Design Hardware Full Mortise - Heavy Duty Continuous Geared Hinges

No handing to specify. These ship non-handed, so one part number covers both a left and a right opening, which is the reason a lot of property managers stock a single length across a building. Handing only enters the picture if the hinge gets cut down on site.

Full mortise mounts into the edge of the door and the rabbet of the frame, so the hinge is concealed when the door is closed. That takes a prepped opening. Full surface bolts to the face of the door and the face of the frame instead, which is what you use on a retrofit where the existing edge and frame prep is chewed up or where you can't machine the door. Design Hardware builds this geared line in both types. For a face-applied job from other brands ZenSupply stocks, the BEST 664HD is a heavy duty full surface geared hinge and the ABH A210HD is a full surface swing clear.

That is the case for one. A continuous geared hinge carries the door load along the entire height of the leaf rather than at three points, and this Design Hardware unit runs 32 self lubricating concealed bearings per hinge. Butt hinges concentrate the load at the top hinge, which is why sagging doors and torn frame screws show up on entrances, restrooms and stairwells. Rated Heavy Duty and built for commercial openings.

The Design Hardware Full Mortise Heavy Duty continuous geared hinge is a heavy duty aluminum full mortise hinge in 83 inch and 95 inch stock lengths. The closest cross-brand match in full mortise geared form is the Pemko FM-RG Series, a Grade 1 aluminum full mortise raised geared continuous hinge with 180 degree swing. The ABH A120HD is also a full mortise heavy duty aluminum continuous gear hinge, built with ABH Easy Install Technology. Both are aluminum full mortise geared hinges like the Design Hardware unit; the Pemko is a raised gear profile while the Design Hardware hinge uses 32 self lubricating concealed bearings per hinge.

For a fire rated opening, the NGP HD1100A is a concealed continuous geared hinge in 83 inch length carrying a 10C fire rating for 90 minutes on hollow metal. 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 version of that hinge with the same 90 minute UL fire rating. The NGP HD5400A half surface and NGP HD5700 full surface geared hinges also carry the 10C 90 minute rating on hollow metal, so the choice among them comes down to whether the opening takes a mortise, half surface, or full surface leaf.

The Design Hardware heavy duty continuous geared hinge is made in Full Mortise and Full Surface types. If the opening needs a surface applied hinge from another brand, the BEST 664HD is a heavy duty full surface continuous geared hinge, and the NGP HD5700 is a full surface geared hinge cut for 1/16 inch door inset on 1-3/4 inch to 2-1/4 inch doors. For a half surface leaf, the ABH A460HD is a heavy duty aluminum continuous gear hinge rated to 450 lbs capacity and the NGP HD5400A is an 83 inch half surface geared hinge in aluminum alloy.

No. The Design Hardware Full Mortise continuous geared hinge is a heavy duty hinge with 32 self lubricating concealed bearings per hinge for heavy duty applications. 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. They share the full mortise mounting, so they look interchangeable in a takeoff, but they sit at a different duty level than the Design Hardware unit. Within the heavy duty full mortise group, the ABH A120HD and Pemko FM-RG Series are the closer matches.

The Design Hardware Full Mortise heavy duty continuous geared hinge is built to ANSI A156.2 and ANSI A156.7. Among the cross-brand options, the Pemko FM-RG Series, Pemko FM-SLF, Pemko CFM84SLF-HD1 and Pemko DSH1000 are all listed at Grade 1. The NGP HD1100A concealed geared hinge is a Grade 3 hinge, so it is the one to check carefully against a Grade 1 submittal even though it carries the 10C 90 minute fire rating on hollow metal.

It's built to ANSI A156.2 and ANSI A156.7. A156.7 is the standard covering template hinge dimensions and A156.2 covers bored and preassembled locks; both appear on the spec for this hinge. The hole patterns are templated, so the prep matches the drawing rather than being laid out on site.

The body is 6063 T6 aluminum alloy, which does not rust the way a plain steel hinge does, and the bearings are self lubricating so there's no oiling schedule. Finishes are 626 satin chrome and 613 satin bronze oil rubbed. If you specifically want stainless on the opening, the BEST 651 is a stainless steel full mortise continuous hinge ZenSupply carries.

Within full mortise, the ABH A120HD is a heavy duty aluminum geared hinge with the brand's easy install technology, the Pemko FM-RG is a Grade 1 aluminum full mortise raised geared hinge with 180 degree swing, and the Pemko CFM84SLF-HD1 is an 84 inch short leaf flush Grade 1 unit. The Design Hardware version is 6063 T6 aluminum with 32 bearings per hinge in 83 and 95 inch. Pick on length first, since 84 inch and 83 inch are not interchangeable on a cut-to-fit opening.

Often, yes. Heavy duty geared hinges earn their keep on entrances, stairwells and anywhere a closer is slamming the door hundreds of times a day. For a lower traffic interior leaf, a medium duty continuous hinge such as the BEST 641 steel full mortise or the BEST 651 stainless, both with hospital tips, does the job. Step up to heavy duty when the door is oversized, has a closer, or is on a main circulation path.

Yes, these are cut in the field, and that's normally how an odd height leaf gets covered. One consequence to plan for: as supplied the hinge is non-handed, and once it's cut it is handed, so you cannot swap a cut hinge onto the opposite swing opening later. Cut on the correct end for the swing you're hanging.

For a 1-3/8 inch door, the Pemko FM-SLF short leaf flush continuous geared hinge is built specifically for 1-3/8 inch doors with Grade 1 construction. The Pemko CFM84SLF-HD1 is an 84 inch full mortise short leaf flush hinge in heavy duty Grade 1 form if a longer leaf is needed. The Design Hardware Full Mortise heavy duty geared hinge is supplied in 83 inch and 95 inch stock lengths with templated hole patterns.

The ABH A135HD is a heavy duty aluminum continuous gear hinge with a safety design at the hinge edge, which is the one to look at for openings where finger protection at the pivot side is the deciding factor. The Design Hardware Full Mortise heavy duty geared hinge is a standard full mortise commercial hinge with 32 self lubricating concealed bearings and a non-handed body unless cut in the field.

The Design Hardware Full Mortise heavy duty continuous geared hinge is built from 6063 T6 aluminum alloy. If the specification names a steel hinge, the BEST 641 is a steel full mortise continuous hinge with hospital tips, and the BEST 651 is the stainless steel full mortise equivalent with hospital tips; both are medium duty. Among the aluminum geared hinges, the NGP HD5400A is aluminum alloy construction and the ABH A460HD, A120HD, A135HD and A210HD are all aluminum continuous gear hinges.

The ABH A120HD is a full mortise heavy duty aluminum continuous gear hinge built around ABH Easy Install Technology, which is the differentiator to look at for repeat installs. The Design Hardware Full Mortise heavy duty geared hinge uses templated hole patterns and is non-handed unless cut in the field, so one part number covers both left and right hand openings across a fleet of doors, in 83 inch and 95 inch stock lengths and 626 satin chrome or 613 satin bronze oil-rubbed finish.
