Built specifically for demanding commercial environments and heavy home DIY use, this professional-grade Caulking Gun accommodates both standard 310ml DIY tubes and larger 400ml trade cartridges. It features a precision-engineered steel skeleton frame, providing maximum rigidity under high pressure without adding unnecessary weight to your tool belt.

• Industrial Build Quality - Uses reinforced steel alloys to prevent frame twisting or flexing.
• Dual-Capacity Carriage - Effortlessly locks in 310ml and 400ml cartridges for seamless swaps between sealants, silicone's, and grab adhesives.
• High-Leverage Thrust Drive - The advanced manual trigger mechanism reduces the hand grip force needed, allowing you to pump dense mastic's or thick construction glues easily.
• Instant Pressure Relief - Features a swift thumb-release clip that backs off the plunger instantly. This prevents messy run-on drips and keeps your work surfaces pristine.
• Jobsite Conveniences - Includes a large U-shaped ladder hook for safe hanging between tasks, plus a protective powder-coated finish to resist.
