The 931 One Hand Caulking Gun is innovatively designed with a front-positioned grip that enables true one-handed operation — freeing the other hand to hold materials or steady the workpiece. Its ergonomic contoured handle ensures a comfortable, non-slip grip during extended dispensing tasks. 

With a pressing force of up to 135 kg, it provides consistent, controlled flow of standard sealants and adhesives, and is compatible with standard 310ml cartridges for home sealing and renovation tasks.

Built with strong engineering-grade plastics and a zinc-plated reinforced steel push rod, it delivers reliable strength and durability for daily professional use. All plastic components comply with RoHS and REACH regulations, making it an environmentally responsible and export-ready choice for tradesmen who value efficiency and convenience.
