Adjustable 10-17mm & 17-30mm spiral pedestals designed for use in low threshold areas on flat roofs and balconies. These can be used along side our DDP range of pedestals to help overcome threshold issues at the top of the drainage fall. Supplied with 3mm spacing lugs as standard.
Adjustment is achieved by simply twisting the support to go up or down. This support is available in fixed head only.
1mm noise/leveling shims can also be used with this support type.
