous hinge, which options actually carry Grade 1?
The ABH A500 is BHMA 156.25 Grade 1 certified in stainless steel pin and barrel construction. Among the geared alternatives, the Pemko CFM84SLF-HD1 full mortise short leaf flush hinge is Grade 1, the Pemko FM-RG Series aluminum full mortise raised geared hinge is Grade 1 with a 180 degree swing, 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 is Grade 1 with 100 degree bidirectional operation. The NGP HD1100A concealed continuous geared hinge is Grade 3. Where a facility standard names Grade 1 on the drawing, that narrows the set before any other consideration.
7) Can the NGP HD1100A concealed geared hinge be swapped in for the ABH A500 on a fire rated hollow metal opening?
They are not equivalent on the two specs that matter to a fire door submittal. The NGP HD1100A is an 83 inch heavy duty concealed continuous geared hinge, 10C fire rated 90 minute on hollow metal, and Grade 3. The ABH A500 is BHMA 156.25 Grade 1 and carries fire ratings up to 3 hours on hollow metal, with 90 minutes on hollow metal and composite core wood and 20 minutes on wood doors. If the opening is a 3 hour hollow metal door or the specification demands Grade 1, the HD1100A does not satisfy it.
8) Which continuous hinge is stainless steel rather than aluminum for a corrosive or wash-down environment?
The ABH A500 is stainless steel pin and barrel construction with a 689 satin stainless steel finish, which is the reason it gets specified where corrosion resistance matters. The BEST 651 is also a stainless steel full mortise continuous hinge, though at a medium duty level. By contrast the Pemko FM-RG Series is aluminum and the NGP HD5400A is aluminum alloy. For a kitchen, pool, coastal, or wash-down opening, the material is the deciding spec.
9) Can I use the ABH A500 continuous hinge on a federally funded project?
The A500 is BAA qualified, so it clears Buy American Act sourcing requirements on government and municipal work. Combined with BHMA A156.25 Grade 1 certification and stainless steel construction, it is the sort of line item that goes through a public agency submittal without a substitution request coming back at you.
10) Do continuous hinges need handing, and will one ABH A500 do both my left and right hand doors?
Continuous hinges like the A500 are not handed the way a lockset is. The full height leaf and pin and barrel knuckle work on either hand of a full mortise opening, so a property manager standardizing a building buys by length and inset rather than by hand. What you do have to get right is the 1/8 inch inset, the door height, and staying inside 600 lbs and 48 inches of door width.
11) Is the ABH A500 heavy duty enough for a high traffic entrance, or is a standard duty hinge fine?
For a high traffic commercial entry, the A500 is the heavy duty answer: Grade 1, stainless, 600 lb capacity, and rated up to 3 hours on hollow metal. Medium duty continuous hinges such as the BEST 641 steel full mortise and the BEST 651 stainless full mortise, both with hospital tips, are the lighter class and suit interior openings that do not see constant cycling. On a main entrance, a stairwell, or a loading corridor, go heavy duty.
12) Will a continuous hinge stop my commercial doors from sagging?
That is the main reason people move off butt hinges. The A500 carries the door load along the entire height of the opening instead of concentrating it at three or four points, which is what keeps the door in alignment and stops the drag and hinge-side rub that comes from a sagging top butt. On a 600 lb door in a busy building that difference shows up in fewer closer adjustments and fewer door drop callbacks.
13) Which continuous hinge should I use on a 1-3/8 inch door instead of the ABH A500?
The ABH A500 is a heavy duty commercial hinge sized for doors up to 48 inch width and 600 lbs, which is a thicker and heavier door than a 1-3/8 inch leaf. The Pemko FM-SLF is a short leaf flush continuous geared hinge built specifically for 1-3/8 inch doors with Grade 1 construction, and it is the correct choice on that door thickness.
14) What is the difference between the ABH A500 pin and barrel hinge and a geared continuous hinge like the Design Hardware FMHD?
Both are full mortise heavy duty continuous hinges. The ABH A500 uses stainless steel pin and barrel construction with a 1/8 inch door inset, is BHMA 156.25 Grade 1 certified, supports doors to 600 lbs and 48 inch width, and is fire rated up to 3 hours on hollow metal doors. The Design Hardware FMHD is a heavy duty continuous geared hinge, where a continuous gear train rather than a pin and barrel carries the door. Pin and barrel gives a concealed knuckle line; geared designs are the more common aluminum extrusion approach. If the specification calls out a fire rating beyond 90 minutes on hollow metal, the A500's 3 hour rating is the deciding spec.
15) What continuous hinge handles a door that needs to swing both directions or resist being barricaded?
The ABH A500 is a conventional full mortise pin and barrel hinge for standard single direction commercial openings. Where the opening needs bidirectional swing or anti-barricade behavior, such as a behavioral health or detention room, the Pemko DSH1000 is an anti-barricade continuous hinge with 100 degree bidirectional operation and Grade 1 construction. That is a different function entirely, not a substitution for load capacity.
16) Is the NGP HD5400A half surface hinge an alternative to the ABH A500?
Only if the opening is a half surface condition. The NGP HD5400A is an 83 inch half surface continuous geared hinge in aluminum alloy, 10C fire rated 90 minute on hollow metal, which mounts to the door face and into the frame rebate rather than mortising into both edges. The ABH A500 is a full mortise stainless steel pin and barrel hinge with a 1/8 inch door inset. The mounting condition of the existing opening, not the hinge preference, decides between them.
17) I need a 180 degree swing on a full mortise continuous hinge - does the ABH A500 or a Pemko do that?
The Pemko FM-RG Series is a Grade 1 aluminum full mortise raised geared continuous hinge specified with a 180 degree swing, which is the option to reach for when the door has to lay back flat against the wall for equipment or gurney clearance. The ABH A500 is a stainless steel full mortise pin and barrel hinge whose published strengths are the 600 lbs door weight, BHMA 156.25 Grade 1 certification, and fire ratings up to 3 hours on hollow metal.
18) What finish does the ABH A500 continuous hinge come in?
689, satin stainless steel, and that is the only finish in the A500 line here. It reads as a brushed silver alongside 630 satin stainless trim, so it sits comfortably on openings already fitted out in stainless lever and exit hardware. The stainless base material also holds up in wash-down and coastal corridors where a plated steel hinge would start showing rust at the knuckle.
19) Does the ABH A500 come with screws, or do I have to order fasteners separately?
Fasteners are specified with the hinge: 12-24 x 3/4 inch undercut self drilling, thread forming tek machine screws. They are self drilling, so on hollow metal you are not pre-tapping the frame. The hole pattern is templated across the length range, which is what lets a crew hang a run of identical openings without laying out each one.
