Manufactured by Cooper Industries (the same company that makes DOTCO and Cleco air tools), our CaulkMaster® Sealant Gun works with any industry standard 6oz SEMKIT® style sealant cartridge.

6 oz Retainer fits on our model PG102060 Sealant Gun. (NOTE: This 6oz retainer will ONLY work with CaulkMaster brand Sealant Guns, it will NOT work with the more common Semco 250 Series Sealant Guns.)

Note the CaulkMaster Sealant Gun line has been discontinued by the manufacturer. Once we sell these remaining 6oz Retainers, we will not be able to get any more.
