ABH ABH-A150HD/A150LL-CL-79-NO-NO – Frequently Asked Questions

1) Will the ABH A150HD continuous geared hinge work on a 1-3/4 inch aluminum entrance door?
That is exactly the opening the A150HD is built for. It is a full mortise continuous geared hinge for 1-3/4 inch thick doors up to 48 inches wide, and it was engineered specifically for Kawneer Tuffline aluminum doors. If your door is thicker than 1-3/4 inches or wider than 48 inches, this is the wrong hinge for that leaf.
2) What is the difference between the ABH A150HD and the A150LL, and which one do I order?
Load capacity is the split. The A150HD carries a door up to 450 lbs. The A150LL uses a staggered hole pattern and carries up to 1,000 lbs, which is what a lead-lined X-ray room door needs. On the order you pick it with the lead-lined door option, yes or no. Both come in the same lengths and finishes, so a hospital standardizing on one look can run HD on the corridor doors and LL on the imaging suite doors and have them match.
3) Is the ABH A150 continuous geared hinge fire rated?
Approved for metal swinging fire doors up to 90 minutes and wood swinging fire doors up to 60 minutes. It also carries BHMA A156.25 Grade 1 certification. Note the wood door limit is 60, not 90, so on a 90 minute wood opening this hinge does not carry the rating you need.
4) Do I have to mortise the door and frame to install an ABH A150 hinge?
No mortising of the door or frame is required. The hinge is surface applied and it covers over old butt hinge cut-outs, which is why it is a common fix for a door that has sagged and chewed out its hinge pockets. Fasteners are included: 12-24 x 3/4 inch undercut self drilling, thread forming tek machine screws.
5) Can a continuous geared hinge fix a door that keeps sagging and dragging on the frame?
That is the main reason property managers move to one. A continuous hinge runs the full height of the door and spreads the weight along the entire edge instead of concentrating it on three butt points, so the alignment problems that come from a single overloaded hinge go away. The A150 hinge in 83 inch length runs 32 bearings at 3 inch spacing on center. On a high traffic opening that has already destroyed its butt hinge prep, it is a retrofit because it covers the old cut-outs.
6) Full mortise or full surface continuous hinge, which should I use?
Full mortise, like the ABH A150HD, sits between the door and frame with the leaves concealed when the door is closed, so there is no gap to pry and nothing showing on the face. That requires the door and frame edges to accept it. Full surface mounts on the face of the door and frame and is what you use when the frame will not take a mortised leaf, on a wrapped or damaged frame, or on a door that already swings out. For that route, ZenSupply carries the Design Hardware Full Surface Heavy Duty geared hinge and the BEST 664HD full surface geared hinge, both heavy duty.
7) What else could I use instead of the ABH A150 if my door is not 1-3/4 inches thick?
The A150 is a single thickness hinge, 1-3/4 inch only. For a 1-3/8 inch door, the Pemko Short Leaf Flush continuous geared hinge is a Grade 1 full mortise option built for that thickness. For thicker leaves up to 2-1/4 inches, the NGP HD5700 is an 83 inch full surface geared hinge with a 1/16 inch door inset that covers 1-3/4 to 2-1/4 inch doors, though it mounts on the face rather than mortised.
8) Which continuous hinge do I use on a lead-lined X-ray door?
The A150LL is the version for that. Lead-lined doors are far heavier than a normal leaf, and the LL carries up to 1,000 lbs against 450 lbs for the standard A150HD, using a staggered hole pattern to spread the load. Order it in the length that matches your door height, in 79, 83, 85, 95 or 120 inches.
9) What is the closest full mortise Grade 1 continuous geared hinge to the ABH A150HD in another brand?
The Pemko FM-RG Series is the nearest match: it is a Grade 1 aluminum full mortise raised geared continuous hinge with a 180-degree swing, so like the A150HD it mounts into the door and frame edge rather than on the face. The A150HD is a full mortise hinge rated BHMA 156.25 Grade 1 for 1-3/4 inch doors up to 48 inches wide and 450 lbs, and the lead-lined A150LL version carries up to 1,000 lbs. If your prep is short leaf flush rather than raised gear, the Pemko 84 inch full mortise short leaf flush heavy duty hinge is also Grade 1 and full mortise, and the Design Hardware FMHD is a heavy duty full mortise continuous geared hinge as well.
10) The door and frame will not take a mortise prep - what continuous geared hinge should I use instead of the ABH A150HD?
Use a full surface continuous geared hinge, which mounts to the face of the door and frame with no edge prep. The Design Hardware FSHD is a heavy duty full surface continuous geared hinge, and the BEST 664HD is a heavy duty full surface continuous geared hinge with a 90-minute UL fire rating. The NGP HD5700 is an 83 inch full surface geared hinge built with a 1/16 inch door inset for 1-3/4 inch to 2-1/4 inch doors and is 10C fire rated 90 minutes on hollow metal. The ABH A150HD is a full mortise hinge for 1-3/4 inch thick doors and requires that mortise condition.
11) Is the NGP HD1100A concealed geared hinge the same thing as the ABH A150HD?
They are both 83 inch heavy-duty concealed-type continuous geared hinges, but they are not graded the same. The NGP HD1100A is listed as Grade 3 and 10C fire rated 90 minutes on hollow metal. The ABH A150HD is BHMA 156.25 Grade 1 certified and is approved for metal swinging fire doors up to 90 minutes and wood swinging fire doors up to 60 minutes. If a submittal calls out Grade 1 on a continuous hinge, the A150HD meets that line and the HD1100A is written to a different grade.
12) My existing door has an inset gap at the hinge edge - can I use the ABH A150HD or do I need a different hinge?
Hinges built for an inset condition are a separate family. The BEST 663HD is a heavy duty continuous hinge, 90 minute UL fire rated, made for 3/32 inch inset doors, and the NGP HD5700 is built with a 1/16 inch door inset for 1-3/4 inch to 2-1/4 inch doors. The ABH A150HD is offered with a door inset of None, so it is the choice when the door sits flush at the hinge edge rather than inset.
13) I have 1-3/8 inch doors - will the ABH A150HD work, and what is the alternative?
The ABH A150HD is engineered for 1-3/4 inch thick doors. For a 1-3/8 inch door, the Pemko short leaf flush continuous geared hinge is built for 1-3/8 inch doors with Grade 1 construction. Both are continuous geared full mortise style hinges, so the mounting concept carries over; the door thickness is what separates them.
14) Does the ABH A150 continuous hinge meet Buy American requirements for a federal job?
It is BAA qualified, which is what a government or municipal spec typically asks for. It is a commercial rated product, BHMA A156.25 Grade 1, and it is used on government and municipal buildings along with healthcare, education and industrial facilities.
15) Do continuous geared hinges come in handed versions, or do I order one for either hand?
Handing is not an ordering option on the ABH A150 hinges. What you specify is length, finish, and whether the door is lead-lined. There is no keying or lock function involved either, so a locksmith ordering these needs only the door height, the door weight class, and the finish to match the rest of the opening.
16) Is a heavy duty continuous hinge worth it over a standard duty one on a high traffic entrance?
On an entrance that cycles all day, a standard or medium duty hinge is the wrong tool. The A150HD is heavy duty at 450 lbs door weight with BHMA A156.25 Grade 1 certification. Medium duty steel options like the BEST 641 and the stainless BEST 651, both full mortise with hospital tips, are aimed at lighter interior openings. On a main entrance or a warehouse door, stay with a heavy duty geared hinge.
17) What is a lighter duty continuous hinge for an interior door that does not need the ABH A150HD capacity?
The BEST 641 is a steel full mortise standard duty continuous hinge with hospital tips, listed at medium duty, and the BEST 651 is the stainless steel full mortise version with hospital tips, also medium duty. Both are full mortise like the ABH A150HD, so the prep concept is the same. The A150HD is the heavier specification: aluminum, BHMA Grade 1, 450 lbs door weight, with the A150LL rated to 1,000 lbs for lead-lined doors.
18) Can I use the ABH A150HD as an anti-barricade hinge on a behavioral health or detention door?
No - that is a different product type. The Pemko DSH1000 is an anti-barricade continuous hinge with 100-degree bidirectional operation, which is what lets a door swing both ways so an occupant cannot block it. The ABH A150HD is a full concealed full mortise geared hinge with BHMA Grade 1 certification, designed to eliminate gaps between door and frame for security and to distribute door weight evenly; it does not provide bidirectional swing.
19) Which continuous hinge should I standardize on across a facility if some openings are mortise prepped and others are not?
Standardize on one geared platform and pick the mount per opening. For mortise-prepped openings the ABH A150HD is a BHMA 156.25 Grade 1 full mortise hinge for 1-3/4 inch doors up to 48 inches wide, BAA qualified, approved for metal swinging fire doors up to 90 minutes and wood swinging fire doors up to 60 minutes. For openings that cannot be prepped, the Design Hardware FSHD full surface and FSOHD full surface offset are both heavy duty continuous geared hinges, and the Design Hardware FMHD covers the heavy duty full mortise condition. All are heavy duty, so the duty level stays consistent across the fleet.
20) What finishes do the ABH A150 continuous gear hinges come in, and will they match my storefront doors?
Three finishes: clear anodized aluminum, dark bronze, and black. Clear anodized and dark bronze are the two standard aluminum storefront finishes, so the hinge can be matched to existing Kawneer style entrances without an odd bright edge showing at the jamb. Every finish is offered in all five lengths and in both the standard and lead-lined versions.
