Pemko FS-3502 6FT 8IN SS – Frequently Asked Questions

1) Will the Pemko Markar FS3502 continuous hinge work on a 2 inch thick detention door?
Yes. The FS3502 is a full surface pin and barrel continuous hinge built specifically for 2 inch thick swing type doors, which is why it shows up on prison doors and security gates. It carries doors up to 900 lbs with a maximum door width of 4 feet, and allows swing up to 180 degrees.
2) Do I have to specify handing when ordering an FS3502 hinge?
Handing is required on the 6'8" and 7'2" lengths. The other lengths offered, 7', 8', and 10', do not call for it. If you are ordering either of those two sizes, have the door hand confirmed before the order goes in, because the hole pattern is set accordingly.
3) My existing doors are full mortise prepped. Can I use the FS3502?
No. The FS3502 mounts on the surface of the door and frame, so it does not drop into a mortised hinge prep. For a mortise application look at a full mortise continuous hinge instead, such as the BEST 651 stainless steel full mortise hinge, the ABH A120HD full mortise geared hinge, or the Design Hardware FMHD. The advantage of going full surface is that it covers up worn or damaged existing hinge preps rather than requiring new ones.
4) My door opening needs a 3 hour fire rating. Which continuous hinges qualify besides the Pemko FS3502?
The FS3502 carries fire ratings up to and including 3 hours with UL 10C certification and a Warnock Hersey listing, meeting ANSI/BHMA A156.26 at Grade 1. Among the comparable geared hinges, the NGP HD1100A, HD5400A and HD5700 are each UL 10C fire rated for 90 minutes on hollow metal, and the BEST 663HD and 664HD carry 90 minute UL fire ratings. If your assembly calls for a 3 hour rating, the FS3502 is the one in this group that reaches it.
5) My door is mortise prepped, not full surface. What should I use instead of the Pemko FS3502?
The FS3502 is a full surface hinge that mounts to the face of the door and frame with no exposed fasteners when closed, so it will not suit an opening prepped for a mortise hinge. For full mortise applications, look at the Design Hardware FMHD heavy duty continuous geared hinge, the BEST 651 stainless steel full mortise continuous hinge with hospital tips, or the ABH A120HD full mortise aluminum continuous gear hinge with Easy Install Technology. The BEST 651 is a medium duty unit; the FMHD and A120HD are heavy duty.
6) Does the Pemko FS3502 provide swing clear or ADA clearance, and what is the alternative if I need it?
The FS3502 is a standard full surface pin and barrel hinge with 180-degree maximum swing for 2" thick swing type doors; it is not a swing clear design. If you need the door leaf to clear the opening for wheelchair or gurney passage, the ABH A210HD full surface swing clear aluminum continuous gear hinge is rated to 450 lbs and is the swing clear option in the comparable group.
7) I need a continuous hinge that is hidden when the door is closed. Is the Pemko FS3502 concealed?
No. The FS3502 is a surface applied hinge; what it offers is that no mounting fasteners are exposed when the door is closed, along with optional tamper-proof security screws. If you want the hinge body itself concealed within the opening, the NGP HD1100A is a concealed continuous geared hinge in an 83" length, UL 10C fire rated for 90 minutes on hollow metal.
8) My door is 2-1/4 inches thick. Will the Pemko FS3502 work, or do I need something else?
The FS3502 is built for 2" thick swing type doors with a 1-3/4" door thickness range, so a 2-1/4" door falls outside it. The NGP HD5700 is a full surface continuous geared hinge with a 1/16" door inset that covers 1-3/4" to 2-1/4" doors and carries a UL 10C 90 minute fire rating on hollow metal, which is the full surface option to look at for that thickness.
9) What lengths does the Pemko FS3502 hinge come in, and can I get it cut for an odd door height?
Stock lengths are 6'8", 7', 7'2", 8', and 10', all in satin stainless steel. Custom lengths and custom hole patterns are also available, which is how extremely tall doors get covered.
10) Can a full surface hinge like the FS3502 be tampered with from the corridor side?
No exposed mounting fasteners are visible when the door is closed, and tamper-proof security screws are available as an option. That is the reason this hinge gets specified in correctional facilities and secure government buildings rather than a standard full surface hinge.
11) Are fasteners included with the Pemko FS3502 hinge or do I need to supply my own?
Custom #12-24 x 7/16" PFHMS fasteners ship with the hinge, and the hole pattern is symmetrically templated so it lines up without field layout. Hospital tip is standard. If you want the tamper-proof security screws instead, those are a separate option to add.
12) How does the FS3502 compare to the NGP HD5700 full surface hinge for a 2 inch door?
Different jobs. The NGP HD5700 is a full surface geared hinge with a 1/16" door inset sized for 1-3/4" to 2-1/4" doors, rated 90 minutes on hollow metal. The Pemko FS3502 is a pin and barrel hinge in 12 gauge 304 stainless, set up for 2 inch swing type doors, rated to 900 lbs and fire rated up to 3 hours. For a standard commercial 2 inch door the HD5700 covers it; for detention weight or a 3 hour assembly, the FS3502 is the one that qualifies.
13) Is the FS3502 suitable for a door wider than 4 feet?
No. Maximum door width for the FS3502 is 4'0". Beyond that width the load geometry falls outside what the hinge is rated for, regardless of door weight.
14) Is there a lighter duty continuous hinge than the Pemko FS3502 for a standard commercial interior door?
The FS3502 is built for correctional and high-security openings, with 12 gauge 304 stainless steel construction and a 900 lb rating. For a standard commercial interior opening that does not need that capacity, the BEST 641 steel full mortise continuous hinge with hospital tips and the BEST 651 stainless steel full mortise continuous hinge with hospital tips are both medium duty units. Both are full mortise, so the door and frame prep differs from the face-mounted FS3502.
15) What should I use if the FS3502 mounts to the face of the door but I need a half surface hinge?
The FS3502 mounts full surface, to the face of both the door and the frame. When the frame side needs to be mortised and only the door side surface mounted, the half surface options are the ABH A460HD heavy duty aluminum continuous gear hinge rated to 450 lbs and the NGP HD5400A 83" half surface continuous geared hinge in aluminum alloy, which carries a UL 10C 90 minute fire rating on hollow metal. The FS3502 carries fire ratings up to and including 3 hours with UL 10C certification.
16) I need a continuous hinge with a finger guard or safety edge. Does the Pemko FS3502 have one?
The FS3502 is a pin and barrel hinge with a hospital tip as standard and a symmetrically templated hole pattern; its design focus is tamper resistance for correctional and high-security openings rather than pinch protection. For a hinge built around a safety design, the ABH A135HD heavy duty aluminum continuous gear hinge is the option in this group. It is a different mounting type from the full surface FS3502, so confirm the door and frame prep before substituting.
17) I need a continuous hinge longer than 83 inches for a tall door. Which options cover that?
The Pemko Markar FS3502 is offered in 6'8", 7', 7'2", 8' and 10' lengths in satin stainless steel, with custom lengths and hole patterns available and handing required on the 6'8" and 7'2" lengths. By comparison the NGP HD1100A, HD5400A and HD5700 are each cataloged at 83 inches. For extremely tall doors, the FS3502 range is the one that runs past a standard 7 foot opening.
18) Will a 12 gauge stainless hinge hold up in a wet or corrosive environment like a car wash or coastal facility?
The FS3502 is 12 gauge 304 stainless steel with stainless steel end pins, so corrosion resistance is built into the material rather than a coating. The finish offered is satin stainless steel.
