Adjustable Double Suction Seam Puller / Seam Setter Product Description

1. Product Overview

2. Core Features

1. Extendable Knurled Aluminum Tension Bar
    
   Solid anti-slip textured aluminum tube with adjustable length to fit different seam widths. Multiple silver fine-tuning knobs precisely control pulling distance and locking force for uniform compression. Lightweight yet rigid, no bending under long-term tension.
2. Large Yellow Vacuum Suction Cups
    
   Wide-diameter black elastic rubber suction bases form tight airtight vacuum on smooth polished stone, glass and tile surfaces. Independent quick-release plastic levers on each suction cup allow fast adsorption and detachment without scratching delicate finished surfaces.
3. Symmetrical Balanced Pulling Structure
    
   Double suction point layout applies even horizontal tension on both sides of the joint, effectively flattening uneven slab edges and reducing offset gaps, avoiding single-side stress that causes stone cracking.
4. Multi-Point Fine Tuning Knobs
    
   Two independent adjustment knobs on each bar end for micro calibration of flatness, easily fixing minor height differences between slabs without extra tools.
5. Detachable Replaceable Rubber Pads
    
   Worn suction rubber liners can be replaced separately, cutting long-term maintenance costs and extending the whole tool’s service life.
6. Compact Portable Design
    
   Lightweight split structure, easy to carry to construction sites and store without occupying excessive warehouse space.

3. Applications & Usage Scenarios

Main Purposes

• Pull and level granite, marble, quartz and artificial stone slabs for seamless countertop joints
• Eliminate gaps and high-low edges between large-format ceramic rock slabs and wall tiles
• Fix stone panels tightly during seam glue filling, curing and subsequent polishing
• Align vanity tops, kitchen islands, window sills and decorative wall stone during installation

Applicable Working Scenarios

1. Stone processing factories and customized countertop production workshops
2. Kitchen & bathroom cabinet decoration and interior installation teams
3. Large rock slab tiling and villa renovation construction projects
4. Glass deep processing and high-end decorative stone fitting sites

4. Operation Precautions

1. Fully clean stone powder, residual glue, water and oil stains on slab surfaces and suction rubber pads before use; dirt will break vacuum seal and cause slipping during tensioning.
2. Place two suction cups symmetrically on both sides of the stone seam, fully press the lock levers to exhaust air completely for stable adsorption.
3. Rotate the aluminum bar’s fine-tuning knobs slowly to pull slabs together; never over-tighten violently to prevent thin stone edges from chipping or cracking.
4. Only apply on smooth, intact, non-porous polished surfaces; not suitable for rough, cracked, porous or uneven stone materials.
5. Inspect rubber suction pads regularly; replace hardened, cracked or deformed pads timely to maintain stable vacuum performance.
6. Release the tension screw first before flipping suction levers to detach the tool, avoiding sudden pop-up scratches on polished stone surfaces.
7. Wipe the aluminum bar and suction cups clean after daily use, store in dry ventilated space to prevent metal oxidation and rubber aging from sunlight.
8. This tool is only for seam pulling and positioning, not for lifting or transporting heavy stone slabs; do not bear vertical load.
