SPAX Lift decking supports made of sturdy plastic create a load-bearing and height-compensating base for the substructure of wooden terraces. At the same time, SPAX Lift separates the substructure from the floor and thus prevents rising damp from getting into the wood. They can be adjusted in height by a simple turning movement. SPAX Lift 3.5/5 and SPAX Lift 5/9 can bear loads of up to 800 kg. Two sizes are available: With SPAX Lift 3,5/5, height adjustment between 35 and 50 mm is possible, with SPAX Lift 5/9 it is between 50 and 80 mm. Attention: When using SPAX Lift Extension, the load capacity of SPAX Lift 3.5/5 and SPAX Lift 5/9 is reduced to 400 kg. This means for you: Problem-free alignment of the substructure is also possible on old decking.
