45" XL Extra Long Barrel


The FNS850 shares the same gun body with the FNS800, but the gun barrel length is 45 inch long for the FNS850 and 30 inch long for the FNS800. The FNS850 extended long barrel foam gun is designed for applications that are difficult to reach. The 45-inch gun is also suited for dispensing foam adhesive for sub-flooring installation. The extended barrel  minimizes back pain as the user can apply the adhesive foam standing up. The stainless steel foam canister adaptor basket is Teflon coated to reduce  foam built up resulting in a cleaner foam gun and making it easier to attach and remove foam canisters.

The FNS850 is a cheaper substitute to the Dow Great Stuff Pro 14XL Long Barrel foam gun, Todol Pageris GU24, Touch ‘n Seal Sharpshooter Long Barrel gun foam applicator, and the Tytan Pro Long Barrel foam applicator.
