Granite Seam Setter Kit, 2-Pack, 6-Inch Vacuum Cups

Granite seam setter clamps deliver strong vacuum suction and precise leveling to align slabs fast and reduce lippage during countertop installation. This 2-pack set uses 6 in nitrile rubber suction cups with a vacuum pump to hold tight on stone, tile, ceramic, glass, and marble while you fine-tune seam width and height. Adjustable angle control helps handle corners and multi-angle seams with less rework.

Built for installers who need repeatable seam alignment without fighting shifting slabs, these seam joiner tools help keep surfaces flush while you set adhesive and tighten alignment. Use the anti-static dust cloth to prep both the suction cup and work surface for a more secure hold, then fine-tune spacing and height until the seam lines up. Pack everything into the included Oxford cloth bag for transport between jobs. Grab yours today and keep your next countertop, tile, or marble slab install on track.
