Adjustable Joist Support (AJH38G) USA 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 4 inch 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.

The clever people from KlevaKlip have released the Adjustable Joist Support . This product, the only one of its type on the market, not only lifts the joists off the concrete, but allows you to adjust the "top of joist height" from 4 ¼ inches (using 2 ½ inch length bolts + 2 x 4 inch joists) to 8 ½ inches (using 5 inch length bolts + 2 x 6 inch joists).

The KlevaKlip Adjustable Joist Support is registered for Patent approval. It is simple to install (installation instructions can be found at and can be used with suitably treated timber joists with a width of 2 inch and minimum height of 4 inch.

Note: Hardwood joists should be screwed to the joist hanger rather than nailed.

Please note: - the Adjustable Joist Supports come in standard boxes of 24 units - each unit being a Joist Support + a Base Plate. Bolts, nuts, washers and galvanized screw anchors are standard sizes and must be purchased separately from your hardware store
