StrataRise Flexi-Level 1250 Pedestals are adjustable from 12mm to 50mm. The height can be increased by using one or more optional clip-in 20mm high base extension pieces (sold separately). The cradles are supplied complete with a clip-in moulded rubber base.

Easy to use and to adjust

Designed to replace the original Uni-Level cradle (Rubbertech, Ryno), the new Flexi-Level Cradle brings a number of new features and increased capability. It is easier to use, stronger, now has water drainage, can be fixed to the beams and is supplied complete with a moulded rubber base. It is a simple and strong Joist Support, with levelling, for floors and decking. The small footprint assists installation in areas with restricted space. The cradles provide a fast and easy solution for levelling and supporting joists for flooring and decking on balconies, roof terraces and other firm surfaces. They are designed for use with standard 2″ (44 to 48mm) wide timber joists, keeping them above the base substrate and, importantly for exterior applications, above the drainage level of the roof or base.

    Great product if you don’t want to spend hundreds levelling out ground! We put slabs directly onto turf, then used this product with a wooden shed base to level up. Saved myself 900, as this is what we we’re quoted to lift turf and level.

    Great produc

    Theses are a little costly but make levelling a deck easy, particularly on uneven surfaces. Be careful not to place too near the edge if you want to plinth the deck though – lesson learned!

    Wanted to level a slope under timber. Hope they will prove to be strong enough over time. Easy to fit adjustable feet for joists.

    Did the job well, raising the joists for my decking, a little pricey and one negative, hard to wind up when the joist resting is on i

    Loved using these. I used 50 putting decking on old slabs. Levelling with a fall in one direction took about 45 minutes. Good fit on the joists – not too tight, easy to adjust, fixed to joists with 2 woodscrews each after levelling. Joists well above any standing water after a storm. Worth the money for sure.

    This product is awesome, did one project directly onto flags and they made the job so easy. I have now done a further 2 and purchased again and again. An expense your dont budget for but worth every penny in saved time and stress.

    When I decided to lay a new decking area over an old uneven concrete base, I was worried about how to get the deck to be level and correctly angled to enable rainwater to run off. These levelling joist supports are just the job – very solid and easy to use on the decking subframe. Naturally these supports do lift up the subframe even at the lowest setting and in retrospect I would have ordered lower height timber joists to compensate. However, this is a minor point and I am very pleased with the results and would highly recommend.

    So I brought these when building a deck as they looked a damn sight easier than individually propping up the 2″x6″ timber frame with old paving slabs and wedges etc.
    I was right, once put together and using an extra spacer or two if required (I was building over a wonky old Patio) they were simplicity itself to adjust to the right height and maintain the correct fall across the deck.
    I have since installed an above ground kids swimming pool (about 3 tonnes of water) on the finished decking and they haven’t budged a millimetre!
    They may be a little on the pricey side, but they will save you hours and hours of head scratching, I highly recommend these supports.

    If you have variable height footings for your deck these units make it easy
    to level everything up.
