Pemko FM-400 54IN C – Frequently Asked Questions

1) Will the Pemko Markar FM400 continuous hinge work on 1 inch thick toilet partition doors?
Yes. The FM400 Series full mortise spring loaded continuous hinge covers door thicknesses from 1 inch through 1-3/4 inches, which spans the usual range of partition panel stock, from thin laminate and powder-coated steel doors up to solid phenolic. Maximum door width it is rated for is 3 inches and the swing is 90 degrees.
2) What lengths does the Pemko Markar FM400 continuous hinge come in, and can I get one cut for a non-standard partition door?
Stock lengths are 54 inches, 57 inches, and 72 inches, all in clear anodized aluminum. Custom lengths are made from 24 inches up to 72 inches, so an odd-height partition door or a short pilaster-mounted panel can be covered without splicing two hinges together. Measure the door leaf height, not the pilaster.
3) Do I have to order a left hand and a right hand version of the FM400 partition hinge?
No. The FM400 is non-handed, so one part number covers both swings. For a facility manager stocking spares across a building of restrooms, that means a single shelf item rather than a handed pair, and no chance of an installer opening the wrong box at the stall.
4) Why use a continuous hinge on a toilet partition instead of standard butt hinges?
Two reasons that matter in a restroom. A continuous hinge runs the full length of the door leaf, so the load and the abuse are spread down the whole edge instead of concentrating at two or three knuckles, which is where partition doors normally fail. And it closes the sightline at the hinge edge, which is the gap people complain about for privacy. Butt-type spring hinges like the Hager 1150 or the McKinney 1502 do the closing job but leave that gap open and put all the stress on the leaves.
5) Does a full mortise continuous hinge like the FM400 need the partition door and pilaster machined out?
Yes, full mortise means both leaves set into prepared pockets, one in the door edge and one in the pilaster, so the hinge sits flush rather than surface applied. On a retrofit that is the thing to check before ordering: if the existing partition was set up for surface mounted gravity hinges and has no mortise prep, you are cutting the door and pilaster to take this hinge. New partition orders can be specified with the prep from the factory.
6) What is the difference between the Pemko FM400 continuous hinge and a Hager 1250 full mortise spring hinge?
Both are full mortise spring hinges, but they are different form factors. The FM400 is a continuous hinge running the full height of the door in lengths of 54 inches, 57 inches and 72 inches, built from aluminum alloy with extruded aluminum covers, closing doors up to 80 lbs on 1 inch to 1-3/4 inch thicknesses. The Hager 1250 is a full mortise spring hinge in standard weight steel construction at a medium duty level, installed as individual leaves in separate hinge cutouts rather than as one continuous piece. Choose the continuous form when you want stress spread along the whole door edge and no sightline gap at the hinge; choose the individual mortise hinge when the door is already prepped for discrete hinge locations.
7) The toilet partition doors need rounded hinge corners to match the existing prep - what spring hinge fits that?
The Pemko Markar FM400 is a full-length continuous hinge and is mortised as one full-height piece, so corner radius does not apply to it. For doors already prepped with radiused hinge pockets, Hager offers the 1251 full mortise spring hinge with 1/4 inch round corners and the 1252 with 5/8 inch round corners, both standard weight steel at medium duty. Orca Hardware covers the same shapes in 4 inch by 4 inch sizes: the SPR4014 with 1/4 inch radius corners and the SPR4058 with 5/8 inch radius corners.
8) The doors are 1-3/4 inches thick and the architect wants concealed hardware - what is the alternative to the Pemko FM400?
The Pemko Markar FM400 accepts 1 inch to 1-3/4 inch doors and shows as an extruded aluminum cover along the full hinge edge. For a concealed look on a 1-3/4 inch door, the SOSS 218IC is a 7 inch heavy duty invisible spring closer hinge with a 1-3/4 inch minimum door thickness, so it fits that thickness where the FM400 sits at the top of its range. Stepping to a 2 inch or thicker door, the SOSS 220IC is the 7 inch invisible spring closer with a 2 inch minimum thickness and a 20 minute fire rating.
9) Is the Pemko FM400 hinge going to corrode in a wet commercial restroom?
The FM400 is built from aluminum alloy with extruded aluminum covers, and the stock finish is clear anodized aluminum. Anodized aluminum is the standard answer for humid, frequently washed-down restroom environments because it does not rust the way a plated steel butt hinge will where mop water and cleaners hit the bottom of the door.
10) Which spring hinge should I use for a regular commercial door rather than a toilet partition?
The FM400 is built around partition geometry, doors up to 3 inches wide with a 90 degree swing, so it is the wrong tool for a full size opening. For a standard commercial door, a full mortise butt spring hinge is the usual choice: the Hager 1150 in stainless steel or the Hager 1250 in steel, both standard weight medium duty, or the McKinney 1502 in a 4-1/2 by 4-1/2 square corner. If the door needs to swing both ways, the Deltana DASH95 is a double action spring hinge.
11) I need a self closing hinge that stays hidden when the door is shut. Is the FM400 that, or is there something else?
Different idea. The FM400 is visible as a full length aluminum strip down the hinge edge, which is what lets it kill the sightline on a partition. If you want the closer completely concealed in a swinging door, look at the SOSS invisible spring closer hinges instead: the 216IC and the 220IC, both heavy duty, and the 218IC at 7 inches with a 1-3/4 inch minimum door thickness. The 220IC is also 7 inches and needs a 2 inch minimum door thickness.
12) Can I standardize one continuous hinge across all the stall doors in a building with mixed partition thicknesses?
In most cases yes. Because the FM400 takes anything from 1 inch to 1-3/4 inches thick and is non-handed, one hinge type covers stalls with different door stock and different swings across a facility. What will vary between openings is length. Doors are commonly 54 or 57 inches, and anything outside that is a custom length between 24 and 72 inches, so build the order by door height and keep the hinge model constant.
13) What should I use instead of the Pemko FM400 if I want a hinge I can take the pin out of to remove the door?
The Pemko Markar FM400 is a continuous hinge running the full length of the door, so the door is removed by unfastening the hinge rather than pulling a pin. If servicing means lifting the door off in seconds, the BEST 2060R is a plain bearing spring hinge with a removable pin in square corners, standard weight, and the BEST RD2060R is the same removable pin plain bearing spring hinge in a radius corner. Both are medium duty and install as individual full mortise leaves.
14) Is a double action saloon hinge a substitute for the Pemko FM400 on a partition door?
No, they solve different problems. The Pemko Markar FM400 is a single direction spring loaded continuous hinge with 90 degree swing capability, non-handed, sized for partition doors up to 3 inches wide in the hinge stile and up to 80 lbs. The Deltana DASHS is a double action saloon hinge in 4 inch, 5 inch and 6 inch heights, and the Deltana DASH95 is a double action spring hinge with solid brass cover plates. Double action means the door swings both directions and self centers, which is a cafe or saloon door behavior, not the one way swing and full height gap free hinge edge a toilet partition uses.
15) What is a simpler spring hinge alternative to a full length continuous hinge for a light partition or utility door?
Where the full height mortise of the Pemko Markar FM400 is more prep than the opening needs, individual spring hinges do the closing job at discrete locations. The McKinney 1502 is a square corner full mortise standard weight spring hinge at 4-1/2 inches by 4-1/2 inches, medium duty. Orca Hardware SPR4040 is a 4 inch by 4 inch square corner spring hinge, also medium duty. The trade off is that stress concentrates at the individual hinge points and there is a visible sightline at the hinge edge, which the continuous form eliminates.
16) Will the FM400 hold a stall door open, or does it always return it to closed?
It always returns to closed. The FM400 is a spring loaded hinge, so the closing force is built into the hinge itself and there is no hold open. In a restroom that is generally what is wanted, since the door showing shut is the privacy cue. If you need a door that can be parked open, a spring hinge of any kind is the wrong choice.
