The SHIJING SHTCL6103 Tension Level Suction Cup (140mm Single Cup) is a professional-grade manual suction and alignment tool manufactured by Zhejiang Shijing Tools Co., Ltd.. It is specifically engineered to provide both powerful vacuum adhesion and fine-tuned mechanical tensioning for handling, positioning, and leveling large-format tiles, stone countertops, slabs, and glass panes.
Key Specifications & Design Features
• Cup Diameter: 140mm (Single Cup configuration), optimizing the surface area footprint for precise structural adjustments on narrow or tight joints where larger 200mm lifters might not fit.
• Tension Leveling System: Features a mechanical threaded rod adjustment mechanism allowing tile installers and stonemasons to pull joints together or adjust the vertical plane relative to adjacent slabs.
• Premium Rubber Base: Constructed using durable, heavy-duty rubber (typically Buna-N or high-grade natural rubber) designed to hold a tight vacuum seal on smooth, polished, or minimally textured surfaces without staining the material.
• Ergonomic Handle: Built with a rigid metal or high-impact composite lever handle to safely engage and lock the suction cup with minimal effort.
