NGP HD1100A-83 – Frequently Asked Questions

1) Will an 83 inch continuous hinge work on a standard 7 foot commercial door?
The NGP HD1100A is furnished at 83 inches, which is the usual length run on a nominal 7'0" (84 inch) door leaf, leaving the hinge slightly short of the full leaf height so it clears the head and floor conditions. It is a continuous concealed geared hinge, so it runs the full hinge edge rather than seating in three or four butt pockets. If your leaf is 8'0" or an odd height, this length is not the one to order.
2) What is the difference between a concealed continuous hinge and a full surface or full mortise one?
Concealed means the hinge sits between the leaf and the frame and is not visible when the door is closed, with no exposed pin to attack and nothing protruding into the opening. Full surface hinges, like the Design Hardware FSHD or the ABH A460HD half surface, mount on the face of the door and frame instead, which is what you want when you can't or don't want to mortise, or on a retrofit where the existing edge is damaged. Full mortise types such as the Pemko FM-RG Series get let into the edge and frame rabbet. Pick concealed when appearance and security at the hinge edge matter and the opening can be prepped for it.
3) What is the closest full mortise equivalent to the NGP HD1100A concealed continuous geared hinge?
The HD1100A is a continuous concealed geared hinge, so the nearest full mortise geared alternatives are the Pemko CFM84SLF-HD1, an 84 inch full mortise continuous hinge with a short leaf flush profile rated Grade 1, and the Design Hardware FMHD full mortise heavy duty continuous geared hinge. Both mortise into the door and frame edge the way a concealed hinge does, rather than mounting on the face of the opening. The ABH A120HD is a further full mortise heavy duty aluminum geared option with Easy Install technology.
4) What continuous hinge should I use on a 90 minute fire rated opening besides the NGP HD1100A?
The NGP HD1100A carries a 10C fire rating for 90 minutes on hollow metal. Among geared alternatives, the BEST 663HD is a heavy duty continuous hinge with a 90 minute UL fire rating built for 3/32 inch inset doors, and the BEST 664HD is the full surface heavy duty geared hinge with a 90 minute UL fire rating. Choose between them by how the opening is prepped: 663HD suits an inset door condition, 664HD mounts on the face.
5) Do I need to reinforce the door for a continuous geared hinge like the HD1100A?
No hinge reinforcement is needed in the normal case. NGP calls for reinforcement only on extremely heavy, high frequency, or extra wide leaves. That is one of the practical reasons continuous hinges get specified on retrofit work: the load spreads along the entire edge instead of loading three butt pockets, so a tired frame or a sagging leaf usually does not need welding or new prep to accept it.
6) What else could I use instead of the NGP HD1100A on a heavy commercial opening?
Staying in aluminum geared continuous hinges, the Design Hardware FMHD is the full mortise heavy duty option and the ABH A120HD is a heavy duty full mortise aluminum gear hinge. If you need another 90 minute UL fire rated continuous hinge, the BEST 664HD is a heavy duty full surface geared hinge with that rating, and the BEST 663HD is the heavy duty version for 3/32 inch inset doors. Those are different mount types, so the deciding factor is how the existing door and frame are prepped, not the hinge itself.
7) Does the NGP HD1100A hinge need lubrication or scheduled maintenance?
No. The bearings are Teflon infused and self lubricating, so there is nothing to grease on a PM route. For a property manager or facility crew running a lot of high traffic openings, that is the practical argument for a geared continuous hinge over butts: no pin wear, no squeak calls, and the load carried along the whole edge instead of at three points.
8) Is there a lighter duty continuous hinge to use where a heavy duty geared hinge is more than the opening needs?
The BEST 641 is a steel full mortise standard duty continuous hinge with hospital tips, rated medium duty, and the BEST 651 is the stainless steel full mortise continuous hinge with hospital tips, also rated medium duty. Both are pin and barrel style hinges with hospital tips rather than aluminum geared assemblies like the NGP HD1100A, so the leaf profile and the door prep differ from a concealed geared hinge.
9) What continuous geared hinge is made for a 1-3/8 inch door rather than a standard commercial thickness door?
The Pemko FM-SLF short leaf flush continuous geared hinge is built for 1-3/8 inch doors and is Grade 1. The short leaf flush geometry is what makes it suit the thinner door; a standard leaf geared hinge such as the Pemko FM-RG raised geared full mortise hinge, also Grade 1, is aimed at a full swing application with 180 degree operation instead.
10) Will the Pemko DSH1000 work as a substitute for a standard concealed continuous geared hinge?
Not as a like for like swap. The Pemko DSH1000 is an anti-barricade continuous hinge with 100 degree bidirectional operation and is Grade 1, so the door swings both directions to prevent an occupant from blocking the opening. That behavior is specified for behavioral health and detention type rooms. The NGP HD1100A is a continuous concealed geared hinge for conventional single direction commercial openings, so the two are not interchangeable even though both are continuous hinges.
11) What finish and material does the NGP HD1100A continuous hinge come in?
Aluminum alloy 6063-T6 with an anodized aluminum finish, and that is the only finish it ships in. The anodized aluminum reads as a clean silver edge and holds up against corrosion, which is why it gets used on exterior and high humidity openings. If your job specs a painted or bronze hinge edge to match existing hardware, this is not a match.
12) Is the NGP HD1100A meant for commercial openings or will it work in a house?
This is a commercial hinge. It is built for office buildings, schools, hospitals, retail, warehouses, multi tenant residential, and government facilities, on doors up to 600 pounds. On a light residential interior door the capacity and the mortise prep required are far beyond what the opening needs.
13) Which continuous gear hinge is intended for an opening where finger safety at the hinge edge matters?
The ABH A135HD is a heavy duty aluminum continuous gear hinge with a safety design, which addresses the hinge edge condition in schools, healthcare and other high traffic occupancies. The NGP HD1100A is a concealed continuous geared hinge whose leaves are hidden in the door edge when closed. Both are aluminum geared continuous hinges, but only the A135HD is described as a safety design.
