Product Description

What is the KlevaKlip Adjustable Joist Hanger?

The Klevaklip Adjustable Joist Hanger has been designed specifically to enable decks to easily be built over concrete slabs in areas where limited ground clearance is available. It is ideal for use when the step-down from your door to your concrete slab is between 4 inches (minimum) and around 12 inches.

What is the USA Version?

The USA version  is not suitable for use in Australia as they are designed to suit 2 inch wide (metrically measured at 38mm) US timbers. The bottom plate is pressed to suit US Bolts. (Australian M10 will not fit!!!)

Advantages of the Adjustable Joist Hanger

  • Keeps Your Joists off The Concrete And Free Of Unwanted Moisture Ingress. This Prevents Joist-Rot Through The Bottom Of Your Joists.
  • Is Ideal For Use On Area Where The Concrete Has Built In “Fall” – To Provide A Level Deck.
  • Height Of The Deck Is Determined By The Length Of Bolts Used.
  • Uses Standard 12mm Dynabolt Anchors For Holding Into Concrete.

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.

The clever people from KlevaKlip have released the Adjustable Joist Hanger. 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”.

The KlevaKlip Adjustable Joist Hanger is registered for Patent approval. It is simple to install and can be used with suitably treated timber joists with a width of 2 inches.
Note: Hardwood joists should be screwed to the joist hanger rather than nailed.
