Pemko HS-303 6FT 8IN SS – Frequently Asked Questions

1) Can I install the Pemko HS303 continuous hinge in the holes left by the old butt hinges?
That is exactly what it is built for. The HS303 half surface pin and barrel hinge fits into the gaps left after standard butt hinges are removed, so it goes onto an existing opening for hinge repair and replacement without a new frame. Fasteners included are custom 12-24 x 11/16 inch stainless Phillips flat head undercut TEK screws and 1/4-14 x 3/4 inch security TORX TEK screws.
2) Is the Pemko HS303 hinge fire rated for a labeled opening?
Fire rated up to and including 3 hours, with UL 10C certification. It is approved for both fire-labeled and non-labeled openings, which is what makes it usable on corridor and stair doors in schools, hospitals, and government buildings.
3) What length continuous hinge do I need for a 7 foot door?
The HS303 comes in five stock lengths: 6 feet 8 inches, 7 feet, 7 feet 2 inches, 8 feet, and 10 feet. Match the length to the door leaf height, so a standard 7 foot door takes the 7 foot hinge. Custom lengths are available when a door falls outside those sizes.
4) Can I use the Pemko HS303 hinge to reverse the handing or swing of a door?
Yes. The HS303 is meant for reversing door handing or swing direction in evenly rabbeted frames, and it gives 180 degree swing. That is a common fix when a door needs to swing out for egress and you do not want to replace the frame.
5) I need a 3 hour fire rated continuous hinge. Is a 90 minute geared hinge a substitute?
Not for a 3 hour labeled opening. The HS303 pin and barrel hinge is rated up to 3 hours under UL 10C. The half surface geared alternative, the NGP HD5400A, is listed at 90 minutes on hollow metal, as are the BEST 663HD and 664HD. Those cover 90 minute doors, but they will not satisfy a 3 hour label.
6) What is the closest half surface continuous geared hinge to the Pemko Markar HS303 if I need a different mounting family?
The HS303 is a half surface continuous pin and barrel hinge in 304 stainless steel with extruded aluminum covers, Grade 1, fire rated up to and including 3 hours with UL 10C. The closest same-mount alternates are the NGP HD5400A half surface continuous geared hinge, an aluminum alloy hinge in an 83 inch length rated UL 10C 90 minute on hollow metal, and the ABH A460HD heavy duty aluminum continuous gear hinge, also half surface with a 450 lbs capacity. The main working differences are the hinge mechanism, pin and barrel on the HS303 versus geared on the two alternates, and the fire duration, 3 hours on the HS303 versus 90 minute on the HD5400A.
7) The frame is not rabbeted for a half surface hinge and the door is being replaced anyway. What continuous hinge should I use instead of the Pemko HS303?
The HS303 is built to drop into the gap left after standard butt hinges are removed on evenly rabbeted frames, so a full mortise hinge is the different-prep answer. The ABH A120HD is a heavy duty aluminum continuous gear hinge in full mortise, the Design Hardware FMHD is a heavy duty full mortise continuous geared hinge, and the BEST 651 is a stainless steel full mortise continuous hinge with hospital tips. Full mortise means the frame and door edge are routed for the hinge rather than surface fastened over the existing prep.
8) I need a 3 hour fire rated continuous hinge. Which continuous hinges carry that and which stop short?
The Pemko Markar HS303 carries fire ratings up to and including 3 hours with UL 10C certification, on both fire labeled and non labeled openings. Among the geared alternates, the NGP HD5400A, NGP HD5700, and NGP HD1100A are each 10C fire rated 90 minute on hollow metal, and the BEST 663HD and BEST 664HD are 90 minute UL fire rated. If the opening is labeled for more than 90 minutes, the HS303 is the one in this group written to that duration.
9) Is a full surface continuous hinge the same thing as the Pemko HS303 half surface?
No. The HS303 is half surface, meaning one leaf mounts to the surface and the other sits in the existing butt hinge prep. Full surface hinges mount both leaves on the face of the door and frame and are a different prep entirely. Full surface options include the Design Hardware FSHD heavy duty full surface continuous geared hinge, the BEST 664HD heavy duty full surface continuous geared hinge, and the NGP HD5700 full surface continuous geared hinge with 1/16 inch door inset for 1-3/4 inch to 2-1/4 inch doors. Ordering one of those against an HS303 opening leaves you with the wrong leaf geometry at the frame.
10) I need wheelchair clearance at the opening, not just a hinge replacement. What continuous hinge do I use instead of the HS303?
The HS303 gives 180 degree swing but the door still stops against the frame face in the normal way. For clear opening width, the ABH A210HD is a heavy duty aluminum continuous gear hinge in full surface swing clear, which carries the door out of the opening when swung, and it is rated to 450 lbs capacity. Swing clear is a full surface mount, so it is a different frame prep from the HS303 half surface retrofit.
11) The door is 2 inches thick. Is the Pemko HS303 the right continuous hinge?
The HS303 is designed for 1-3/4 inch door thickness. For a thicker leaf, the NGP HD5700 full surface continuous geared hinge is built with a 1/16 inch door inset for 1-3/4 inch to 2-1/4 inch doors, which covers a 2 inch door. Note that the HD5700 is full surface rather than half surface, so it mounts to both faces instead of into the existing butt hinge prep, and it is 10C fire rated 90 minute on hollow metal.
12) Is a half surface continuous hinge the right choice, or should I use full mortise or full surface?
Half surface means one leaf mortises into the frame and the other surface mounts to the door face, so it works when the frame prep is good but the door edge is chewed up, which is the usual retrofit case. Full mortise hinges like the Design Hardware FMHD or BEST 651 need both the door and frame machined, so they suit new doors. Full surface, such as the Design Hardware FSHD or BEST 664HD, mounts entirely on the faces and is the choice when neither the door nor the frame will take a mortise.
13) Will the Pemko HS303 hold up in a high traffic entrance or a school corridor?
It carries a BHMA Grade 1 rating, which is the top commercial durability tier, and the hinge material is 304 stainless steel with extruded aluminum covers. Grade 1 continuous hinges are the standard specification for high cycle openings in schools, healthcare, retail, and industrial buildings.
14) Can someone unscrew the Pemko HS303 hinge from outside when the door is closed?
No. The fasteners are concealed when the door is closed, and the door side uses security TORX TEK screws. That is the point of a continuous hinge on a secured opening: there is no removable pin and nothing to attack from the pull side.
15) I have an 8 foot tall door. Can I get a continuous hinge that long?
Yes. The HS303 is stocked in 8 foot and 10 foot lengths for tall openings, past the usual 7 foot and 7 foot 2 inch commercial sizes. Anything beyond that can be ordered as a custom length.
16) Do I need to buy screws or anchors separately for the Pemko HS303 hinge?
No, the fastener package ships with the hinge: custom 12-24 x 11/16 inch stainless Phillips flat head undercut TEK screws, 1/4-14 x 3/4 inch security TORX TEK screws, and additional fasteners. TEK screws are self drilling, so on a hollow metal frame and door you are not pre-tapping.
17) I am standardizing continuous hinges across a hospital. Which have hospital tips and how does the Pemko HS303 fit in?
The BEST 641 steel full mortise and BEST 651 stainless steel full mortise continuous hinges are both built with hospital tips, both at a medium duty level. The Pemko Markar HS303 is the heavier retrofit piece for the same facility type, Grade 1 in 304 stainless with fire ratings up to and including 3 hours under UL 10C, half surface so it drops into existing butt hinge prep on openings you are not reframing. Healthcare institutions are among its stated applications.
18) My opening needs a 10 foot hinge. The NGP continuous hinges I keep finding are 83 inches. What are my options?
The Pemko Markar HS303 comes in 6'8", 7', 7'2", 8', and 10' lengths in satin stainless steel, with custom lengths available for requirements beyond standard sizing. The NGP HD5400A, HD5700, and HD1100A are each cataloged at 83 inches, which is short of a 10 foot opening. For tall openings the HS303 length range is the one to work from.
19) What is the difference between the Pemko HS303 and the Design Hardware FSOHD offset hinge?
The HS303 is a half surface pin and barrel hinge that fits the gap left by removed butt hinges and gives 180 degree swing. The Design Hardware FSOHD is a heavy duty full surface offset continuous geared hinge. Offset full surface geometry sets the pivot line away from the door face, which suits openings where the door has to clear a projecting frame or wall condition, and it mounts to both faces rather than into the existing hinge prep.
20) Does a geared continuous hinge work the same as the Pemko HS303?
They mount in the same family of applications but the mechanism differs. The HS303 is a continuous pin and barrel hinge in 304 stainless steel with extruded aluminum covers, running the full height of the door on a pin. The ABH A460HD, ABH A135HD, Design Hardware FSHD and FMHD, and the NGP HD5400A are continuous geared hinges, where interlocking gear teeth in an aluminum extrusion carry the leaf motion. Pin and barrel and geared are not interchangeable at the same prep, so confirm which one the existing opening was built for before substituting.
21) Which continuous hinge should I look at if finger safety at the hinge edge is a requirement?
The ABH A135HD is a heavy duty aluminum continuous gear hinge built with a safety design, which is the one in this group addressed to the hinge edge safety condition found in schools and childcare spaces. The Pemko Markar HS303 is a half surface pin and barrel hinge with extruded aluminum covers and fasteners concealed when the door is closed, Grade 1 and fire rated up to and including 3 hours, which is the choice when the driver is retrofit into existing butt hinge prep and fire duration rather than edge protection.
22) What finish does the Pemko HS303 continuous hinge come in?
Satin stainless steel, across every length. If you are standardizing a building on one look, all five sizes match, so a 6 foot 8 inch opening and a 10 foot opening will read the same down the corridor.
23) Will the Pemko HS303 corrode on an exterior or wash-down door?
The hinge material is 304 stainless steel, with extruded aluminum covers. 304 is the standard corrosion resistant stainless used on commercial door hardware, which is why it turns up on exterior entrances, kitchens, and healthcare openings that get cleaned hard.
