Pemko CSPFM83SLF-HD1 – Frequently Asked Questions

1) Will a Pemko SPFM-SLF continuous hinge work on a door with weatherstrip or a thermal break in the frame?
That's the reason this version exists. The SPFM-SLF is a short leaf flush full mortise geared hinge, so the leaf stays out of the way of weatherstrip, thermo-break, or an applied frame stop that a standard-leaf continuous hinge would run into. If your frame is a plain hollow metal profile with nothing applied at the hinge jamb, a standard full mortise geared hinge covers you; the short leaf flush is for the openings where something is already occupying that space.
2) What door thickness does the Pemko SPFM-SLF geared continuous hinge fit?
1-3/4 inch through 2-1/4 inch doors. That covers the standard 1-3/4 inch commercial door and the thicker thermally broken and insulated exterior doors where this hinge usually ends up. Doors thinner than 1-3/4 inches are outside the range, so a 1-3/8 inch interior door needs a different hinge.
3) How wide and how tall a door will the SPFM-SLF continuous hinge carry?
Door widths up to 4 feet, and hinge lengths run to a maximum of 10 feet, with a 79 inch minimum. Stocked lengths are 83, 85, 95 and 120 inches, and custom lengths are made for openings that don't land on one of those. Anything wider than a 4 foot leaf is past what this hinge is rated to carry.
4) Can the Pemko SPFM-SLF be used on a fire rated door opening?
It is UL 10C certified. On 3-Hour A-Label assemblies, special FirePins are required and have to be ordered with the hinge; below that label the hinge goes on as-is. The hinge also complies with ANSI/BHMA A156.26, the standard for continuous hinges.
5) Is a full mortise continuous hinge like the Pemko SPFM-SLF the right choice, or should I use a full surface or half surface hinge?
Full mortise means the hinge sets into the edge of the door and the rabbet of the frame, so it needs both prepped and it disappears when the door is closed. That's the choice on new doors and frames, or a retrofit where the existing prep is already cut for it. If you're hanging a hinge on a door and frame you don't want to machine, or the door edge is chewed up, a full surface hinge mounts to the faces instead: the Design Hardware FSHD or the NGP HD5700 are full surface heavy duty geared hinges. A half surface option like the NGP HD5400A mortises into the frame and surface mounts to the door face. Full mortise is the cleanest look; full surface is the easier install on an existing opening.
6) What is the closest equivalent to the Pemko SPFM-SLF if I need a full mortise continuous geared hinge from another brand?
The Pemko SPFM-SLF is a Grade 1 heavy duty full mortise continuous geared hinge in aluminum. The closest same-configuration peers are the Design Hardware FMHD, a heavy duty full mortise continuous geared hinge, and the ABH A120HD, a heavy duty aluminum continuous gear hinge in full mortise with Easy Install technology. Both mount into the mortised edge of the door and frame the same way the SPFM-SLF does. The difference to check before you swap is the leaf: the SPFM-SLF uses a short leaf flush configuration specifically so the leaf does not run into weatherstrip, thermo-break, or an applied frame stop, and neither peer is described with that short leaf geometry.
7) I need a continuous geared hinge on a 90 minute fire rated opening. Does the Pemko SPFM-SLF work or should I use something else?
The Pemko SPFM-SLF is UL 10C certified, with special FirePins required only on 3-hour A-Label assemblies, so a 90 minute opening does not call for the FirePins. If you would rather specify a hinge whose fire rating is stated at 90 minutes directly, the BEST 663HD is a heavy duty continuous hinge with a 90 minute UL fire rating for 3/32 inch inset doors, the BEST 664HD is the full surface heavy duty geared hinge with a 90 minute UL rating, and the NGP HD5700 is a full surface geared hinge listed 10C fire rated 90 minute on hollow metal. Confirm the inset your door actually has before choosing between them.
8) The NGP HD1100A is also called a heavy duty Grade 1 continuous geared hinge. Is it the same thing as the Pemko SPFM-SLF?
They are not the same. The Pemko SPFM-SLF is a Grade 1 aluminum full mortise hinge with a short leaf flush design that clears weatherstrip, thermo-break, and applied stops. The NGP HD1100A is a concealed continuous geared hinge, and its stated grade is Grade 3, with a 10C 90 minute fire rating on hollow metal. Concealed means the hinge is hidden in the gap when the door is closed rather than showing a mortised leaf, so the frame preparation and the finished appearance are different, and the grade is not a match if your specification calls for Grade 1.
9) I need wheelchair clearance through the opening. Will the Pemko SPFM-SLF give me that, or do I need a swing clear hinge?
The Pemko SPFM-SLF is a full mortise hinge with 180 degree maximum swing and 5/16 inch minimum clearance, but the door still parks against the frame face at full open, so the leaf of the frame reduces the clear opening width. Where you need the door to swing completely out of the opening, the ABH A210HD is a full surface swing clear heavy duty aluminum continuous gear hinge rated at 450 lbs. Swing clear geometry carries the door past the frame so the full rough opening is usable, which is the usual answer on patient room and accessible corridor doors.
10) Do I need to specify left hand or right hand on a Pemko SPFM-SLF hinge?
No handing to call out. The SPFM-SLF is non handed, so one part number covers both swings and a property manager stocking spares only has to carry one length per door height rather than a left and a right.
11) What fasteners come with a Pemko continuous geared hinge, and do I need anything else to install it?
Self drilling Teks fasteners are the standard supply, which is what you want going into hollow metal door and frame. Wood screws are available on request for wood doors or wood frames, so specify those at the time of order if that's the opening. The one other line item to remember is FirePins, and only on a 3-Hour A-Label assembly.
12) I need a continuous hinge for a healthcare corridor door. Is the Pemko SPFM-SLF the one, or is there something better suited?
The SPFM-SLF is a Grade 1 aluminum geared hinge and it will take corridor traffic, but its short leaf flush profile is aimed at frames with weatherstrip or a thermal break, which is an exterior condition more than an interior one. For interior patient and corridor doors, the BEST 641 in steel and the BEST 651 in stainless are full mortise continuous hinges with hospital tips, which is the detail specified in healthcare to keep the hinge from catching. Both are medium duty. If the opening is an exterior weatherized entrance, stay with the Pemko.
13) Will a Pemko geared continuous hinge hold up better than the pair of butt hinges that keep sagging on my entry door?
A continuous geared hinge runs the full height of the door and spreads the load along the entire edge instead of concentrating it at two or three points, which is what causes butt hinges to pull and the door to drop. The SPFM-SLF is Grade 1 aluminum, rated at 1.13 lbs per foot, and carries doors up to 4 feet wide at 1-3/4 to 2-1/4 inch thickness. On a high traffic entrance that's already failed once on butts, this is the fix.
14) Is there a lighter duty continuous hinge for an interior opening that does not need Grade 1?
The Pemko SPFM-SLF is a Grade 1 heavy duty hinge built for high traffic commercial openings. For an interior door that does not carry that load, 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 keep the full mortise mounting, so the frame prep concept is the same, and both are steel rather than the aluminum the SPFM-SLF uses. Hospital tips give a sloped end cap that will not catch clothing or IV lines, which matters in patient care corridors.
15) What continuous hinge do I use when the door and frame faces do not line up flush?
The Pemko SPFM-SLF is a full mortise hinge, so it assumes the door sits into the frame and gets machined edge prep. When the door face stands proud of the frame or the two planes do not align, the offset surface hinge is the fix: the Design Hardware FSOHD is a full surface offset heavy duty continuous geared hinge. The offset leaf takes up the difference between the two mounting planes instead of requiring shims. If the faces do line up and you simply cannot mortise, the non-offset Design Hardware FSHD full surface heavy duty geared hinge is the straighter swap.
16) Is there a continuous geared hinge with a finger safety feature instead of the Pemko SPFM-SLF?
The Pemko SPFM-SLF is a Grade 1 heavy duty aluminum geared hinge in a short leaf flush full mortise configuration; its design intent is weatherstrip and thermo-break clearance rather than hinge-side pinch protection. Where finger safety on the hinge side is the requirement, typically schools, daycare, and memory care, the ABH A135HD is a heavy duty aluminum continuous gear hinge with a safety design. Both are heavy duty aluminum geared hinges, so the load class is comparable; the mounting prep is what you should verify against the opening.
17) My doors are 1-3/4 inch. Which continuous geared hinges cover that thickness besides the Pemko SPFM-SLF?
The Pemko SPFM-SLF accommodates door thicknesses from 1-3/4 inch to 2-1/4 inch, with maximum door widths up to 4 feet and hinge lengths up to 10 feet. Among the geared peers, the NGP HD5700 is a full surface continuous geared hinge with 1/16 inch door inset covering the same 1-3/4 inch to 2-1/4 inch range, in an 83 inch length. The thickness window matches; the mounting does not, since the HD5700 goes on the faces rather than into a mortise, and the SPFM-SLF reaches longer lengths for tall openings.
18) What finishes does the Pemko SPFM-SLF continuous hinge come in, and can I match the other doors in my building?
Seven finishes: clear anodized aluminum, dark bronze anodized aluminum, dark oxidized satin bronze equivalent, plus black suede, white suede, satin nickel and gold powder coat. Clear anodized and dark bronze anodized are the two that match standard aluminum storefront and entrance framing, which is where most of these hinges land. The suede powder coats are there when the hinge has to disappear into a painted frame instead. Every one of the seven is offered in all four stocked lengths.
19) Is the Pemko SPFM-SLF rated for commercial use or is it a residential hinge?
Commercial. It's a Grade 1 aluminum geared hinge built for commercial office entrances, schools, healthcare, retail, warehouse and municipal buildings, and it complies with ANSI/BHMA A156.26. Grade 1 is the top performance tier in the ANSI/BHMA grading, which is what a spec on a commercial job will normally call for.
