Pemko CFM84SLF-HD1 – Frequently Asked Questions

1) Will the Pemko CFM84SLF-HD1 continuous hinge fit a 1-3/4 inch hollow metal door?
Yes. The FM100 full mortise continuous hinge covers door thicknesses from 1-3/4 to 2-1/4 inches, so a standard 1-3/4 inch commercial door is right in range. Maximum door width is 4 feet. Hollow metal door and frame systems are one of the applications it is built around.
2) My door opening is shorter than 84 inches. Can this Pemko continuous hinge be cut down?
It can be cut in the field. The FM100 full mortise hinge takes a minimum finished length of 79 inches and a maximum of 120 inches, so an 84 inch hinge can be trimmed down to 79 inches. Below 79 inches you need a different length, not a shorter cut.
3) Is the Pemko full mortise continuous hinge fire rated, and for how long?
UL 10C certified with a 90 minute fire rating as standard. Ordered with FirePins it goes to 180 minutes. It is also ANSI/BHMA A156.26 certified, which is the continuous hinge standard, so it satisfies both the fire assembly and the hardware spec on most commercial drawings.
4) What is the difference between a full mortise continuous hinge and a full surface or half surface one?
Full mortise means the hinge sits into prepped edges of the door and frame, so both leaves are concealed when the door is closed. That is what the Pemko FM100 short leaf flush version does, and why door faces stay flush, which matters on pairs. Full surface hinges mount on the face of the door and frame with no prep, which is the usual choice for retrofit onto an existing opening or for wrapping a damaged door edge. ZenSupply carries full surface heavy duty in the Design Hardware FSHD and the BEST 664HD, and half surface in the ABH A460HD. Pick full mortise for new doors, full surface when you cannot mortise the edge.
5) What is the closest full mortise continuous geared hinge to the Pemko CFM84SLF-HD1 from another brand?
The Design Hardware FMHD is the nearest match in configuration and duty: it is a full mortise continuous geared hinge rated heavy duty, the same mounting family as the Pemko CFM84SLF-HD1, which is a Grade 1 full mortise continuous hinge in aluminum. The ABH A120HD is a second full mortise heavy duty aluminum continuous gear hinge, built with ABH's Easy Install Technology. All three mortise into the door edge and frame rabbet rather than mounting to the door face, so an opening already prepped for one takes the others without new face prep.
6) Is there a steel or stainless continuous hinge alternative to the aluminum Pemko CFM84SLF-HD1?
Yes. The BEST 641 is a steel full mortise continuous hinge with hospital tips, and the BEST 651 is a stainless steel full mortise continuous hinge with hospital tips; both are rated medium duty. The Pemko CFM84SLF-HD1 is aluminum and rated Grade 1 heavy duty. For a wet or corrosive opening the stainless 651 is the material choice; for a high traffic opening the Pemko stays in the heavy duty class where the BEST 641 and 651 do not.
7) Which continuous hinges besides the Pemko CFM84SLF-HD1 carry a 90 minute UL 10C fire rating?
Among comparable geared hinges, the NGP HD1100A, NGP HD5400A, and NGP HD5700 are all listed as UL 10C fire rated for 90 minutes on hollow metal, and the BEST 663HD and BEST 664HD are 90 minute UL fire rated. The Pemko CFM84SLF-HD1 is UL 10C certified with a 90 minute fire rating standard, extendable to 180 minutes when ordered with FirePins. If the assembly on the drawing calls for more than 90 minutes, the Pemko with FirePins is the option in this group that reaches it.
8) Can the NGP HD1100A be used in place of the Pemko CFM84SLF-HD1 on a Grade 1 spec?
No. The NGP HD1100A is a concealed continuous geared hinge rated Grade 3, so it does not satisfy a specification written for Grade 1. The Pemko CFM84SLF-HD1 is Grade 1 and ANSI/BHMA A156.26 certified. Both are concealed-style hinges that hide the leaves when the door is closed, and both carry a 90 minute UL 10C rating on hollow metal, so the difference that matters on a Grade 1 submittal is the cycle grade, not the fire listing.
9) Will this hinge let the door swing a full 180 degrees against the wall?
Yes, 180 degree swing is what the Pemko full mortise continuous hinge is rated for. On a door that needs to clear the full opening width for gurneys or carts, look instead at a swing clear geared hinge such as the ABH A210HD, which is a full surface swing clear unit.
10) I need to standardize hinges across a healthcare facility. What comparable Grade 1 continuous hinges does ZenSupply carry?
For full mortise heavy duty, the direct alternatives to the Pemko FM100 are the ABH A120HD, which is an aluminum geared full mortise with easy install technology, and the Design Hardware FMHD. The ABH A135HD is an aluminum geared hinge with a safety design, which is the anti finger pinch style often wanted in child care and elder care. Note the grade line: the Pemko is Grade 1, while the NGP HD1100A concealed geared hinge is listed as Grade 3, so it is not a like for like substitute on a Grade 1 spec.
11) Can I get a Pemko continuous hinge shipped in a shorter box to cut freight?
Yes. The full mortise short leaf flush heavy duty hinge is offered in a PemKonnect modular version, ordered as FM_SLF_HD1-M, which packs in a 45 inch box. Same hinge, assembled on site, and it moves by standard parcel instead of oversize freight. Worth specifying if you are shipping to a jobsite with no dock.
12) Can I use this hinge on a pair of doors without the faces sticking out?
That is the reason for the short leaf flush design. On a pair, the leaves sit in the door and frame prep so both door faces stay flush with each other, and there is no protruding hinge leaf at the meeting point. Both leaves being concealed also removes the pinch point at the hinge side, which is why it turns up in child care and school specs.
13) Do I need to order a handed continuous hinge, left or right?
Continuous geared hinges like the Pemko FM100 run the full height of the door edge and are symmetrical, so there is no left hand or right hand version to specify. What you do have to get right is length, door thickness (1-3/4 to 2-1/4 inches here), and that the opening does not exceed 4 feet wide.
14) What is the difference between the Pemko CFM84SLF-HD1 and the NGP HD5700 for a 1-3/4 inch to 2-1/4 inch door?
Both cover the same door thickness range of 1-3/4 inch to 2-1/4 inch, but they mount differently. The NGP HD5700 is an 83 inch full surface continuous geared hinge with a 1/16 inch door inset, so it fastens to the face of the door and frame. The Pemko CFM84SLF-HD1 is 84 inch, full mortise, short leaf flush, and mortises into the door edge. Choose the NGP where you are retrofitting an existing door you do not want to machine, and the Pemko where a new door is being prepped and the faces need to stay flush.
15) Is the BEST 663HD a substitute for the Pemko CFM84SLF-HD1?
Not directly. The BEST 663HD is a heavy duty continuous hinge with a 90 minute UL fire rating built for 3/32 inch inset doors, so it is matched to a specific door-to-frame inset. The Pemko CFM84SLF-HD1 is a full mortise short leaf flush hinge for 1-3/4 inch to 2-1/4 inch doors where the door faces must remain flush. Both are heavy duty and 90 minute fire rated, so the deciding factor is how the door sits in the frame rather than the rating.
16) Which continuous hinge is best for a healthcare corridor door if the Pemko CFM84SLF-HD1 does not fit?
For healthcare openings, the ABH A135HD is a heavy duty aluminum continuous gear hinge built with a safety design, and the BEST 641 and BEST 651 full mortise continuous hinges are supplied with hospital tips that eliminate the ledge at the hinge ends. The Pemko CFM84SLF-HD1 conceals both leaves in its short leaf flush design and is engineered for child care, school, hospital, and elder care facilities, so all four address the same pinch and ligature concerns by different means.
17) What continuous hinge handles an offset frame condition that the Pemko CFM84SLF-HD1 cannot?
The Design Hardware FSOHD is a full surface offset heavy duty continuous geared hinge, made for openings where the door and frame do not align in the same plane. The Pemko CFM84SLF-HD1 is a full mortise hinge for a door prepped flush into the frame rabbet with a maximum door width of 4 feet. On an offset or out-of-plane condition the FSOHD is the configuration that mounts; a mortise hinge is not.
18) What finish does the Pemko 84 inch full mortise continuous hinge come in?
Clear anodized aluminum, which is the standard mill look that pairs with aluminum storefront and most hollow metal frames. Since the leaves are concealed in the full mortise short leaf flush design, the finish only reads at the hinge edge when the door is open.
