The STARTUL Master caulking gun with a closed barrel is designed for clean and convenient application of sealants and adhesives. The barrel fully encloses the 310 ml cartridge, protecting it from damage and keeping the workspace tidy. Its aluminum body and smooth thrust mechanism ensure reliable, controlled dispensing.

Key Features:

• Protected & Clean Operation: The closed barrel design shields the cartridge from punctures and prevents accidental leakage, keeping hands and the work area clean.

• Sturdy & Reliable: Constructed from durable aluminum with a reinforced thrust mechanism for steady, consistent material flow.

• Comfortable & Controlled Use: Ergonomic design and an 8 mm thrust rod allow for precise, drip-free application of standard 310 ml sealant tubes.
