Adjustable Joist Support (AUS/NZ) - Box of 24

Adjustable Joist Support (AJH50G) Information

As many houses these days are built on concrete slabs, there is often a shortage of height available to build a regular decking substructure of stumps, bearers and joists etc. Indeed, many houses have a slab for a patio area set down only approx 100mm below the height of the main housing slab. Fixing timber battens directly to concrete slabs is regarded as a poor building practice due the moisture uptake into the batten which will rot out the batten way before its normal lifespan. This scenario has made it very difficult for people to enjoy the relaxed lifestyle of having a timber deck at their doorstep.

We have now have released the Adjustable Joist Support for 50mm wide Steel or Hardwood joists which allows you to adjust the "top of joist height" from 118mm (using 60mm length bolts + 100 x 50mm joists) to 230mm (using 120mm length bolts + 150mm x 50mm joists).
