ABH AC500078-US32D – Frequently Asked Questions

1) Will the ABH AC500 ligature resistant hinge work on a behavioral health door that already has butt hinge cutouts?
Yes, and that is one of the reasons it gets specified on retrofits. The AC500 is a surface mount continuous hinge, so no mortising of the door or frame is needed and the leaf covers the old butt hinge cut-outs in both the door and the jamb. You are not patching or replacing the door to get rid of the existing prep.
2) What makes the ABH AC500 ligature resistant, compared to a standard continuous hinge?
Two things. The barrels are cut at 45 degrees and welded so all gaps at the top and bottom are closed, and each barrel is encased in the hinge leaf flange. That gives a "No See Through" hinge with no exposed edge or opening a cord or strap can be looped onto or wedged into. A standard continuous hinge leaves those barrel gaps open at the ends, which is exactly the attachment point this design removes.
3) Does the ABH AC500 hinge need frame reinforcement?
No door reinforcement at all. Frame reinforcement is only required when the door exceeds 200 lbs, and then it is 16 gauge channel. Under that weight you are mounting to the existing frame. That threshold matters on heavy institutional doors, so weigh the leaf before you assume you are clear.
4) Is the ABH AC500 hinge Grade 1 certified?
The AC500 is certified to ANSI BHMA 156.26 Grade 1, which is the continuous hinge standard. That is the grade level most behavioral health and correctional specs call out for door hardware in patient and inmate areas.
5) What screws come on the AC500 hinge and can an inmate or patient back them out?
Pin-in-Torx security fasteners. The pin in the center of the drive means a standard Torx bit will not seat, so a pilfered or improvised driver does not turn them. You need the matching pin-in-Torx bit on hand at install and for any later service, so put one in the maintenance kit.
6) Do I need a ligature resistant hinge, or will a regular heavy duty continuous hinge do?
It depends on the room, not the door. In patient bedrooms, seclusion rooms, bathrooms, and anywhere an at-risk occupant is alone, the hinge needs the welded 45 degree barrel and encased flange the AC500 has, because an ordinary continuous hinge leaves barrel gaps that will hold a cord. In staff corridors, mechanical rooms, and administrative areas a standard heavy duty continuous hinge is normal practice, and ZenSupply carries those from Design Hardware (the FMHD full mortise heavy duty geared hinge) and BEST (the 663HD heavy duty hinge). Those are not ligature resistant and should not go on a patient side door.
7) The AC500 is not fire rated for my 90 minute opening - what continuous hinge should I use instead?
For a 90 minute rated opening, look at the BEST 663HD Heavy Duty Continuous Hinge, which is 90 minute UL fire rated and built for 3/32 inch inset doors, or the BEST 664HD full surface continuous geared hinge with a 90-minute UL fire rating. On the NGP side, the HD1100A concealed geared hinge, the HD5400A half surface, and the HD5700 full surface are all 10C fire rated 90 minute on hollow metal. Choose by mounting: 663HD is for an inset door, 664HD, HD5700 and the FSHD full surface geared hinge from Design Hardware mount to the face of door and frame, and the HD5400A is half surface.
8) What is the closest equivalent to the ABH AC500 ligature resistant continuous hinge for a behavioral health opening where a barricade risk also has to be addressed?
The AC500 addresses ligature attachment with barrels cut at 45 degrees and welded to close the gaps at top and bottom, each barrel encased in the hinge leaf flange for a No See Through condition, and Pin-in-Torx security fasteners. If the concern on the opening is a patient barricading the door rather than ligature attachment, the Pemko DSH1000 Anti-Barricade Continuous Hinge is the part that speaks to it, with 100-degree bidirectional operation so the door can swing the other way. Both are continuous hinges; the DSH1000 is Grade 1. They solve two different behavioral health problems, so on an opening carrying both risks confirm which one governs the spec before ordering.
9) Do the BEST hospital tip continuous hinges do the same thing as the ABH AC500 in a psychiatric unit?
They do not. The BEST 641 steel full mortise standard duty continuous hinge and the BEST 651 stainless steel full mortise continuous hinge both carry hospital tips, which chamfer the hinge ends so nothing catches, and both are medium duty. Hospital tips are not the same as the AC500 ligature treatment: the AC500 cuts the barrel at 45 degrees and welds it to close all gaps top and bottom, with each barrel encased in the leaf flange so there is no see through and no attachment point. If a behavioral health spec calls out ligature resistance, hospital tips alone will not satisfy it.
10) Will a continuous hinge stop my doors from sagging and dragging?
That is the main mechanical reason to go continuous. Instead of loading three or four butt hinge points, the AC500 runs the full height of the leaf and distributes the door weight along the entire door and frame, which is what eliminates the binding and sagging you get when butt hinges start to wear. On a high traffic institutional opening that is usually the difference between adjusting doors every year and leaving them alone.
11) Is the ABH AC500 hinge Buy American Act qualified for a government or VA project?
No. The AC500 is not BAA qualified, so on a federal job with a Buy American requirement it will not clear the submittal. Worth catching before you spec it into a VA or federal corrections package rather than at approval.
12) Does the AC500 hinge close the gap between the door and the frame for security?
Yes. Running the full height with the welded barrel construction eliminates the gap between door and frame along the hinge edge, which takes away the purchase a pry bar needs on that side. On a correctional or seclusion door that removes one of the two obvious attack points, the other being the strike edge, which you handle with the lock and frame reinforcement.
13) Is there an anti-barricade hinge option for a behavioral health room instead of a ligature resistant hinge?
Different problem, different hinge. The AC500 addresses ligature attachment on the hinge edge. If the concern is a patient blocking the door shut so staff cannot get in, that calls for the Pemko DSH1000 anti-barricade continuous hinge, which is Grade 1 and swings bidirectionally through 100 degrees so the door can be pushed the other way. Many behavioral health projects use a ligature resistant hinge on corridors and storage and the anti-barricade type on patient bedrooms and bathrooms.
14) I need a Grade 1 continuous hinge in a length other than the AC500 sizes - what else is Grade 1?
The AC500 is ANSI BHMA 156.26 Grade 1 certified and comes in 78-3/4, 83-1/8, 85, 95 and 118-3/4 inch lengths. Other Grade 1 continuous hinges include the Pemko 84 inch full mortise short leaf flush heavy duty hinge, the Pemko FM-RG Series aluminum full mortise raised geared hinge with 180-degree swing, the Pemko short leaf flush geared hinge for 1-3/8 inch doors, and the Pemko DSH1000 anti-barricade hinge. None of those carry the AC500 ligature resistant barrel treatment, so on a behavioral health opening confirm the spec allows a standard Grade 1 hinge first.
15) What full mortise continuous hinge should I use on a standard commercial door that does not need the ligature resistant features of the AC500?
For an ordinary commercial opening, the Design Hardware FMHD full mortise heavy duty continuous geared hinge and the Pemko 84 inch full mortise short leaf flush heavy duty Grade 1 hinge both cover the same job without the ligature detailing. The Pemko FM-RG Series is a Grade 1 aluminum full mortise raised geared hinge with a 180-degree swing, and the Pemko short leaf flush geared hinge is sized for 1-3/8 inch doors. Where the AC500 differs is in what it adds: welded 45-degree barrels with no see through and Pin-in-Torx security fasteners, which matter in behavioral health and correctional work and are extra detail on a standard office or corridor door.
16) The AC500 mounts to the surface with no mortising - what continuous hinge do I use if my door and frame are already prepped for a mortise or offset hinge?
The AC500 is surface mount, so no mortising of the door or frame is needed and it covers old butt hinge cutouts. If the opening is prepped differently, the Design Hardware FMHD full mortise heavy duty continuous geared hinge suits a mortised door and frame, the FSOHD full surface offset heavy duty geared hinge suits an opening needing an offset pivot condition, and the NGP HD5400A is a half surface hinge. All are continuous geared hinges; the mounting condition of the existing door and frame is what decides between them.
17) My doors are 1/16 inch inset, not the 1/8 inch the AC500 is built for - what are my options?
The AC500 is supplied for a 1/8 inch door inset. For other inset conditions, the NGP HD5700 full surface continuous geared hinge is built around a 1/16 inch door inset and covers 1-3/4 inch to 2-1/4 inch doors, and the BEST 663HD heavy duty continuous hinge is for 3/32 inch inset doors. Measure the existing gap at the hinge edge before ordering, since the inset dimension is what determines whether the hinge closes correctly against the frame.
18) Can I use the ABH AC500 hinge on a residential door?
It is a commercial product, built for institutional service, and nothing about it is scaled for a house. The lengths start at 78-3/4" for a full height leaf, the fasteners are pin-in-Torx security screws that need a special bit, and the ligature resistant barrel design exists for behavioral health and correctional openings. On a residential opening it is more hinge than the door needs and more service hassle than a homeowner wants.
19) Does the ABH AC500 hinge come in finishes other than stainless?
Satin stainless steel is the finish across all five lengths of the AC500. If your facility standard is a different finish on the rest of the door hardware, the hinge will read as stainless against it.
20) Is a medium duty continuous hinge enough, or do I need something in the class of the ABH AC500?
The AC500 is a continuous hinge that distributes door weight evenly across the full height of the door and frame, needs no door reinforcement, and only calls for 16 gauge channel frame reinforcement on doors over 200 lbs. In the same continuous hinge family, the BEST 641 and BEST 651 are medium duty, while the BEST 663HD, BEST 664HD, and the Design Hardware FMHD, FSHD and FSOHD are heavy duty. Match the duty level to the door weight and traffic on the opening; a heavy institutional door in constant use is the case the heavy duty parts are built for.
