These Booster Spacers are made of molded plastic and are designed to be inserted inside your oyster bags. They create volume within the bag and allow a better through-flow of water. This results in a more regular growth and a better shaped oyster. When not in use, they are easily stackable. The reinforcing along the base on this version provides added strength and rigidity
This booster is also available in a black non-reinforced version.
We have also written a blog describing how the booster spacer system works which you might be interested to read.
