The OX Pro 400mL Heavy-Duty Caulk Gun with dual thrust ratios (25:1 / 12:1) is designed to provide versatility, precision, and power for all your sealing needs. The 25:1 thrust ratio is ideal for high-viscosity sealants and adhesives, offering optimal force for controlled, smooth application, while the 12:1 thrust ratio is perfect for lighter caulks, offering greater ease of use for less demanding materials. This allows you to switch between the two settings for different tasks without the need for multiple tools. Featuring a dripless on/off switch, the caulk gun allows you to stop the flow of caulk instantly, reducing waste and keeping your work area clean. Whether you’re sealing large surfaces or finishing up detailed jobs, the ability to control the flow of material ensures professional results with minimal mess. The built-in spout cutter makes opening new sealant tubes quick and easy, while the seal punch eliminates the need for additional tools to break the inner seal, helping you start your job quickly. Constructed from a robust combination of steel, aluminum, and PP, this caulk gun is built to withstand demanding job sites, ensuring durability and long-term reliability.
