Product Description

Designed specifically to allow decks to be built over concrete slabs, particularly where ground clearance is limited, the KlevaKlip adjustable joist support is a crafty device. Comprised of a base plate, two vertical bolts and a joist hanger, they are ideal for use over concrete with built-in fall or an irregular surface.

Purpose-built for the application, KlevaKlip adjustable joist supports are quick and easy to use without the need for various packers to achieve a perfectly level deck. They’re an ideal option when the step-down from your door to concrete slab is between 100mm and 220mm, with the height of your deck governed by the length of bolt used. And because the KlevaKlip adjustable joist support ensures joists remain off the concrete, they eliminate the threat of rot through the bottom of the joist.

KlevaKlip adjustable joist supports are designed to accommodate 45mm wide treated pine joists, but can also be used with hardwood joists providing they are screwed into the joist hanger rather than nailed.
