Pemko CHS83 – Frequently Asked Questions

1) Will the Pemko HS Series continuous hinge work on a 2-inch thick hollow metal door?
Yes. The HS Series half surface geared hinge covers door thicknesses from 1-3/4 inches through 2-1/4 inches, so a 2 inch door is inside the range. Door width is covered up to 4 feet. It is built for hollow metal doors and frames and conforms to SDI specifications for hollow metal frame applications.
2) What is the difference between a half surface continuous hinge and a full mortise one?
A half surface hinge like the Pemko HS applies to the exposed surface of the door and the frame rabbet, so no special hinge reinforcement has to be cut into an existing opening. That is why it is the usual pick for retrofits on hollow metal. A full mortise geared hinge instead sits inside the hinge pocket between door edge and frame rabbet and is cleaner looking on new work where the prep can be done up front. If full mortise is what the opening calls for, the Design Hardware Full Mortise heavy duty geared hinge or the BEST 651 stainless full mortise continuous hinge cover that mounting style.
3) We need a 90 minute fire rated continuous hinge on a hollow metal opening - what are the options alongside the Pemko HS Series?
The Pemko HS Series carries UL 10C fire testing certification and complies with ANSI/BHMA A156.26. Among geared hinges, the BEST 663HD is a heavy duty continuous hinge with a 90 minute UL fire rating for 3/32 inch inset doors, the BEST 664HD is the full surface heavy duty version with a 90 minute UL rating, and the NGP HD5400A half surface hinge is 10C fire rated 90 minutes on hollow metal. Match the mounting style to the opening: the HS Series and the HD5400A are half surface, the 664HD is full surface.
4) What is the closest half surface continuous geared hinge equivalent to the Pemko HS Series?
The NGP HD5400A is the nearest match. Both are half surface continuous geared hinges of aluminum construction, and both are offered in an 83 inch length. The Pemko HS Series is Grade 1 and covers doors 1-3/4 inch to 2-1/4 inch thick, with lengths from 79 inches up to 10 feet and clear anodized or dark bronze anodized finishes. The NGP HD5400A is listed at 83 inches and is 10C fire rated for 90 minutes on hollow metal. If you need a length other than 83 inches on a single order, the Pemko HS covers the wider length range.
5) The frame rabbet is not available for a half surface hinge - what should I use instead of the Pemko HS Series?
Go to a full surface geared hinge, which applies entirely to the face of the door and frame. The Design Hardware FSHD is a full surface heavy duty continuous geared hinge, and the NGP HD5700 is a full surface geared hinge with 1/16 inch door inset sized for 1-3/4 inch to 2-1/4 inch doors, the same door thickness range the Pemko HS Series covers. The BEST 664HD is another full surface geared option, rated heavy duty with a 90 minute UL fire rating.
6) Do I need to order fasteners separately for a Pemko HS continuous hinge?
No, the fastener package comes with the hinge. The frame leaf uses #12-24 x 7/16 inch FHUC Type C threadforming screws. For the door leaf there are two options supplied: 1/4-20 x 1-5/8 inch thru-bolts, or 1/4-20 x 1 inch PCH shoulder bolts. Which you use depends on whether you are going through the door face or into a reinforced door edge.
7) Can a continuous geared hinge fix a sagging door that no longer lines up with the frame?
That is one of the reasons to use the Pemko HS. It runs the full height of the door so the weight is carried along the whole edge instead of three butt hinges, and the half surface mounting allows adjustment to bring the door edge back into alignment with the frame. It swings a full 180 degrees once set.
8) Is a steel pin and barrel continuous hinge a substitute for the Pemko HS Series?
They are different products. The Pemko HS Series is a geared hinge that applies to the door and frame surface and allows adjustment to align the door edge to the frame. 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 version, also medium duty. Those mortise into the hinge edge and require the prep the HS Series avoids, and they are catalogued at medium duty where the HS Series is Grade 1 for heavy weight applications.
9) Which continuous geared hinge should I use on a door with an offset pivot style condition rather than a flush rabbet?
The Design Hardware FSOHD is a full surface offset heavy duty continuous geared hinge, built for openings where the door face is offset from the frame face. The Pemko HS Series is a half surface hinge applied to the exposed door surface and the frame rabbet, and conforms to SDI specifications for hollow metal frame applications, so it suits standard hollow metal rabbeted frames rather than offset conditions.
10) Is the NGP HD1100A an alternative to the Pemko HS Series?
They mount differently. The NGP HD1100A is a concealed continuous geared hinge at 83 inches, listed as Grade 3 and 10C fire rated for 90 minutes on hollow metal, and it conceals within the opening rather than applying to the exposed surfaces. The Pemko HS Series is half surface, Grade 1 aluminum, and applies to the outside of the door and frame rabbet so existing openings need no new hinge reinforcement.
11) Is there a continuous geared hinge with a finger safety design instead of the Pemko HS Series?
The ABH A135HD is a heavy duty aluminum continuous gear hinge with a safety design, which is the option to look at for openings in schools or daycare where hinge edge pinch protection is required. The Pemko HS Series is a standard half surface geared hinge with 180 degree swing, Grade 1 aluminum, for doors 1-3/4 inch to 2-1/4 inch thick.
12) Will a Pemko HS hinge in dark bronze match the other doors in my building?
The HS Series is offered in two anodized aluminum finishes, clear and dark bronze, in every stocked length (83, 85, 95 and 120 inches). Dark bronze anodized is the common match for bronze storefront and dark painted hollow metal; clear anodized reads as a natural aluminum silver.
13) Is a continuous hinge worth it on high traffic doors compared to standard butt hinges?
On openings that cycle constantly, the failure point with butt hinges is the door pulling out at the top hinge and the screws stripping the frame reinforcement. A Pemko HS continuous geared hinge distributes the load over the full height of the leaf, and the Grade 1 aluminum construction is the heavy weight class. It is specified in offices, schools, healthcare, retail, warehouses, multi-tenant residential and municipal buildings for that reason.
