After a deer somehow got into our backyard pool enclosure two weeks ago and severely damaged 12 screen panels, I carefully analyzed the existing screen, researched my options to buy suitable replacement material, and then selected this particular Phiferglass screen. After being delivered as promised in perfect condition, it turned out to be an exact match. I've only installed 4 of the new screen panels using new 5/16" flat spline, as the weather is rather chilly and I'm a 'newbie' at this, but I couldn't be more pleased with the results. Granted, I've had a learning curve which necessitated 2 re-installations for the first panel replacement, but the final results thus far have been better than I could have ever expected.
