Our replacement nets are 1-3/4″ square-hung mesh, available in either high-density polyethylene or nylon. Double layer construction with machine sewn poly rope borders. Sock-style for easy installation over your existing frame. Cutout dimensions are 42″x42″. Please call us if you're unsure how to measure your frame or which type of netting is right for your application. We generally recommend PE for outdoor applications, whereas nylon is a good choice for indoor facilities.
