The Bosch GCG18V-20 gives users smoother, more controlled caulk and adhesive application without the strain of a manual gun. It provides powered dispensing for sealants, caulk, and construction adhesives, including high-viscosity anchor adhesives. Its 18V motor delivers up to 790 lb. of push force and a maximum 21" per minute feed rate.

Nine speed settings and a variable-speed trigger help users control bead size for different materials and applications. The auto-reverse feature pulls the plunger back after the trigger is released to help reduce dripping and material overflow. A 360° rotating barrel helps users apply material in tight or awkward areas while maintaining a comfortable hand position. The tool fits 10 oz. and 13 oz. tubes, as well as 10 oz., 13 oz., and 20 oz. sausage packs, and includes a hanging hook and lockout switch for added jobsite convenience.
