Pemko CFM83SLF138 – Frequently Asked Questions

1) Will the Pemko FM-SLF138 continuous hinge work on a 1-3/8 inch door?
That is exactly what the FM-SLF138 short leaf flush geared hinge is built for. It is a single-thickness device sized for 1-3/8 inch doors, so on a standard 1-3/4 inch commercial door it is the wrong part. If the opening is 1-3/4 inch or thicker, look at a full surface hinge like the NGP HD5700, which is listed for 1-3/4 to 2-1/4 inch doors.
2) Do I need to order a left hand and right hand version of this Pemko geared hinge?
No handing to specify. The FM-SLF138 continuous geared hinge is non-handed, so one part number covers left and right hand openings. That is one of the practical reasons a property manager standardizing across a building goes continuous: fewer part numbers to stock, and no wrong-hand returns.
3) Is the Pemko short leaf flush continuous hinge fire rated?
Yes, it carries UL 10C certification for positive pressure fire tests of door assemblies, and it is ANSI/BHMA A156.26 Grade 1. That pairing is what a spec on a fire rated opening in a school or hospital usually calls for.
4) Does the Pemko FM-SLF138 hinge get mortised into the door and frame, or does it surface mount?
Full mortise. Both leaves recess into the door edge and the frame rabbet, so the hinge is concealed when the door is closed and the mounting screws are not exposed on the pull side. That means the door and frame have to be prepped for it. If you are retrofitting an opening that is not prepped, a full surface or half surface hinge saves the machining, the ABH A460HD half surface and the Design Hardware FSHD full surface are that route.
5) How wide and how heavy a door will this Pemko continuous geared hinge carry?
Doors up to 4 feet wide. The hinge is aluminum at 1.1 pounds per foot with 3 inch bearing spacing, which is the standard duty bearing configuration, and it holds Grade 1. Continuous construction spreads the door load down the full height of the leaf instead of into three or four point hinges, which is why sagging and alignment problems stop being an issue on high traffic openings.
6) Is the NGP HD1100A a direct swap for the Pemko FM-SLF138 continuous geared hinge?
They are not the same specification. The Pemko FM-SLF138 carries a Grade 1 rating, while the NGP HD1100A concealed continuous geared hinge is listed as Grade 3. Both are concealed geared hinges, so they occupy the same place in the opening, but if the door schedule calls for Grade 1 the HD1100A will not satisfy it. Check the door thickness on the opening as well, since the FM-SLF138 is built for 1-3/8 inch doors.
7) What is the closest full mortise continuous geared hinge to the Pemko FM-SLF138 if I need a heavy duty version?
The Pemko FM-SLF138 short leaf flush hinge is an aluminum full mortise geared hinge built to Grade 1. When the opening calls for a heavy duty full mortise geared hinge instead, the ABH A120HD is an aluminum continuous gear hinge in full mortise with Easy Install Technology, and the Design Hardware FMHD is a full mortise continuous geared hinge at a heavy duty level. Both mount in the same concealed full mortise position between door and frame, so the prep concept is the same; the FM-SLF138 is the one engineered around 1-3/8 inch door thickness.
8) I need a continuous hinge for a 1-3/4 inch door, not a 1-3/8 inch door. What are my options?
The Pemko FM-SLF138 is specifically engineered for 1-3/8 inch thick doors. For a thicker door, the NGP HD5700 is a full surface continuous geared hinge with 1/16 inch door inset built for 1-3/4 inch to 2-1/4 inch doors. It is a surface applied hinge rather than a concealed full mortise one, so confirm the face clearances on the door and frame before specifying it.
9) What continuous hinge has a fire rating comparable to the Pemko FM-SLF138?
The Pemko FM-SLF138 is UL 10C certified for positive pressure fire tests of door assemblies. Among comparable geared hinges, the NGP HD1100A, NGP HD5400A and NGP HD5700 are each listed as 10C fire rated 90 minute on hollow metal, and the BEST 663HD and BEST 664HD are heavy duty continuous hinges with a 90 minute UL fire rating. Match the rating on the hinge to the label on the door assembly, and note that the BEST 663HD is built for 3/32 inch inset doors while the 664HD is a full surface geared hinge.
10) Will this Pemko hinge let the door swing a full 180 degrees back against the wall?
Yes, 180 degrees is the rated swing, and the door faces stay flush through the swing. That full range is what makes it work in bifold applications and on openings where you need the leaf pushed clear of the passage.
11) What finishes does the Pemko FM-SLF138 continuous hinge come in?
Two anodized aluminum finishes, clear and dark bronze, and both are offered in all three stocked lengths of 83, 85 and 95 inches. Clear anodized is the usual match for aluminum storefront and clear anodized frames, dark bronze for bronze storefront systems. Anodizing is part of the aluminum surface rather than a coating, so it does not chip off a door edge the way paint does.
12) Continuous geared hinge or standard butt hinges, which should I use on a high traffic commercial door?
Butt hinges concentrate the whole door load into three or four points, and on a door cycling all day those points wear, the door drops, and the latch stops lining up with the strike. A continuous geared hinge like the FM-SLF138 runs the full height of the door and carries the load along the entire leaf, so alignment holds. It is the heavier answer for entrances, corridors and classroom doors. Butt hinges remain the simpler choice on low traffic interior openings where the frame is already prepped for them.
13) I need a stainless steel continuous hinge for a hospital corridor, is this Pemko hinge the right one?
No, the FM-SLF138 is aluminum. For a steel or stainless body with hospital tips, look at the BEST 641 in steel or the BEST 651 in stainless steel, both full mortise continuous hinges. Hospital tips are the sloped ends that give nothing for a gurney, IV pole or clothing to catch on, which is why healthcare specs ask for them.
14) Will this Pemko geared hinge work on an aluminum storefront door?
Only if the door is 1-3/8 inch thick and can take a full mortise prep in the door edge and frame. The FM-SLF138 is sized for 1-3/8 inch doors and the clear anodized and dark bronze anodized finishes match common storefront framing. Many storefront doors are thinner or run a different stile arrangement, so verify the leaf thickness at the hinge stile first.
15) Which continuous hinge should I specify for a healthcare corridor instead of the Pemko FM-SLF138?
The Pemko FM-SLF138 is an aluminum full mortise geared hinge for 1-3/8 inch doors and lists healthcare institutions among its applications. Where the facility standard calls for hospital tips, 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 with hospital tips. Those are steel and stainless steel bodies rather than aluminum, and they are pin and barrel style continuous hinges rather than geared.
16) The door edge is offset from the frame face on my opening. Is there a continuous geared hinge that handles that instead of the Pemko FM-SLF138?
The Pemko FM-SLF138 is a flush full mortise hinge and assumes the door sits in a standard mortised condition with the faces flush. Where the door has to hang offset from the frame face, the Design Hardware FSOHD is a full surface offset heavy duty continuous geared hinge built for that geometry. Because it is full surface it mounts to the door and frame faces rather than into a mortise, so the existing prep does not need to be cut.
17) What is the difference between the Pemko FM-SLF138 and the ABH A135HD?
Both are aluminum continuous gear hinges. The Pemko FM-SLF138 is a short leaf flush full mortise hinge for 1-3/8 inch doors with Grade 1 construction, 3 inch bearing spacing and 180 degree swing. The ABH A135HD is a heavy duty aluminum continuous gear hinge with a safety design, which addresses the finger gap on the hinge side of the opening. If the specification is driven by a pinch protection requirement rather than by door thickness, the A135HD is the one that speaks to it.
