Twiggi and Cayman are available in both 'Stainless Steel’ and 'Black Edition'. The base of the grille in both cases is high quality stainless steel. In addition to that, the 'Black Edition' versions have an indestructible black epoxy coating of maritime quality. This makes the 'Black Edition' as robust as the 'Stainless Steel' version. Twiggi and Cayman are suitable for both cast floors and tiles of 4 mm+ thickness.
