All of our gauge options have 1-3/4″ or 1-7/8″ squares, so a baseball or softball will not fit through the netting mesh. The nylon gauge options go from #18 to #96, and our most popular choice is the #36. The #36 is also very popular for Lifeline Netting for boating. The #36 gauge netting is available in black and white. The #21 netting is available in black or white. All other baseball/softball gauges are available in black only. Poly nets only come in #36 gauge and is available in black only.
