Don-Jo HR120 – Frequently Asked Questions

1) What size is the Don-Jo HR-120 hinge reinforcement plate and will it cover a standard 4-1/2 inch hinge?
The HR-120 measures 10 inches long by 1-1/2 inches wide. At 10 inches it runs well past the 4-1/2 inch height of a standard commercial butt hinge, so it spreads the load above and below the hinge leaf rather than just behind it. The 1-1/2 inch width is the limiting number to check: it covers the frame or door face at the hinge leaf, not a full 4-1/2 inch leaf depth, so measure the flat face you intend to back up before ordering.
2) I have a hollow metal frame where the hinge screws have stripped out. Is this the right fix?
That is what the HR-120 is for. It is a steel hinge reinforcement plate that backs up the hinge mounting area so fasteners have solid material to bite into instead of torn-out hollow metal. Don-Jo also groups it with filler plates, so it does double duty covering a chewed-up or oversized hinge cutout. On a frame with a badly deformed hinge pocket, confirm the damaged area falls inside 10 by 1-1/2 inches, because the plate will not bridge anything larger.
3) How thick is the steel on the Don-Jo HR-120?
Seven gauge, which Don-Jo states as .180 inch. That is heavy plate for a reinforcement, and the practical consequence is that it does not flex when a hinge screw is torqued down or when the door is pulled on. The trade-off is that .180 inch sits proud of the surface unless you mortise for it, so plan on either a surface application or a routed pocket.
4) Does the Don-Jo HR-120 come as a single plate or in a pack?
It ships as a shelf pack of 50 plates. That quantity suits a contractor or facility manager doing a run of openings rather than a one-door repair, so if you are chasing a single stripped hinge you are buying 49 spares.
5) Is the Don-Jo HR-120 a hinge reinforcement or a filler plate? I need to cover an old hinge cutout.
Both uses apply. Don-Jo lists the HR-120 as a hinge reinforcement and files it under filler plates, so the same 10 by 1-1/2 inch plate either backs up a live hinge or blanks off a hinge mortise that is no longer used. For a cover-up job the thing to check is the mortise depth: at .180 inch the plate is thicker than a typical hinge-leaf mortise is deep, so it will stand proud of the frame face unless the pocket is deepened.
6) Can I standardize on the HR-120 across a school or hospital with mixed door types?
The HR-120 is dimensionally fixed at 10 by 1-1/2 inches in 7 gauge steel, and it is sold in one configuration, so there is nothing to spec per opening. That makes it straightforward to stock one part number across a building. The check to run before you standardize is the width: every opening you plan to cover needs at least 1-1/2 inches of flat face at the hinge, and openings with narrower hinge stiles or a different hinge height will want a different size plate.
7) Is the Don-Jo HR-120 meant for commercial doors or will it work on residential?
Don-Jo classifies the HR-120 as a commercial product, and the 7 gauge steel build is aimed at commercial openings where hinge screws pull out under traffic. Nothing stops it going on a residential door, but on a 1-3/8 inch interior door the .180 inch plate is more mass than the opening needs and will read as an obvious surface-applied repair.
