Componenti in plastica di qualsiasi genere, sotto il galleggiamento, neanche morto!

Designed and made in New Zealand, the Recessed Skin Fitting body and nut are moulded from glass-reinforced nylon composite. High strength, high-modulus glass fibres provide dramatic strength, stiffness, toughness and dimensional stability. These properties allow a significant weight reduction over metallic fittings.
TruDesign Skin Fittings eliminate the corrosion and electrical bonding problems associated with metallic fittings.
