NGP 9990-48IN – Frequently Asked Questions

1) My fire door has a gap at the top bigger than code allows. Can the NGP 9990 fix it without replacing the door?
That's exactly what the 9990 is for. It's a UL certified intumescent door top solution for fire door top gaps measuring up to 1/2 inch, so an existing opening that has drifted out of clearance tolerance can be brought back into compliance without hanging a new door. It mounts on the top of the door as a flat plate with an intumescent cap, and under fire conditions the intumescent expands to close the gap. Certified for use on UL10B and UL10C wood or hollow metal fire doors carrying 90-minute ratings. If your top gap exceeds 1/2 inch, this is not the fix.
2) Will the NGP 9990 gap solution work on a 90-minute wood fire door, or is it hollow metal only?
Both. The 9990 is certified for use on UL10B and UL10C wood or hollow metal fire doors with 90-minute ratings. The door itself has to be a 90-minute rated assembly, that's the limit on where it can go.
3) Do I have to relocate the closer or top hardware to install the NGP 9990?
No. The 9990 is built so there's no need to move hardware at the top of the door, and it works with doors equipped with parallel arm closers. That's the difference between a 20 minute retrofit and pulling and re-prepping a closer on every opening in a corridor.
4) Is the NGP 9990 approved for positive pressure fire test requirements?
Yes, it's UL certified to ANSI/UL10C for positive pressure applications, and it complies with IBC, NFPA 80, and NFPA 252. It's certified for use in both the US and Canada. That covers the inspection questions an AHJ raises on a healthcare or education corridor where the fire door survey has flagged excessive top clearance.
5) Can I use the NGP 9990 to fix an oversized gap at the bottom of a fire door?
No. The 9990 is a door top solution, it mounts on the top edge of the door to close excessive head clearance. Undercut and bottom gap problems on a fire door need a different part, typically an intumescent or fire rated door bottom. Ordering this one for a bottom gap gets you a part that doesn't apply to the condition you're trying to correct.
6) Do I need to specify handing for the NGP 9990 door top gap solution?
No handing to specify. The 9990 is non-handed, so one part covers left and right hand openings, which matters if you are standardizing across a building and don't want two SKUs on the shelf. You do pick a length: 36 inch and 48 inch.
7) What comes in the box with the NGP 9990, and do I need to order fasteners separately?
Fasteners are included. The kit ships with the #304 brushed stainless steel flat plate, the intumescent cap, end caps, and #6 x 3/4 inch stainless steel sheet metal screws. End caps are furnished standard rather than being an add-on line. You supply nothing but a drill and a driver.
8) What is the NGP 9990 made of, and will it hold up in a high-traffic or humid building?
#304 brushed stainless steel for the flat plate, intumescent cap, and end caps, with stainless steel fasteners. 304 is the corrosion-resistant grade, so it suits humid or wash-down adjacent corridors as well as dry office openings. The finish is brushed steel, so it reads as a match against most stainless door hardware already on a commercial opening.
9) Is the NGP 9990 gap solution rated for residential use or commercial only?
Commercial. It's specified for commercial fire-rated openings, offices, schools, healthcare, industrial compartmentalization, government buildings, and multi-tenant residential properties, which are commercial construction even though people live in them. If you manage an apartment or condo building with rated corridor and stair doors, that's squarely the application.
