Granite Seamless Seam Setter Stone Countertop Vacuum Suction Cup 12/15cm Seamer seamless Marble Work Slab Joining leveling Tool feature: After the plate absorbs the working surface, the splicing of the plates is adjusted at a stable speed. If the working surface is large, two splicers should be used to splice simultaneously. If you cannot operate the vacuum cleaner at the same time, you must make fine adjustments to each device to prevent the suction cup and the working surface from moving sideways at the same time. When joining small boards, make sure they are on a level surface and do not block each other. When connecting for the first time, hold down for one minute, check it, and turn it back on after one minute.
