Pemko CHS83HD1 – Frequently Asked Questions

1) Will the Pemko HS Series half surface continuous hinge fit a 2-inch thick door?
Yes. The HS-HD1 half surface geared hinge covers door thicknesses from 1-3/4 inches through 2-1/4 inches, so a 2 inch leaf sits in the middle of the range. It also needs a minimum of 1/8 inch hinge clearance at the gap to swing properly, and the door can be up to 4 feet wide.
2) What is the difference between a half surface continuous hinge and a full mortise or full surface one?
Half surface means the frame leaf mortises into the frame while the door leaf mounts to the face of the door. That is why the Pemko HS Series is aimed at retrofit work: you can reuse an existing hollow metal frame prep without machining the door edge. A full mortise hinge like the Design Hardware FMHD or the ABH A120HD mortises into both the door edge and the frame rabbet, which is the cleaner look on new openings but means prepping both. Full surface, such as the Design Hardware FSHD or BEST 664HD, screws to the face of both door and frame, which is the choice on doors you cannot machine at all.
3) What length Pemko HS Series hinge do I order for a 7-foot door, and can I get one for a 10-foot opening?
Stock lengths are 83, 85, 95 and 120 inches. A standard 7 foot (84 inch) door takes the 83 inch hinge, which is the shortest the HS-HD1 is made in. Tall openings are covered by the 95 and 120 inch sizes, and 10 feet is the maximum length the series is built to. Custom lengths are made for project specific heights.
4) Does the Pemko HS-HD1 continuous hinge work on a wood frame or an aluminum storefront?
No. The HS Series half surface hinge is built for hollow metal frames where the insert conforms to SDI specifications, and the frame leaf fastens with #12-24 x 7/16 inch FHUC Type C threadforming screws, which are metal threadforming fasteners. Threadforming screws will not hold in wood, and this is not a storefront hinge. If your frame is not hollow metal, you need a different mounting style.
5) Is the Pemko HS Series continuous hinge Grade 1 and does it meet A156.26?
Grade 1, and compliant with ANSI/BHMA Standard A156.26, the standard that covers continuous hinges. It also carries UL 10C fire test certification. Those are the three lines a spec writer or a facilities buyer standardizing across a building normally needs to see on a continuous hinge submittal.
6) Will a continuous geared hinge stop my commercial door from sagging where the butt hinges keep failing?
That is the usual reason to switch. The HS-HD1 runs the full height of the door and carries the load along the entire edge instead of at three or four points, at 1.28 lbs per foot of aluminum. It also has adjustable alignment built in, so the door edge can be brought back parallel to the frame during install rather than shimming a butt. On a high traffic opening in a school, hospital or retail entry this is the fix for a door that has torn out its hinge screws.
7) What is the closest half surface continuous geared hinge to the Pemko HS-HD1 from another manufacturer?
The ABH A460HD is the nearest half surface aluminum continuous gear hinge equivalent, rated at 450 lbs capacity. The NGP HD5400A is also a half surface continuous geared hinge in aluminum alloy, offered at 83 inches and fire rated 90 minute under UL 10C on hollow metal. The Pemko HS-HD1 is a Grade 1 aluminum half surface geared hinge covering 1-3/4 inch to 2-1/4 inch doors in lengths from 79 inches to 10 feet. All three mount the same way: the door leaf sits on the face of the door and the frame leaf goes into the frame rabbet, so all three suit retrofit work where the door edge is not being machined.
8) What continuous hinge should I use if the door edge can be machined instead of surface mounting?
A full mortise geared hinge is the choice when the door and frame can be prepped. The ABH A120HD is a heavy duty aluminum full mortise continuous gear hinge with Easy Install Technology, and the Design Hardware FMHD is a heavy duty full mortise continuous geared hinge. The BEST 663HD is a heavy duty continuous hinge for 3/32 inch inset doors with a 90 minute UL fire rating. The Pemko HS-HD1 is half surface, so it fastens to the door face and needs no edge machining, which is why it is specified for retrofit into existing hollow metal frames.
9) I need a continuous hinge on a 90 minute fire rated hollow metal opening - what are my options?
The NGP HD5400A half surface hinge, the NGP HD5700 full surface hinge, and the NGP HD1100A concealed hinge are all 10C fire rated 90 minute on hollow metal. The BEST 663HD and BEST 664HD are heavy duty continuous hinges with a 90 minute UL fire rating. The Pemko HS-HD1 carries UL 10C fire test certification and is Grade 1 aluminum built for hollow metal frames with an SDI conforming insert. Confirm the length and door weight against the opening before ordering, since fire rated listings are length dependent.
10) Can a door on a Pemko HS Series hinge swing back a full 180 degrees against the wall?
Yes, 180 degrees is the maximum swing on the HS Series half surface hinge, provided nothing in the opening blocks it and you have the 1/8 inch minimum hinge clearance. That matters where a door has to stand flat for gurney or cart traffic. If you need the door to clear the full width of the opening for ADA clearance, that is a swing clear hinge instead, such as the ABH A210HD full surface swing clear.
11) What screws come with the Pemko HS-HD1 hinge and do I need to thru-bolt the door leaf?
The frame side uses #12-24 x 7/16 inch FHUC Type C threadforming fasteners. On the door side you choose between thru-bolts and self-drilling screws. Thru-bolts are the call on a hollow metal door in an abuse-prone opening where screws can pull out of the face sheet; self-drilling screws are quicker and adequate on a lighter duty install. Specify which you want when you order.
12) I do not want the hinge visible when the door is closed. Is there a concealed continuous hinge instead?
The Pemko HS Series is a half surface hinge, so the door leaf is on the face of the door and stays visible. For a hinge that is hidden with the door shut, look at the NGP HD1100A, an 83 inch concealed continuous geared hinge that is 10C fire rated 90 minutes on hollow metal. Note it is a Grade 3 hinge, not Grade 1 like the HS-HD1, so on a high cycle opening the trade-off for the concealed look is duty level.
13) Is the NGP HD1100A a substitute for the Pemko HS-HD1?
They are different mounting types. The NGP HD1100A is a concealed continuous geared hinge at 83 inches, listed as Grade 3 and 10C fire rated 90 minute on hollow metal, and a concealed hinge sits within the door and frame so nothing shows when the door is closed. The Pemko HS-HD1 is a half surface hinge carrying a Grade 1 rating, with the leaf exposed on the door face. If the specification calls for Grade 1 or for a surface applied retrofit, the HD1100A does not stand in for it.
14) Is there a lighter duty continuous hinge than the Pemko HS-HD1 for an interior office door?
The BEST 641 is a steel full mortise continuous hinge with hospital tips at a medium duty level, and the BEST 651 is the stainless steel full mortise version, also medium duty. Both are full mortise, so the door edge and frame rabbet have to be prepped. The Pemko HS-HD1 is heavy duty Grade 1 aluminum sized for doors up to 4 feet wide at 1.28 lbs per foot, and it mounts half surface without machining the door edge.
15) What continuous hinge is used where the frame is offset or the door has to clear a projecting frame?
The Design Hardware FSOHD is a full surface offset heavy duty continuous geared hinge, built for openings where the door leaf has to stand off from the frame face. The Pemko HS-HD1 is a straight half surface hinge with adjustable alignment for setting the door edge to the frame, so it is intended for a conventional hollow metal frame rather than an offset condition.
16) Which continuous geared hinge has a safety design to protect fingers at the hinge edge?
The ABH A135HD is a heavy duty aluminum continuous gear hinge with a safety design, which is the one to look at for schools, daycare, and healthcare corridors where pinch protection at the hinge side is a requirement. The Pemko HS-HD1 is a heavy duty half surface geared hinge with a 180 degree maximum swing and does not carry a safety edge feature.
17) What finishes does the Pemko HS Series heavy duty continuous hinge come in?
Two anodized aluminum finishes, clear and dark bronze, and both are offered in every stock length (83, 85, 95 and 120 inches). Clear anodized is the standard match for aluminum frames and most commercial openings; dark bronze is what you order to blend with bronze storefront or dark painted hollow metal.
