Colorbond fence height extension kits

Each kit extends one panel: two post extensions, a rail, your chosen insert and a bag of colour-matched screws. 300 mm or 600 mm, standard 2.36 m or extended 3.1 m panels, every Colorbond colour.

How ordering works: this is an enquiry-based catalogue – there is no online checkout and prices are confirmed by quote. Choose a product, press Enquire About This Product (or call 0421 233 434) and tell us the quantity, colour and your suburb. We confirm the current price, lead time and delivery or pick-up options. Installation is available across Sydney for most items.

Match the post profile first

Colorbond fence posts come in three profiles – Lysaght, Slimline and Standard (double-ribbed). The extension post must match yours to sit neatly and fix securely. Look at the top of one of your posts, compare it with the picture, and tell us which one when you enquire (or send a photo and we will identify it).

Extensions also rely on the existing posts and footings being sound. If a post is loose or rusted at the base, an extension is not the right fix – we will tell you.
