NGP HP90-FB – Frequently Asked Questions

1) Can I fill an old flush bolt cavity in a 90-minute fire door without losing the label?
That's exactly what the NGP HP90-FB kit is certified to do. It's application certified for filling manual or automatic flush bolt preparations on fire-rated doors rated up to 90 minutes, on both hollow metal and wood construction, under ANSI/UL 10C and ANSI/UL 10B. So when a pair of doors gets converted and the inactive leaf no longer needs flush bolts, the cavity gets filled with a certified assembly rather than a shop-made patch.
2) Does the HP90-FB filler kit work on wood doors or only hollow metal?
Both. The HP90-FB hardware prep filler is application certified on hollow metal and wood fire-rated doors, so a single kit covers a mixed opening schedule where some leaves are steel and some are mineral-core wood.
3) Is the NGP HP90-FB approved for positive pressure fire door openings?
Positive pressure certified, and stated to meet IBC, NFPA 80 and NFPA 252 requirements for positive pressure fire door applications. It's also certified for use in both the US and Canada.
4) What comes in the NGP HP90-FB flush bolt filler kit?
The kit ships as a complete system: an HP90 2 x 6 inch rectangular fire-rated panel, an HP90 0.5 inch cylindrical fire-rated panel, six powder-coated primer gray steel filler plates, a hardware pack, and GapGuard fire caulk. The steel plates are two edge filler plates (HP90-FBE6750 and HP90-FBE8500), three latch bolt filler plates (HP90-FBL2000, HP90-FBL2500, HP90-FBL3875), and one strike filler plate (HP90-SF2250). That covers the edge prep, the bolt hole and the frame strike side of a flush bolt removal in one order.
5) Can I use the HP90-FB kit when I'm installing new hardware over an existing prep, not just removing hardware?
Both cases are covered. The hardware prep filler is certified for fire doors when removing existing hardware and when installing new hardware over an existing preparation, which is the usual retrofit situation: the new device doesn't land on the old holes and the leftover cavity still has to be closed to keep the door's rating intact.
6) Is the NGP HP90-FB rated for 20-minute or 3-hour fire doors too?
The certification on the HP90-FB tops out at 90 minutes. It's certified on hollow metal and wood fire-rated doors rated up to 90 minutes, which covers the common 20, 45, 60 and 90 minute labels. For a 3-hour opening it isn't the right kit, and on those doors the filler has to carry a matching rating, so specify accordingly.
7) Do I need to buy screws separately to install the HP90 filler plates?
No, the fasteners come with the kit. The hardware pack includes #10-32 x 1-3/4 inch flat head Phillips stainless machine screws, #8 x 3/4 inch flat head Phillips stainless combo screws, #12 x 1 inch flat head Phillips stainless combo screws, and SMS fasteners. The one thing to plan for is finish: the steel plates arrive in powder coated primer gray, so if the filled area has to match the door, budget for paint.
8) Is there more than one version of the NGP HP90 filler kit, and which one handles flush bolts?
The HP90-FB is the flush bolt configuration, and that's the type this kit is built and certified around, manual or automatic flush bolt cavities. The plate mix reflects it, edge fillers plus latch bolt fillers plus a strike filler, which is what a flush bolt removal leaves behind on the door edge and in the frame.
9) Is the HP90-FB filler kit meant for commercial openings or residential doors?
It's a commercial product, and the applications track that: office building fire doors, school exits, healthcare rated openings, industrial fire barriers, multi-tenant residential corridor doors and government buildings. Anywhere a labeled door is in play and hardware is changing.
