Pemko WTCFM83HD1 – Frequently Asked Questions

1) What does a wide throw continuous hinge do that a standard continuous hinge doesn't?
A wide throw hinge sets the pivot point farther off the frame so the door clears obstructions the standard geometry would hit. On the Pemko WT-FM, that shows up as extra clearance between door and frame, a minimum 5/16 inch clearance spec, and a full 180 degree swing so the leaf lays flat back against the wall. It is the part to specify when applied trim, a deep reveal, or wall-mounted equipment is fouling the door, or where you need the opening fully clear for gurneys and carts. If nothing is in the way, a standard full mortise geared hinge does the same job in less depth.
2) Will the Pemko WT-FM continuous hinge work on a 1-3/4 inch hollow metal door?
Yes, 1-3/4 inches is the top of the range for the WT-FM, and it is the standard commercial door thickness. It is a full mortise hinge, so both the door edge and the frame rabbet get prepped for it. It goes into standard hollow metal doors and frames with self-drilling Teks fasteners and no special hinge reinforcements. Doors up to 4 feet wide are covered.
3) Do I have to order the Pemko WT-FM hinge handed, left or right?
No. The WT-FM is non-handed, so one part number covers a left hand or right hand opening and you can stock a single length for a run of doors that swing both ways. That matters on a fleet order for a building where the handing varies opening to opening.
4) What is the closest full mortise continuous geared hinge to the Pemko WT-FM?
The Pemko WT-FM is a full mortise continuous geared hinge in aluminum. The closest peers by mounting and gear type are the ABH A120HD, a heavy duty aluminum continuous gear hinge in full mortise with easy install technology, and the Design Hardware FMHD, a heavy duty full mortise continuous geared hinge. The difference to check before ordering is the wide throw geometry: the WT-FM is built to carry the door out away from the frame for extra clearance, while the A120HD and FMHD are standard full mortise geometry. If the opening needs the door to clear a projecting trim or reveal, that throw is the reason to stay with the WT-FM.
5) The frame is already drilled and I do not want to mortise it. What continuous hinge goes on instead of a full mortise?
A full mortise hinge such as the Pemko WT-FM sets into the door edge and frame rabbet, so it needs that prep. When the existing frame cannot be cut, a surface mounted continuous geared hinge applies to the face instead. The ABH A460HD is a half surface aluminum continuous gear hinge rated at 450 lbs capacity, the Design Hardware FSHD is a heavy duty full surface geared hinge, and the NGP HD5400A is an 83 inch half surface geared hinge in aluminum alloy. All three change where the leaves land, so confirm the door face has clear room for the leaf before ordering.
6) I need the door to swing clear of the opening for a gurney or wheelchair. Is the Pemko WT-FM the right hinge?
The Pemko WT-FM is a wide throw full mortise hinge with 180 degree swing, which carries the door clear of projecting frame trim, but the door still parks in the opening. For a true swing clear that pulls the door leaf out of the clear width, the ABH A210HD is a full surface swing clear continuous gear hinge in aluminum rated at 450 lbs capacity. On healthcare corridors where the measured clear opening is the code driver, that is the different hinge geometry to specify.
7) Which continuous hinges besides the Pemko WT-FM carry a 90 minute fire rating for a hollow metal opening?
The Pemko WT-FM is UL 10C certified for positive pressure fire tests and meets ANSI/BHMA A156.26. Among comparable continuous geared hinges, the NGP HD1100A concealed hinge, the NGP HD5400A half surface, and the NGP HD5700 full surface are each 10C fire rated 90 minute on hollow metal, and the BEST 663HD and BEST 664HD are 90 minute UL fire rated heavy duty continuous hinges. For an institutional buyer standardizing rated openings, all of these clear the rating; the choice comes down to mounting style and to whether the opening needs the WT-FM wide throw clearance.
8) My door has an inset at the frame. Which continuous hinge matches that instead of the Pemko WT-FM?
Inset dimension decides the hinge on a surface applied opening. The BEST 663HD is a heavy duty continuous hinge for 3/32 inch inset doors, and the NGP HD5700 is a full surface geared hinge with 1/16 inch door inset for 1-3/4 inch to 2-1/4 inch doors. The Pemko WT-FM is a full mortise hinge that accommodates doors up to 1-3/4 inch thick with a 5/16 inch minimum clearance, so it is specified off the mortise prep and clearance rather than an inset figure. Measure the existing gap before you choose between them.
9) I need a continuous hinge longer than 83 inches. Which options run long?
The Pemko WT-FM comes in 83 inch, 95 inch, and 120 inch lengths, with the series running from 79 inch minimum to a 10 foot maximum and custom lengths available. Several comparable geared hinges are catalogued at a single 83 inch length, including the NGP HD1100A, the NGP HD5400A, and the NGP HD5700. If the opening is a tall storefront or an oversized frame past standard door height, the WT-FM length range is the reason to stay with it.
10) Full mortise or full surface continuous hinge, which one do I need?
Full mortise, which is what the Pemko WT-FM is, means the hinge sits into a prepped door edge and frame rabbet so it is concealed when the door is closed. Pick it on new doors and frames, or on a retrofit where the existing prep is clean and square. Full surface hinges screw onto the face of the door and frame with no prep at all, which is the repair route when the frame edge is chewed up or the door is already installed. ZenSupply carries full surface geared hinges from Design Hardware (FSHD) and NGP (HD5700), and ABH offers a full surface swing clear version, the A210HD, if the goal is maximum clear opening width.
11) What else could I use instead of the Pemko WT-FM if I don't need the wide throw?
If nothing is obstructing the door swing, a standard full mortise geared hinge is the simpler buy. ABH's A120HD is an aluminum full mortise continuous gear hinge, and Design Hardware's FMHD is a heavy duty full mortise geared hinge. On the steel side, BEST's 641 is a steel full mortise continuous hinge and the 651 is the stainless version, both with hospital tips, which is what healthcare and behavioral health specs usually call for. None of those give you the extra door-to-frame clearance the wide throw geometry provides, so keep the WT-FM if the door has to clear applied trim or swing a full 180 degrees.
12) What is a lighter duty continuous hinge than the Pemko WT-FM for a low traffic door?
The Pemko WT-FM is a Grade 1 aluminum continuous geared hinge built for heavy commercial traffic. On a low traffic interior opening such as a closet, storage room, or a tenant unit door, 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 at the same medium duty level. Both are pin and barrel style hinges with hospital tips rather than geared aluminum, so the look at the door edge is different from the WT-FM.
13) Can I use the NGP HD1100A in place of the Pemko WT-FM?
They are not the same install. The NGP HD1100A is a concealed continuous geared hinge in an 83 inch heavy duty length, meaning the gear runs hidden in the gap when the door is closed. The Pemko WT-FM is a full mortise wide throw hinge whose wide throw is the whole point, holding the door out from the frame for extra clearance. A concealed hinge will not give you that offset. The HD1100A is the right call when the specification asks for a hinge that does not show at the edge of a closed door, not when the opening needs throw.
14) What continuous hinge do I use on a door that is offset from the frame face?
For an offset condition on a surface applied opening, the Design Hardware FSOHD is a full surface offset heavy duty continuous geared hinge, built for exactly that geometry. The Pemko WT-FM handles a related problem from the other direction, using wide throw full mortise geometry with 180 degree swing to carry the door clear of the frame. Which one fits depends on whether the frame will take a mortise or the hinge has to land on the faces.
15) Do I need an aluminum geared hinge or a steel continuous hinge on a healthcare door?
The Pemko WT-FM is aluminum geared construction with 3 inch bearing spacing, and the ABH A120HD and ABH A135HD are likewise heavy duty aluminum continuous gear hinges, the A135HD carrying a safety design. On the steel side, the BEST 641 is a steel full mortise continuous hinge with hospital tips and the BEST 651 is the stainless steel version, both at medium duty. Hospital tips are the sloped end detail that gives nothing to catch on. Facilities that specify stainless at the door edge for cleaning protocol usually land on the 651; those specifying geared aluminum for traffic land on the WT-FM or the ABH units.
16) I need a finger safety hinge on a school door. Is the Pemko WT-FM that hinge?
No. The Pemko WT-FM is a wide throw full mortise geared hinge whose design intent is clearance between door and frame with 180 degree swing. For a pinch point concern on an educational opening, the ABH A135HD is a heavy duty aluminum continuous gear hinge with safety design and is the unit to look at for that requirement. If the same door also needs the door to lie flat against the wall, confirm the swing the A135HD supports before you substitute.
17) The BEST 664HD is full surface. Will it replace a Pemko WT-FM on the same door?
Not without changing the door prep. The BEST 664HD is a full surface continuous geared hinge with a 90 minute UL fire rating, so it mounts on the faces of the door and frame. The Pemko WT-FM is full mortise, cut into the door edge and frame. A door already mortised for the WT-FM will show that prep if you switch to a face mounted hinge, and the WT-FM wide throw clearance goes away. Treat the 664HD as the answer for a frame that cannot be mortised, not as a drop in for an existing WT-FM opening.
18) What finishes does the Pemko WT-FM wide throw hinge come in?
Two anodized aluminum finishes, clear and dark bronze, and both are offered in every stocked length (83, 95 and 120 inch). Clear anodized reads as the standard aluminum look next to storefront and aluminum frames; dark bronze matches dark bronze anodized entrances and bronze-finish trim on the rest of the opening.
19) Will an aluminum continuous hinge hold up on a high-traffic commercial door?
The WT-FM is an aluminum extrusion, which is what keeps a 10 foot hinge from being unmanageable to hang, and it carries its load across bearings every 3 inches rather than at three points. That is the normal build for continuous hinges on offices, schools, healthcare, retail and multi-tenant residential openings. Where a spec calls out steel or stainless specifically, usually for corrosion or a wash-down area, BEST's 641 is steel and the 651 is stainless in the same full mortise configuration.
