The pool slats are what is most visible from the pool shutter device, so they play the biggest role in your selection. You can choose from two types of materials - classic PVC slats or polycarbonate (PC) slats. We offer slats in a standard 60×14 mm profile or as Premium Clean in a 67.5x16.5 mm profile (polycarbonate solar and ALU slats only). They can be positioned ABOVE or BELOW the pool design. They can be used for indoor pools as well as for outdoor pools.
