Height Adjustable Deck Support 

2nd Generation model. Improvement on our previous model in every area


  • Even quicker to adjust with the new adjustable nut design
  • New design allows you to adjust the support "after the fact", which means you can adjust it AFTER the frame is screwed to it and after the base is bolted down. Useful to make micro adjustments in case of wood swell or if it sagged years down the track without having to unscrew anything
  • SUPERIOR rust resistance with Hot Dipped Galvanised base and Darcomet Coating for L-Bracket.
  • Quick Side Locking bolt prevents movement
  • Base of L-Bracket is 87mm (now can support 2 bearers laminated together)

    • Can be used for bearers or joists
    • Quick and easy to use when setting a level height
    • Adjustable height ranges from 37mm - 485mm**
    • For use on low deck applications where floor is not level
    • Hot Dipped Galvanised coating to survive nearly all outdoor weather conditions *
    • Keeps timber off the ground to prevent moisture build up
    • Can be used to prop existing bearers or joists that have sagged over time
    • Variety of uses - decks, ramps, stairs, post supports, kitchen cabinets
    • Fire and termite proof

The adjustable deck supports have been independently tested to meet code.
Tests for Load bearing, rust resistance and fire resistance have been conducted. 
We can provide those test certificates if needed 
Test have been certified by a licensed structural engineer. (see pic)

Steps to prepare footings for floating bracket: (see picture as well)

  • Prepare the ground by digging a small pit.
  • Dill a 25mm pilot hole into the dirt with an auger bit. (optional) 
  • Place the support in.
  • Fill the pit you dug with gravel AFTER you've placed the support into the pilot hole.
  • Compact the gravel with a mallet or similar.
  • Support is ready for framing! No more waiting to concrete to dry. Start building straight away.
