Double vacuum cup design: The Granite Seam Setter uses a double vacuum cup arrangement with a quick knob adsorption function to prevent panel shifting when handling large granite surfaces. This enables safe, precise positioning and is well suited for construction projects. Accurate tile positioning: Advanced fine adjustment knobs reduce rework by keeping seams aligned within 0.5 mm. By controlling suction cup spacing, it delivers consistent precision during seam standardization tasks in tiling projects. Improved tool longevity: Built with strength materials and a pressureresistant design that performs in damp or heavyload environments, ensuring lasting durability and dependable loadbearing capabilities for demanding operations. Improved control feature: Nonslip ergonomic handle provides a secure grip with increased friction and textured surfaces. The shape matches the palm for smooth handling when repositioning furniture or installing fixtures, reducing hand strain during extended use. Applications and use scenarios: Granite countertop and slab installation in kitchens or bathrooms: position, align, and stabilize large granite panels and seams with confidence. Commercial tiling projects: set floor or wall tile seams with precise spacing to minimize rework and ensure consistent results. Repositioning heavy stone fixtures in damp or crowded spaces: move granite panels or stone fixtures securely without slipping, ensuring safe, efficient operations.
