The Bosch GCG18V-29N 18V Caulk & Adhesive Gun provides powered caulking to reduce the fatigue on your hand from manual caulk and adhesive guns. It has speed selection and a variable-speed trigger for a consistent bead size and easier caulk application. The caulk and adhesive gun features an auto-reverse feature on the plunger rod to help prevent dripping and material overflow. It holds 29 oz. tubes and delivers a no-load max of 18" per minute feed and 790 lbs. of push force, to push even high-viscosity adhesives including anchor adhesives in concrete. The cage rotates, so that material can be applied in difficult areas while still keeping your preferred hand location. And it’s light – only 5 lbs. (tool only, not including battery). Compatible with Bosch 18V LITHIUM-ION batteries, and fits 29 oz. tubes. The caulk and adhesive gun has a hook for hanging between jobs and a lockout switch, so the trigger won’t be accidentally activated. Bare Tool, battery and charger sold separately.
