The FNS850 XL is identical to the FNS800 except it has a longer barrel for maximum reach in difficult to reach foaming applications. It is also ideal for sub-flooring adhesive application. The 45-inch long gun minimizes back pains as foam can be applied while standing upright. Like all our guns, the FNS850 dispenses consistent foam on every job. The stainless steel foam can adaptor is Teflon coated for greater non-stick and reliable performance. This gun is reusable up to 30 days. The FNS850 is a great alternative to the GREAT STUFF® PRO 14 XL. THE FNS850 offers similar features as the GREAT STUFF PRO XL, but at a greater value. ? Stainless steel needle and check valve ?
