Ives 112HD Full Mortise Geared Continuous Hinge for 48" Doors up to 450 lbs

Heavy-Duty Continuous Hinge Solution for Commercial Applications

The Ives 112HD Full Mortise Geared Continuous Hinge is engineered for 1-3/4" doors with a maximum width of 48" and supports door weights up to 450 pounds without reinforcing or 600 pounds with reinforcing. This ANSI 156.26 Grade 1 certified hinge features a spread bearing design with transmission gear technology and bearings spaced every 3" on center for smooth, reliable operation. The full mortise design mounts on the side of the door stile and inside of the frame side jamb with only the gear cover visible when the door is closed.

Ives 112HD-83-US28 – Frequently Asked Questions

1) Do I have to order a left hand and a right hand version of the Ives 112HD?
No. The 112HD is non-handed, so one part number covers left hand and right hand openings. That is one of the practical reasons facilities standardize on continuous geared hinges: you stock a length and a finish, not a handing matrix.
2) How do I order an Ives 112HD for a door with an electric lock or card reader?
Specify the EPT option. Every length of the 112HD is offered with an electrical power transfer prep, for example 112HD-83-313AN EPT or 112HD-95-313AN EPT, which routes wiring from the frame into the door through the hinge instead of a separate door loop or transfer hinge. If the opening has no electrified hardware, the standard version is the one to order.
3) Full mortise or full surface continuous hinge, which one do I need?
Full mortise, which is what the 112HD is, mounts into the edge of the door stile and the inside of the frame jamb, so only the gear cover shows when the door is closed. It requires the door and frame to be prepped and routed for it, so it suits new work or a door you can pull and machine. A full surface hinge instead screws onto the face of the door and frame with no routing, which is the choice when you cannot take the opening apart or the existing frame will not accept a mortise prep.
4) Will the Ives 112HD fit a beveled edge door?
Both beveled and square edge doors are covered by the 112HD. That matters on retrofits, where a heavy commercial leaf hung on butts is often beveled on the hinge edge and a hinge that only takes square edge doors would force a door replacement.
5) Will a continuous geared hinge stop my heavy door from sagging?
That is the main reason to move off butt hinges. The 112HD runs the full height of the opening and spreads the door weight along the entire frame length instead of concentrating it at two or three hinge points, which is where sag and dragging start on a heavy leaf. Bearings sit every 3 inches on center, and the spread bearing transmission gear design keeps the door in alignment through its life rather than needing periodic reshimming.
6) What screws does the Ives 112HD install with, and do I need anything else?
It mounts with 12-24 x 3/4 inch steel self-drilling, self-tapping Phillips head screws, with security fasteners available as an option for high abuse or detention-adjacent openings. Ives supplies templates for marking the hole locations on the door stile and the frame jamb interior. If the door is over 450 lbs, the frame needs reinforcing to reach the 600 lb capacity, so plan that before the door goes back up.
7) What finishes does the Ives 112HD come in?
Two anodized aluminum finishes: 628 clear anodized and 710 dark bronze anodized. Both are available in all four lengths (83, 85, 95 and 120 inches) and in both standard and EPT versions, so you can match the rest of the aluminum storefront or door line without changing hinge length or prep.
8) Is a continuous hinge safer than butt hinges for a school or daycare door?
It removes the pinch gaps. Butt hinges leave open spacing between each leaf on the hinge side, and that gap is where fingers get caught. The 112HD is one continuous piece down the full height of the door, so there is no spacing between hinges to pinch, which is why these get specified on educational and healthcare openings.
