The SPAX Lift terrace supports made of sturdy plastic create a load-bearing and height-adjustable base for the substructure of wooden terraces. At the same time, SPAX Lift separates the substructure from the ground, preventing rising moisture from reaching the wood. They can be easily adjusted in height with a simple twist. The SPAX Lift 3.5/5 and SPAX Lift 5/9 can support loads of up to 800 kg. Two sizes are available: the SPAX Lift 3.5/5 allows for height adjustments between 35 and 50 mm, while the SPAX Lift 5/9 accommodates heights between 50 and 80 mm. Note: When using the SPAX Lift Extension, the load capacity of the SPAX Lift 3.5/5 and SPAX Lift 5/9 is reduced to 450 kg. This means that aligning the substructure is also possible on old terrace surfaces without any issues.
