The tool shown in the image is a heavy-duty manual skeleton frame caulking gun designed for dispensing caulk, silicone, adhesives, and sealants from standard cartridges along joints, seams, and gaps.
Reinforced Skeleton Cradle: Built with a sturdy yellow steel open-frame cradle that securely holds standard sealant cartridges while giving clear visibility of the material levels.
Serrated Pressure Rod & Hook: Features a notched ratchet drive rod for incremental, controlled dispensing, ending in a metallic curved hook for pulling back the plunger or hanging the tool on ladders.
Ergonomic Trigger Assembly: Equipped with a yellow cast-alloy pistol grip handle designed for optimal leverage, reducing hand fatigue during high-viscosity material application.
Quick-Release Thumb Lever: Positioned directly behind the trigger housing, the spring-loaded metal thumb release lever instantly disengages the drive rod to stop material flow and prevent mess.
