Box of 40 Pedestal Flooring and Levelling Cradles - for shed (Elephant and castle SE11)

I bought these from Bradplas Ltd if you want to check out their website. There is a box of 40.

"The Decking Cradle Pedestal Flooring & Leveling System - Base and Cradle consisting of a rubber base pad and interlocking cradle - Used to support timber joists over solid substrates and to aid in leveling floors.

The cradle design allows for a standard 2-inch joist to sit within the cradle providing support to the joists to reduce movement in the floor and to also allow connecting joists over longer spans. The cross-sectional design provides added support for cross members/noggins.

The height of the base and cradle is 14mm. 2 x fine adjustment levelers are included at 3mm, each provides incremental increases of 17mm and 20mm if used."
