Pemko CHS83SF-HD1 – Frequently Asked Questions

1) Will the Pemko HS-SF-HD1 continuous hinge work on a 2-inch thick door?
Yes. The HS-SF-HD1 half surface geared hinge covers door thicknesses from 1-3/4 inches through 2-1/4 inches, so a 2 inch door sits in the middle of the range. Maximum door width is 4 feet. If your door is thinner than 1-3/4 inches, this is the wrong hinge.
2) What is a half surface continuous hinge and when should I use one instead of full mortise?
A half surface hinge mortises into the frame and surface mounts to the door face, which is why Pemko positions the HS-SF-HD1 for retrofit work: it avoids the need for special hinge reinforcements and works with standard hollow metal door and frame prep. Full mortise hinges cut into both leaves and are usually the choice on new hollow metal openings; a full surface version mounts to the face of both door and frame and is what you want when neither leaf can be routed. If you are doing a new-construction full mortise opening, look at the Design Hardware Full Mortise heavy duty geared hinge instead.
3) Can I use this hinge on a fire door?
The HS-SF-HD1 is approved for use on swinging type fire doors. On 3-hour (A-Label) assemblies you also have to order special FirePins; below that level no FirePins are called for.
4) What lengths does the Pemko HS-SF-HD1 come in, and what if my door is taller?
Stock lengths are 83, 85, 95 and 120 inches, each in Clear Anodized or Dark Bronze Anodized aluminum. The series runs from a 79 inch minimum up to a 10 foot maximum, and custom lengths are made for specific openings, so a door taller than 120 inches can still be covered up to 10 feet.
5) How much clearance does the door need to swing with this hinge?
Plan on 21/32 inch minimum hinge clearance. With that clearance the HS-SF-HD1 gives a full 180 degree swing. Tight jamb conditions, applied stops or wall returns that eat into that clearance will limit how far the door opens.
6) What is the closest half surface continuous geared hinge to the Pemko HS-SF-HD1 from another brand?
The ABH A460HD is the nearest half surface alternative — an aluminum continuous gear hinge in half surface mount, rated to 450 lbs capacity. The NGP HD5400A is another half surface continuous geared hinge in aluminum alloy, offered in an 83 inch length and 10C fire rated for 90 minutes on hollow metal. The Pemko HS-SF-HD1 is Grade 1 aluminum and comes in 83, 85, 95 and 120 inch lengths in clear anodized or dark bronze anodized. If you are matching an existing half surface prep, all three mount to the door face and frame rabbet rather than requiring a mortised edge prep.
7) My opening has no half surface prep and the door edge can be mortised — what should I use instead of the HS-SF-HD1?
Go to a full mortise continuous geared hinge. The ABH A120HD is a heavy duty aluminum continuous gear hinge in full mortise with Easy Install Technology, and Design Hardware's FMHD is a heavy duty full mortise continuous geared hinge. Either mortises into the door edge and frame rabbet so no hardware shows on the door face, where the Pemko HS-SF-HD1 is half surface and was designed for retrofit work where you do not want to cut the door.
8) Can I use the HS-SF-HD1 on a door I cannot cut at all, including the frame rabbet?
If neither the door edge nor the frame rabbet can be prepped, a full surface hinge is the better route — it mounts entirely to the faces of the door and frame. The Design Hardware FSHD is a heavy duty full surface continuous geared hinge, the BEST 664HD is a heavy duty full surface continuous geared hinge with a 90 minute UL fire rating, and the NGP HD5700 is a full surface geared hinge with 1/16 inch door inset for 1-3/4 inch to 2-1/4 inch doors. The Pemko HS-SF-HD1 is half surface, which still engages the frame rabbet, and it covers the same 1-3/4 inch to 2-1/4 inch door thickness range.
9) I need a documented 90 minute UL fire rating on the hinge itself — what are my options alongside the Pemko HS-SF-HD1?
Peers that state a fire rating outright are the BEST 663HD, a heavy duty continuous hinge listed 90 minute UL fire rated for 3/32 inch inset doors, the BEST 664HD full surface heavy duty with a 90 minute UL rating, and the NGP HD5400A and HD5700, both 10C fire rated 90 minute on hollow metal. The Pemko HS-SF-HD1 is approved for swinging type fire doors, with special FirePins required only on 3-hour A-label assemblies, and it meets ANSI/BHMA A156.26.
10) Does the NGP HD1100A carry the same Grade 1 rating as the Pemko HS-SF-HD1?
No. The NGP HD1100A is a concealed continuous geared hinge, offered at 83 inches, listed Grade 3 and 10C fire rated 90 minute on hollow metal. The Pemko HS-SF-HD1 is Grade 1 aluminum. It is also a different mounting family — the HD1100A is concealed within the opening, while the Pemko is half surface and mounts to the door face for retrofit. If the drawing calls Grade 1, the HD1100A will not satisfy it.
11) Why is this called a safety hinge for child care and nursing facilities?
Geared continuous hinges close off the gap along the full hinge edge rather than leaving the open pinch point you get between butt hinges. Pemko builds the HS-SF-HD1 specifically for retrofit in child care and nursing facilities for that reason, and the half surface mount means you can add it to existing hollow metal openings without new reinforcements.
12) What other half surface continuous geared hinges could I use instead of the Pemko HS-SF-HD1?
The closest same-mount alternatives we carry are the ABH A460HD heavy duty aluminum continuous gear hinge, half surface, rated to 450 lbs, and the NGP HD5400A half surface geared hinge in aluminum alloy at 83 inches, which carries a 10C 90 minute fire rating on hollow metal. Both mount the same way as the Pemko, so they are direct swaps in a half surface prep.
13) I need a hinge that lets the door swing fully clear of the opening for wheelchair access. Is this the right one?
No. The HS-SF-HD1 is a standard half surface geared hinge, not a swing clear model, so the door leaf still occupies part of the opening at 180 degrees. For clear-width gain on a healthcare corridor look at the ABH A210HD full surface swing clear continuous gear hinge instead.
14) Is there another continuous hinge with the same safety design as the Pemko HS-SF-HD1?
The ABH A135HD is a heavy duty aluminum continuous gear hinge with a safety design, which is the same intent as the Pemko HS-SF-HD1 safety hinge — closing off the hinge-side gap so fingers cannot be pinched. The Pemko is specified half surface with 180 degree maximum swing and 21/32 inch minimum hinge clearance, and it is written for retrofit in child care and nursing facilities. Confirm the mount type of the A135HD against your existing prep before swapping.
15) The door needs to clear an obstruction in the frame reveal — is there an offset alternative to the HS-SF-HD1?
The Design Hardware FSOHD is a full surface offset heavy duty continuous geared hinge, which shifts the pivot point away from the frame face to clear trim or an adjacent wall condition. The Pemko HS-SF-HD1 is a straight half surface hinge giving 180 degrees maximum swing with 21/32 inch minimum hinge clearance, so if the reveal is tight or trimmed, measure that clearance before choosing between them.
16) I need steel or stainless instead of aluminum for a continuous hinge — what is comparable to the Pemko HS-SF-HD1?
The Pemko HS-SF-HD1 is aluminum. If the spec calls for a ferrous or stainless body, the BEST 641 is a steel full mortise continuous hinge and the BEST 651 is stainless steel full mortise, both with hospital tips and both medium duty. Note the mount change — those are full mortise, so the door edge and frame rabbet have to be prepped rather than surface mounting to the door face.
17) Do the finish choices differ by length on the Pemko HS-SF-HD1?
No. Both Clear Anodized Aluminum and Dark Bronze Anodized Aluminum are offered in all four stock lengths, 83, 85, 95 and 120 inches, so you can standardize one finish across a building regardless of door height.
18) Is this hinge suitable for a stainless steel or medium duty opening instead of aluminum?
The HS-SF-HD1 is an aluminum heavy duty hinge. If your spec calls for steel or stainless in a full mortise prep, the BEST 641 steel and BEST 651 stainless steel full mortise continuous hinges with hospital tips are the medium duty options we carry, and the BEST 663HD and 664HD are the heavy duty steel choices with a 90 minute UL fire rating.
