NGP HS-1 – Frequently Asked Questions

1) Can I use a hinge shim on a fire-rated door without voiding the rating?
The NGP HS-1 steel hinge shim is certified for use on UL fire doors rated up to 90 minutes, tested to CAN/ULC-S104, ANSI/UL10B and ANSI/UL10C, and it meets NFPA 80 and NFPA 252 requirements. That covers both hollow metal and wood fire doors in the US and Canada. The ANSI/UL10C listing is the positive pressure test, which is what an inspector looks for under IBC.
2) Will a 42 inch hinge shim work on standard 4-1/2 inch butt hinges, or is it only for continuous hinges?
Both. The HS-1 ships as one 42 inch strip for a continuous hinge, and it is scored into 3-1/2 inch break-off sections so you can snap off a piece for a standard butt hinge leaf. One part covers the geared continuous hinge on a stairwell door and the three butt hinges down the hall.
3) How do I close up an excessive hinge-side gap on a fire door that keeps failing inspection?
Shimming behind the hinge leaf is the fix, and that is what the HS-1 does. Steel shim stock goes between the leaf and the mortise to push the door away from the hinge jamb and take up clearance at the strike side. It is stackable, so if one thickness does not bring the gap into range you add another. Because the shim is UL certified to ANSI/UL10B and ANSI/UL10C, adding it does not compromise the door's label.
4) Do hinge shims stay in place while you hang the door, or do they fall out?
Pressure sensitive adhesive pads come on the HS-1, so the shim sticks to the jamb or the hinge leaf while you set the door and drive the screws. The adhesive is removable and re-stickable, so if you overshoot the clearance you can peel it and reposition rather than starting with a fresh piece.
5) Is the NGP HS-1 hinge shim steel or plastic?
Steel. That matters on a fire door: the shim sits in the hinge pocket where it sees the door's full weight through the leaf, and it has to survive the same furnace test the door does. The HS-1's certification to CAN/ULC-S104, ANSI/UL10B and ANSI/UL10C is tied to that steel construction.
6) Is the NGP HS-1 hinge shim approved for use in Canada as well as the US?
Yes on both sides of the border. The shim carries CAN/ULC-S104 for Canada alongside ANSI/UL10B and ANSI/UL10C for the US, and it is certified for hollow metal and wood fire doors in both countries. Useful if you are standardizing one part across a portfolio that spans the two.
7) How many hinge shims come in a box of NGP HS-1?
Ten shims per box, each a 42 inch strip. Since every strip breaks into 3-1/2 inch sections, a single box goes a long way on a butt-hinge punch list, which is how most property managers and MRO buyers end up using it across a floor of openings.
8) Is this hinge shim meant for commercial openings or residential doors?
Commercial. The HS-1 is built for labeled openings in schools, hospitals, hotels, government buildings and multi-tenant residential, where the hinge-side clearance has to be brought into NFPA 80 range without losing the door's fire rating.
