PRO CERA adjustable feet are suitable for stone terraces in a range of installation heights. Thanks to the innovative solution, the support surface can be flexibly adjusted to gradients of up to 7%; yet it still remains a stable part of the resulting structure. The 4mm wide joint spacers ensure that the stone slabs are automatically aligned with each other and produce a consistent joint width. These can be removed at a predetermined breaking point in order to achieve a range of different installations. A pre-assembled impact sound pad on the support surface reduces the transmission of impact sound between the terrace bearing and the stone slab. The series consists of 6 adjustable feet in different heights. These can be individually adjusted using our Pro expansion rings.
