Professional Foam Dispensing Gun
Lightweight. Just 8 Oz!


The FNS300 is our middle of the line insulation foam dispensing gun. It is comparable to pro foam guns like the Great Stuff™ Pro 14, Fomo™ Handi-Tool HT500 and the Touch ‘n Foam™ Sharpshooter-X foam gun applicator. The FNS300 is lightweight and very comfortable to hold for an extended period of foaming operation. It allows precise control for filling, sealing and insulating gaps, cracks and window and door voids. The FNS300 foam insulation gun is equipped with a Teflon® coated needle and foam canister basket to minimize foam from curing on the the basket. It also makes it easier to attach and remove empty foam canister. The reliable FNS300 is reusable up to 30 days.
