Adjustable Bearer Supports should always be fixed with 2 x 12mm x 70mm Galvanised dynabolts or 2 x 10mm x 70mm Masonry bolt or similar to ensure strength and stability of base.
Base plates are recommended to be placed at 90 degrees to the adjacent base plate to provide best possible lateral stability in all directions. This is critically important if building a free-standing deck (ie - not attached to any fixed structure – eg house).
Locking nuts should be fully tightened at all times. This is especially important when the thread is wound out near its maximum height.
Do not wind the Adjustable Bearer Support higher than 290mm to the bottom of bearer height.
Span Table – to be read in conjunction with Bearer span tables. In some instances the placing (distance between bearer supports) of the Adjustable Bearer Supports will be limited by the span capabilities of the actual bearer itself.
