The Makita 12V CXT™ Lithium-Ion Cordless 10 oz. Caulk and Adhesive Gun (model GC01ZA) is a versatile, powerful and lightweight solution for dispensing large amounts of caulk and adhesives. The GC01ZA delivers a full 1,100 lbs. of dispensing force for the highest viscosity adhesives and sealants. It features a 5-speed dial (0-66 IPM) and variable speed trigger that optimizes flow rate. The 360-degree rotatable cartridge holder fits 10 oz. and 300 ml cartridges. Added features include an overload-indicator light to minimize breakage of sealant cartridges, L.E.D. light, and drip-reduction feature that automatically relieves pressure on the material when the trigger is released to prevent unintentional dispensing. For longer run time, 12V max CXT™ cordless tools are also compatible with the 12V max CXT™ Lithium-Ion 4.0Ah battery (BL1041B, sold separately). 12V max CXT™ Lithium-Ion batteries are engineered with a Battery Protection Circuit that protects against overloading, over-discharging and over-heating. It’s part of the expanding 12V max CXT™ series, combining performance with superior ergonomics in a compact size.
