This is perfect for levelling a slightly uneven surface. Manufactured from 92% recycled tyre tread and rubber, RynoDeck fixed height cradles are resistant to mould, bitumen and algae. These resistances make these adjustable decking cradles the perfect accessory to achieve a height and allow a structure to maintain the strength and durability throughout its life. Use these adjustable decking cradles to change the height of a deck by a minimal amount and the airflow allowed underneath the structure could reduce rotting. A square 100mm x 100mm base supports the entire deck structure with capacity for 30mm – 48mm width capacity.
