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.

		Maximum Load Area(m²)
Bearer Width	Bearer Support Height (mm)	2 Span Continuous	3 Span Continuous
70mm	290	3.2	3.6
70mm	230	4.1	4.7
70mm	160	4.6	5.2
90mm	290	2.2	2.5
90mm	160	3.5	4.0
45-50mm**	290	3.2	3.6
45-50mm**	160	4.6	5.2

** When using 45 or 50mm bearers, in order to achieve the above load areas, the bearer must be packed out from to "L-bracket" to ensure the centre of the bearer is directly above the centre of the bearer support column.

Note: The height to the top of your Joist will depend on whether your joists are “hung” inside the bearer (in which case top of joist height usually equals top of bearer height), or whether your joists are fixed to the top of your bearers (in which case the height of your joist should be added to the top of bearer height to achieve top-of-joist/bottom-of-deck height).

For your convenience, below is a span table for joists and bearers which should be cross referenced with the Adjustable Bearer Support span table above.
