Sealant Gun with 18:1 Thrust Ratio: Ideal for medium-viscosity sealants – delivers extra power while maintaining flow. Ensures controlled, even application of thicker acrylics and professional-grade compounds.

Includes Drip-Stop Mechanism: Thanks to the integrated spring mechanism, the plunger rod automatically retracts slightly after releasing the trigger – preventing unwanted dripping for a clean and professional workspace.

360° Rotatable: The cartridge holder of the mastic gun is fully rotatable, allowing the cartridge to turn freely in place – for maximum flexibility and comfortable handling at any working angle. Reliable silicone gun applicator.

Integrated Puncture Tool: The cleverly concealed puncture tool in the handle quickly clears clogged silicone or acrylic nozzles without the need for extra tools - ensuring a smooth and consistent material flow.

Maximum Force & Durability: With an impressive 350 kg (3500 N) of thrust and double heat-treated steel plates for superior stability, the caulk gun delivers reliable performance even under intensive use.

【Switch at Will of High & Low Flow Rates】WORKPRO mastic gun allows for switching between high and low flow rates. Pull the trigger handle downwards, the high of setting thrust ratio 18:1 for use with adhesive materials. Push the trigger handle upwards, the low setting of thrust ratio 9:1 for use with acrylic materials.

【Drip Controllable】Press down on the front of the red button, this process stops the caulk from flowing and allows for clean, smooth transitions and less mess to clean up. Press down towards the rear of the red button, this mode keeps constant pressure on the tube for providing smoother action and quicker working.

【Allows for Effortless Maneuvering in Tight Areas】The sealant cartridge gun with a rotating barrel can effortlessly reach hard-to-reach places. A rotating shaft is designed to allow easy maneuvering in tight areas. WORKPRO's half-barrel frame caulking gun is ideal for standard size 10 oz cartridges.

【Smooth Roud Rod for Less Force Required】Smooth plungers allow more control and more thrust to push the caulk. The smooth round rod with spring-loaded thumb release offers a quieter and less effortful project than a ratchet rod. The puncture tool can also be used to clear the spout of the tube if it becomes clogged.

【Comfortable Grip】The trigger with a cushion grip improves grip comfort and prevents your fingers from hurting when you are caulking. The handle and trigger of the cartridge gun are made of ergonomics plastic, which is comfortable for a long time using.
