DuoLift® joists

Providing substantial height flexibility within four stackable components, DuoLift® removes the common problem of having to order varying height pedestals for a single area. Height-adjustable from 15mm, DuoLift® makes accurate height-setting easy, and is self-levelling from 35mm upwards.

With DuoLift®, you can quickly achieve a level support system that won’t rot, split or host algae. DuoLift®’s range of feet, pedestals, risers and cradles are even suitable for use in damp environments.
