High-quality foam gun for the professional application of commercially available gun/mounting foam (1K-PU foams) in hard-to-reach areas. Features: Controlled filling and insulating thanks to infinitely adjustable output quantity. PTFE coating (gun body, adapter, trigger, application nozzle) prevents foam residue from sticking. High-quality and lightweight gun body and adapter made of aluminum alloy with a metal trigger. Application nozzle made of stainless steel with a copper tip. Ergonomic rubber handle for precise and comfortable operation. Notes: The gun should only be stored in a vertical position with the foam canister screwed on for a maximum of one month after use, as the foam will harden in the nozzle otherwise.
