Maxisil Silicone Nozzle Unblocker

Reusable nozzle unblocker for silicone and caulking cartridges. When cured sealant clogs the nozzle tip, drive the screw into the hardened plug and pull it out so the cartridge can be used again. Simple pocket-size tool that suits Maxisil and other standard cartridges and saves throwing away part-used tubes on the job.
