Pemko FM-300 8FT SS – Frequently Asked Questions

1) Can a Pemko FM300 hinge be used on a fire rated door opening?
Yes. The FM300 is UL 10C certified for positive pressure fire tests and can go on fire labeled or non-fire labeled openings, so one hinge covers both the rated and unrated doors in a building. It also carries ASTM E330 and Florida Building Code approval.
2) Do I need a special door and frame prep to install a Pemko FM300 full mortise hinge?
No. The FM300 is edge-mounted into the standard full mortise hinge preparation, which is what avoids the special door and frame preparation charges you would take on other continuous hinge styles. Fasteners are custom 12-24 x 11/16 inch stainless Phillips flat head undercut TEK screws, and they are concealed when the door is closed.
3) Should I use a full mortise continuous hinge or a full surface one?
Full mortise, like the Pemko FM300, mounts into the door and frame edge so the hinge and fasteners disappear when the door is closed. That is the choice on new work or where the existing hinge prep is sound. Full surface wraps the face of the door and frame instead, and it is what you use when the door edge or frame rabbet is chewed up and you need to mount over the damage. For that case ZenSupply carries the Design Hardware FSHD full surface heavy duty geared hinge and the NGP HD5700 full surface geared hinge, which is built for 1-3/4 to 2-1/4 inch doors with a 1/16 inch door inset.
4) Will the Pemko FM300 replace anchor hinges and pivot reinforcement on an abused door?
That is what it is for. The continuous barrel carries the door over its full height, which spreads the load along the whole edge instead of concentrating it at three or five butt points. Pemko states it eliminates the need for anchor hinges, pivot reinforcement hinges, and thrust pivot units, so a sagging high-abuse door usually comes back into square on the FM300 alone.
5) Do continuous hinges like the Pemko FM300 have a handing I need to specify?
No handing to call out. The FM300 is ordered by length and finish only, in 7 foot, 8 foot, and 10 foot, satin stainless. A continuous hinge mounts to whichever edge the door swings from, so the same part covers a left hand and a right hand opening. What you do need to get right is the door thickness, 1-3/4 to 2-1/4 inches, and the length against your door height.
6) For a 1-3/4 inch to 2-1/4 inch thick door, what continuous hinges fit besides the Pemko FM300?
The Pemko Markar FM300 accommodates door thicknesses from 1-3/4 inch to 2-1/4 inch and mounts full mortise. The NGP HD5700 is stated for the same 1-3/4 inch to 2-1/4 inch door range, but it is a full surface geared hinge with a 1/16 inch door inset, so it mounts to the faces of the door and frame instead of into the door edge. Same door thickness, different prep, which makes the HD5700 the one to reach for when the leaf is the right thickness but the edge cannot be mortised.
7) What is a direct alternative to the Pemko FM300 full mortise continuous hinge from another brand?
The closest full mortise alternatives are the ABH A120HD heavy duty aluminum continuous gear hinge with Easy Install Technology and the Design Hardware FMHD full mortise heavy duty continuous geared hinge. Both mount full mortise between the door edge and the frame rabbet, the same mounting method as the Pemko Markar FM300, so the prep on the opening is the same style of prep. The difference is in the mechanism: the FM300 is a pin and barrel hinge with a 7/16 inch exterior barrel and nylon bearings in each knuckle, while the A120HD and the FMHD are geared hinges. If the specification calls out a geared continuous hinge rather than pin and barrel, those two answer it; if it calls out pin and barrel, the FM300 does.
8) The door edge and frame cannot be mortised on an existing opening. What continuous hinge can be used instead of a full mortise one?
Surface mounted continuous hinges are the answer when the door edge and frame cannot take a mortise. The Design Hardware FSHD full surface heavy duty continuous geared hinge and the BEST 664HD full surface continuous geared hinge both mount to the face of the door and frame. The ABH A460HD half surface hinge and the NGP HD5400A half surface geared hinge mount surface on one leaf and mortise on the other, which suits a retrofit where only one side of the opening can be prepped. The Pemko Markar FM300 is a full mortise hinge and needs mortise prep on both the door edge and the frame.
9) Which continuous hinges look like a substitute for the Pemko FM300 but will not drop into the same prep?
Several hinges in the heavy duty continuous class will not interchange with the Pemko Markar FM300 because the mounting differs. The Design Hardware FSOHD is a full surface offset hinge, which sets the pivot point away from the door face rather than at the door edge. The BEST 663HD is built for 3/32 inch inset doors and the NGP HD5700 is a full surface hinge with a 1/16 inch door inset, both dimensioned to a specific door to frame inset condition. The NGP HD1100A is a concealed geared hinge that hides in the opening entirely. All are continuous hinges and all are heavy duty, but none of them uses the FM300 full mortise pin and barrel prep, so swapping one in means re-prepping the opening rather than reusing what is there.
10) Which continuous hinges are ANSI/BHMA Grade 1 for a facility standard?
The Pemko Markar FM300 carries ANSI/BHMA Grade 1 certification. Among the geared continuous hinges, the NGP HD1100A concealed hinge is Grade 3. If the facility standard is written to Grade 1, the FM300 meets it directly. Grade level here describes the certified performance tier, so a Grade 3 hinge is specified against a different cycle and load basis and would need the standard rewritten to accept it.
11) What continuous hinge options are there for a 90 minute fire rated opening on a hollow metal frame?
The Pemko Markar FM300 can be used on both fire labeled and non-fire labeled openings and carries UL 10C certification for positive pressure fire tests. Among the geared hinges, the NGP HD1100A, NGP HD5400A, and NGP HD5700 are each 10C fire rated for 90 minutes on hollow metal, and the BEST 663HD and BEST 664HD are 90 minute UL fire rated. The choice among them comes down to mounting: the FM300 is full mortise, the HD5400A is half surface, and the HD5700 and 664HD are full surface. Match the mounting to what the opening can be prepped for and the fire label follows.
12) What continuous hinge covers a door taller than 8 feet?
The Pemko Markar FM300 comes in 7 foot, 8 foot, and 10 foot lengths in satin stainless steel, so a 9 or 10 foot leaf is covered by the 10 foot hinge. The geared alternatives from NGP run shorter: the HD1100A, HD5400A, and HD5700 are each 83 inches, which suits a standard 7 foot opening. For tall storefront or monumental leaves the FM300 in the 10 foot length is the one that runs the full height without splicing.
13) Is the Pemko FM300 stainless steel or aluminum?
The hinge is 304 stainless steel, supplied in a satin stainless finish. That matters on exterior and wash-down openings and in healthcare, where an aluminum-bodied hinge is the more common construction. If you want the aluminum route instead, the ABH A120HD is a full mortise aluminum continuous gear hinge.
14) Is the Pemko FM300 continuous hinge Grade 1?
Yes, ANSI/BHMA Grade 1. That is the top performance grade and the one specified for high traffic commercial openings such as schools, hospitals, and municipal buildings where a facility is standardizing on one hinge. Worth knowing when comparing: the NGP HD1100A concealed geared hinge is listed as Grade 3.
15) How wide a door will the Pemko FM300 hinge carry?
Pemko rates the FM300 for maximum door widths up to 4 feet. Past that width you are outside what this hinge is published for, and you need to look at a different continuous hinge rather than stretch it.
16) What is a good full mortise continuous hinge alternative if I need hospital tips?
The BEST 651 is a stainless steel full mortise continuous hinge with hospital tips, and the BEST 641 is the steel version, also full mortise with hospital tips. Both are listed as medium duty, so they are a step down from the heavy duty, high abuse application the Pemko FM300 is built for. Pick on whether the tip style is a facility requirement or the traffic level is.
17) Is there a lighter duty continuous hinge than the Pemko FM300 for a low traffic full mortise opening?
For a full mortise opening that does not see high traffic, the BEST 641 steel full mortise continuous hinge is a standard duty, medium duty hinge with hospital tips, and the BEST 651 is the stainless steel full mortise version, also medium duty with hospital tips. Both mount full mortise like the Pemko Markar FM300. The FM300 is built for high traffic, high abuse doors with 304 stainless steel construction and ANSI/BHMA Grade 1 certification, so for an office suite door or a low use interior opening the medium duty BEST hinges are the lighter specification. Hospital tips on the BEST hinges are a rounded end detail that avoids a square corner catching on clothing or bedding.
18) Is a geared continuous hinge the same thing as the Pemko FM300 pin and barrel hinge?
They are different mechanisms that solve the same problem of full height door support. The Pemko Markar FM300 is a pin and barrel hinge with a 7/16 inch exterior barrel and a nylon bearing in each knuckle for quiet, self lubricating operation. The ABH A120HD, ABH A135HD, ABH A210HD, ABH A460HD, the Design Hardware FMHD, FSHD and FSOHD, and the NGP and BEST HD hinges are geared hinges, which carry the load on a meshed gear set running the height of the door under a cap. Both types eliminate anchor hinges and pivot reinforcement, but the exposed profile and the prep differ, so a drawing that calls out one is not automatically satisfied by the other.
19) Which continuous hinge has a finger protection or safety feature at the hinge edge?
The ABH A135HD heavy duty aluminum continuous gear hinge is the one built with a safety design, which is the choice on schools and childcare where the gap at the hinge edge of the door is a pinch hazard. The Pemko Markar FM300 addresses a different concern at the hinge: nylon bearings in every knuckle for quiet, smooth operation, and fasteners concealed when the door is closed. On an opening where finger protection is a written requirement, the A135HD is the hinge that answers it.
20) Which continuous hinge is stainless steel rather than aluminum?
The Pemko Markar FM300 is 304 stainless steel, and the BEST 651 is a stainless steel full mortise continuous hinge. On the aluminum side, the ABH A120HD, A135HD, A210HD and A460HD are aluminum continuous gear hinges and the NGP HD5400A is aluminum alloy. The BEST 641 is steel. Material drives corrosion behavior at the opening, so exterior doors, natatoriums, kitchens and coastal sites are where the stainless choice between the FM300 and the 651 comes up, with the FM300 carrying Grade 1 and the 651 medium duty.
