The tool shown in the image is a lightweight manual skeleton frame caulking gun designed for dispensing caulk, silicone, adhesive, and sealant from standard cartridges during sealing, filling, and waterproofing jobs.
Open Steel Cradle: Constructed with a simple, yellow-painted open skeleton frame that holds standard caulk cartridges securely while providing clear visibility of the remaining material.
Smooth Hex Rod & Spring Drive: Features a smooth metallic plunger rod driven by a spring-loaded gripping mechanism for smooth, consistent pressure during squeeze-and-release cycles.
Rear Curved Hook: Designed with a curved metal hook at the back end of the rod, making it easy to pull back manually for cartridge loading and convenient for hanging on ladders or tool belts.
Integrated Seal Punch / Spout Cutter: Built with an attached swing-out wire seal punch tool along the bottom frame to easily puncture internal caulk cartridge seals before use.
