Pemko WTCHS83HD1 – Frequently Asked Questions

1) What does wide throw mean on a continuous hinge, and when do I need it?
Wide throw means the hinge pushes the door further off the frame so the leaf clears something in the way, typically a deep frame rabbet, thick wall return, or trim that would otherwise block the swing. The WT-HS is built for retrofits where special frame, door, or wall design demands that extra clearance, and it still gives a full 180 degree maximum swing with a minimum 5/32 inch hinge clearance. If your opening has no obstruction, a standard half surface geared hinge is the simpler choice.
2) How does a half surface continuous hinge mount compared to full mortise?
Half surface means one leaf goes into the frame rabbet and the other is applied to the exposed face of the door, so you only prep the frame side. That is why it suits retrofit work: a full mortise hinge, like the ABH A120HD, needs both the door edge and the frame rabbet machined, which usually means pulling and prepping the door. On the Pemko WT-HS, the surface-applied door leaf is visible on the pull side when the door is closed.
3) Can the Pemko WT-HS be used on a fire rated door?
It is intended for swinging type fire doors, including hollow metal, tin-clad, sheet metal, and steel covered composite doors, and it carries UL 10C fire testing along with ANSI/BHMA A156.26 compliance.
4) I need a swing clear hinge so the door leaf clears the opening for gurney traffic. Is this the right one?
No. Wide throw and swing clear solve different problems. The WT-HS adds throw to get around a frame, wall, or door obstruction on a retrofit; it does not swing the door fully out of the clear opening width. For that, look at a swing clear geared hinge such as the ABH A210HD full surface swing clear, which is the type used in healthcare corridors to recover the door thickness from the clear opening.
5) What is the closest half surface continuous geared hinge to the Pemko WT-HS if I need a standard throw instead of wide throw?
The NGP HD5400A is a half surface continuous geared hinge in aluminum alloy, furnished at 83 inches, and it carries a UL 10C 90 minute fire rating on hollow metal. Like the Pemko WT-HS it mounts to the frame rabbet and the exposed door face, so the door prep approach is the same. The difference is the throw: the WT-HS is the wide throw version, built to clear special frame, door or wall conditions and swing to 180 degrees, while the HD5400A is a conventional half surface geometry. Choose the WT-HS when the opening needs the extra offset to clear trim or a deep frame, and the HD5400A when the jamb condition is standard.
6) If the door face has to stay clear of any applied hardware, what continuous hinge should I use instead of the Pemko WT-HS?
The Pemko WT-HS is a half surface hinge, so one leaf is applied to the exposed door surface. If the door face must stay clean, a full mortise hinge is the alternative: the NGP HD1100A is a concealed continuous geared hinge furnished at 83 inches with a UL 10C 90 minute rating on hollow metal, and the ABH A120HD is a heavy duty aluminum continuous gear hinge in a full mortise configuration. Both conceal within the hinge edge when the door is closed. Note that full mortise requires machining the door and frame edges, which is why the WT-HS half surface design is used on retrofits where that prep is not practical.
7) Is a full surface continuous hinge the same thing as the Pemko WT-HS half surface hinge?
No. The Pemko WT-HS applies one leaf to the frame rabbet and the other to the exposed door surface, which is the half surface arrangement. A full surface hinge applies both leaves to the exposed faces of the door and the frame. Full surface options include the BEST 664HD, a heavy duty full surface continuous geared hinge with a 90 minute UL fire rating, the Design Hardware FSHD heavy duty full surface geared hinge, and the NGP HD5700, a full surface hinge with a 1/16 inch door inset sized for 1-3/4 inch to 2-1/4 inch doors. Full surface suits openings where the frame face is available and the rabbet is not; half surface like the WT-HS suits openings where the frame rabbet is the mounting surface.
8) I need extra clearance at the opening but the door prep is full surface, not half surface. What is the offset equivalent to the Pemko WT-HS?
The Design Hardware FSOHD is a full surface offset heavy duty continuous geared hinge. Offset and wide throw serve the same purpose of pushing the door away from the frame to clear trim, deep reveals or wall returns, but the FSOHD does it in a full surface mounting, while the Pemko WT-HS achieves the extra clearance in a half surface mounting applied to the frame rabbet and exposed door face, with 180 degree maximum swing. Pick based on which frame surfaces you can mount to.
9) Is this hinge heavy duty enough for a high traffic entrance?
The WT-HS is a Grade 1 aluminum continuous geared hinge with 3 inch bearing spacing, which is the top ANSI/BHMA grade tier and the level specified for commercial office, school, healthcare, and industrial traffic. Continuous geared hinges also spread door weight along the full height of the opening rather than concentrating it on three or four butt hinges, which is why they get used where butts keep sagging.
10) What other continuous geared hinges could I use instead of the Pemko WT-HS?
Depends on why you were looking at wide throw. If you do not actually need the extra clearance and just want half surface mounting, the NGP HD5400A is a half surface geared aluminum hinge in an 83 inch length that is 10C fire rated for 90 minutes on hollow metal, and the ABH A460HD is a half surface heavy duty aluminum gear hinge rated to 450 lbs. For full surface mounting on the pull side of both door and frame, look at the BEST 664HD or the Design Hardware FSHD. None of those are wide throw, so if your frame or wall geometry is what forced the wide throw in the first place, stay with the WT-HS.
11) Does the Pemko WT-HS work on a 2-1/4 inch thick door, and which other continuous hinges cover that thickness?
Yes, the Pemko WT-HS accommodates door thicknesses from 1-3/4 inches to 2-1/4 inches and door widths up to 4 feet, in lengths from a 79 inch minimum up to 10 feet, with 83 inch and 95 inch sizes in clear anodized and dark bronze anodized aluminum. Among the peers, the NGP HD5700 is also sized for 1-3/4 inch to 2-1/4 inch doors, though it is a full surface hinge with a 1/16 inch door inset rather than a wide throw half surface unit.
12) Is a steel or stainless continuous hinge available instead of the aluminum Pemko WT-HS?
Yes. The BEST 641 is a steel full mortise continuous hinge with hospital tips at a medium duty level, and the BEST 651 is the stainless steel full mortise version, also medium duty with hospital tips. The Pemko WT-HS is aluminum, Grade 1, in a half surface mounting. The trade is both material and mounting: the BEST 641 and 651 are mortised into the door and frame edges rather than applied to the door face, so they are not a drop-in for a retrofit that relies on surface application.
13) What are the fire rated alternatives to the Pemko WT-HS for a 90 minute labeled opening?
The Pemko WT-HS is UL 10C fire tested and ANSI/BHMA A156.26 compliant for swinging fire doors including hollow metal, tin-clad, sheet metal and steel covered composite. If the mounting condition rules it out, fire rated peers include the BEST 663HD, a heavy duty continuous hinge with a 90 minute UL fire rating for 3/32 inch inset doors, the BEST 664HD full surface heavy duty geared hinge with a 90 minute UL rating, and the NGP HD5700 and HD5400A, both UL 10C 90 minute rated on hollow metal. Confirm the rating applies to your door construction and the label on the assembly.
14) For a school corridor door where hands could reach the hinge edge, is there a safer alternative to the Pemko WT-HS?
The ABH A135HD is a heavy duty aluminum continuous gear hinge built with a safety design, which addresses finger protection at the hinge edge. The Pemko WT-HS is a heavy duty Grade 1 aluminum geared hinge for wide throw half surface retrofits, suited to educational facilities among other commercial settings, but its design intent is clearance rather than pinch protection. If the specification calls for hinge-side finger guarding, the A135HD is the one to look at.
15) Can I use the Design Hardware FMHD in place of the Pemko WT-HS on a retrofit?
Only if the door and frame edges can be machined. The Design Hardware FMHD is a heavy duty full mortise continuous geared hinge, which requires mortising into the hinge edge of the door and the frame. The Pemko WT-HS is a half surface hinge applied to the frame rabbet and the exposed door surface, which is why it is used on retrofit openings where the existing door cannot be prepped, and its wide throw form adds clearance for special frame, door or wall design. On new work with prep available, the FMHD is a valid heavy duty choice; on an existing opening it usually is not.
16) What finishes are available on the Pemko WT-HS wide throw hinge?
Two anodized aluminum finishes: clear anodized and dark bronze anodized. Both are offered in the 83 inch and 95 inch lengths, so you can match existing hinges down a corridor of openings without changing length.
17) Do I have to specify handing when ordering the Pemko WT-HS half surface hinge?
You order by length and finish. What you do need to confirm before install is which face of the door the surface leaf lands on: a half surface hinge mounts to the exposed door face, so it is visible from one side of the opening and needs that face clear of any applied trim, kick plate, or protection plate in the hinge run.
18) Can I use the Pemko WT-HS on a wood or aluminum storefront door?
The fire door applications listed for the WT-HS are hollow metal, tin-clad, sheet metal, and steel covered composite doors. For openings outside those types, verify the door construction can take a surface applied leaf through its full height before specifying it.
19) Does the Pemko WT-HS have any green building documentation for a LEED submittal?
A Health Product Declaration (HPD) is published for the WT-HS series, which is the material transparency document most commonly requested on LEED and institutional submittals alongside the UL 10C and ANSI/BHMA A156.26 data.
