At Valley’s Canvas, we believe in using only superior materials in our projects. For our boat enclosures, we use Sunbrella fabrics and stainless steel tubing, fittings, and fixtures for the frames. Every enclosure is custom fabricated and fitted. The Tenara thread that we use on your boat enclosure will never rot. To prove that, Tenara offers a lifetime GUARANTEE! Strataglass with scratch resistance and O’sea.
