This heavy-duty manual skeleton gun is suitable for dispensing mastic and sealant from 310ml and 400ml cartridges. Commonly used on building sites for glazing, frame fitting, and general construction tasks, it helps achieve an even and precise bead for sealing joints and gaps.
The open frame design allows quick cartridge changes and straightforward cartridge visibility during use. With a 7:1 trigger ratio, the tool reduces manual effort and supports steady operation across a range of building maintenance and installation jobs.
