We bought four of the Small Triangle Sail Sun Shades to use as a replacement for the canvas top on our 10’ x 10’ pergola. The pergola is a metal frame unit, purchased at a local lumberyard, last year. The canvas cover that that came with the unit shows deterioration by the sun, and significant wind damage. We planned to purchase a replacement top, but none will be available until August, when season is winding down. The Small Triangle Sail Sun Shades required a little extra modification, as a 10’ x 10’ square is a little small for four Small Triangle Sail Sun Shades. At this time, the Small Triangle Sail Sun Shades are holding up fine in the sun and relentless Nebraska winds. We will repurchase the Small Triangle Sail Sun Shades, if, and when replacements are required.
