Product Details

Setting up a levelling post and bearers for the sub-structure of your deck can be tedious and time consuming, but not with Adjustable Bearer Support (ABS). ABS are suitable for use where decks are typically from 300mm to 600mm off the ground. These heights are achieved by using different height joists and bearers.

Material

Carbon Steel

Finish

Hot-Dip Galvanised

Features & Benefits
  • Quick and easy to use when setting height of your bearer.
  • Ideal for use on areas where the ground has a "fall", to provide a level bearer height.
  • Heavy duty and fully hot-dip galvanised ensures long life-span without failure.
  • Locking nuts ensure absolute rigidity.
  • Can be used to prop up existing bearers or floor joists that have sagged over a period of time.
  • Use with 45mm to 100mm wide bearers of various heights.
  • Variety of uses include the building of ramps, stairs, post supports, adjusting the rafter support to achieve the pitch on a skillion roof
Installation
  1. Place in position - 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 freestanding deck (i.e. not attached to any fixed structure – eg house).
  2. Use a masonry bit to drill the holes and clean out the dust. Masonry Drill Bit Diameter: 10mm (if using the THD10060MG). Drill hole depth: 85mm
  3. Fix with 2 x M10 Titen HD x 60mm long (THD10060MG) anchors to ensure strength and stability of base.
  4. Adjust to the height required. Note: Full turn = 3mm adjustment. Do not wind higher than 290mm to the bottom of bearer height.
  5. Locking nuts should be fully tightened at all times. This is especially important when the thread is wound out near its maximum height.
  6. Secure the bearer to the support using two (2) M10 bolts with washers and nuts.
Note:
  • Provides a bottom of bearer height from 160mm to 290mm.
  • On a free-standing deck (i.e. not attached to a fixed structure), regardless of bearers meeting span requirements, a minimum of six (6) Adjustable Bearer Supports should be used.
  • If you require a bottom of bearer height of 160mm, you will need to cut the bottom 20mm of the threaded rod.
  • Do not wind the Adjustable Bearer Support higher than 290mm to the bottom of bearer height.

  1. ABS have a download capacity of 16kN. This is approximately equivalent to 4m2 of 1.5kPa floor load area
  2. The above information is a “practical” rather than an “absolute” document. There will be a number of ways to achieve the heights mentioned with different sized bearers and joists, however the installer should always be mindful to operate within the Simpson Strong-Tie product parameters and relevant joist/bearer span tables.
  3. The product has a supplied lowest height of approx 175mm. In order to achieve 160mm, the bottom 20mm of the threaded rod needs to be cut off.
