Sigma 51L Double Suction Cup

Sigma 51L double.
The best but also the dearest vacuum suction cup, one that suits every type of tile, textured included, and glass as well. It holds vertical and horizontal loads. It has a strong aluminium body. It locks with plastic levers that engage without pressing hard on the tile. These cups stand out for how comfortably they sit in the hand. Two cups, for instance, suit a 600 x 1200 mm tile nicely. One handles tile up to 600 x 600 mm. Be careful, because tile with microcracks, or with a structure whose layers meet in what amount to microcracks, will not hold on any plain vacuum cup at all – for that you need to look at the pump type. And do note that the tile you are carrying has to be clean.
