DuoLift® Joist Pedestal

The versatile and user-friendly subframe support system

The DuoLift® joist pedestal system was designed to make installation significantly easier and to ensure successful outcomes. 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.

DuoLift Joist Cradle 15-60mm

Providing an exceptional height range of 45mm, from 15-60mm, the DuoLift® Joist Cradle enables precision height adjustment with 5mm markings on the side and each quarter turn of the adjustment ring representing a 1mm rise or fall. The Joist Cradle allows the installer to adjust the height whilst the joist is in place, locking tabs provide a secure finish once correct height has been determined.


DuoLift Self-Levelling Joint 20mm

Adding 20mm to the height of the supports, the DuoLift® Self-levelling Joint provides easy and effective levelling of a subframe up to 5º, ready for decking installation. Suitable for standing directly onto a solid substrate, or for providing a joint for a higher support.

DuoLift Riser 45mm

The Riser component of the DuoLift® system increases the height in increments of 45mm. It is capable of sitting directly onto a solid substrate under the Joist Cradle and Self-Levelling Joint or forming part of a higher stack with a foot beneath.


DuoLift Joist Foot 45mm

The DuoLift® Foot provides a very stable footing for more elevated subframes, raising the height by 45mm and spreading the load further across the substrate, due to the 220mm base supporting a maximum combined height of 350mm.

DuoLift Acoustic Separation Pad 3mm

Agglomerated cork and recycled rubber pads offer a layer of protection between joist supports and membranes, as well as providing an acoustic benefit.


Simple stackability for height flexibility

Multiple height combinations from four sturdy components. With a selection of components on site, installation delays can be avoided.
