The SELECT Sock Screens and Frame set the standard in durability. SELECT'S screens are trusted by major league, college, and high school teams across the country. SELECT uses the most advanced manufacturing process that ensures the highest quality and tightest knots made today. Every net is made from High-Density Polyethylene (HDPE). Each strand of the netting is treated with a complex UV protection enabling the net to endure extreme weather conditions. SELECT Sock Screens are constructed of 1.5" 16 gauge steel with ever-welded™ legs. The frame snap-locks together for easy assembly. The bottom line is that you cannot buy a better Sock Screen.
