⚡ At a Glance
  • Load Capacity: Supports 2000kg for heavy decking and structural loads
  • Best for: DIYers and builders installing raised timber decking, patios and balconies
  • Not ideal for: Projects that need adjustments outside the 28mm to 36mm range

Adjustable pedestals allow height control to suit 50mm and 40mm timber joists. A ten-piece pack supplies repeatable supports for small to medium raised decking runs.


Consistent levelling - with adjustable height 28mm to 36mm

The pedestal heads permit fine height adjustment across a 28mm to 36mm range, matching the footprint of 50mm and 40mm timber joists. Height variance compensates for uneven substrates to help achieve a flat decking plane.

Accurate adjustments reduce the need for shimming and rework, making it quicker to lay boards straight. Repeatable settings help maintain alignment across multiple joists.

Heavy-duty support - with 2000kg load capacity

Robust construction is designed to bear substantial static loads up to 2000kg across each support location. Materials and geometry distribute weight to reduce stress on individual joists.

High load capacity gives peace of mind under densely furnished decks or heavy foot traffic. Structural integrity reduces the chance of sagging over time.

Faster installs and consistent spacing - with a pack of 10 adjustable pedestals

Ten matching pedestals arrive ready to position and adjust, enabling cohesive spacing and uniform heights across a decking section. Simple placement and adjustment workflow suits repetitive installations.

Having a matched set speeds installation and keeps layouts consistent, useful on patios or balcony repairs. Less time spent measuring and levelling translates to fewer on-site delays.
