ABSTRACT:
A tennis net strap that both measures and holds center of tennis net at regulation height above court is described. Strap is of minimally stretching material and employs cam buckle with preferably a short secondary strap with hook-and-loop material as back up security measure. On opposite end of strap from buckle, a metal tab keeps strap end clean and from fraying. A single-end snap clip anchors strap to court. A primary measuring mark is located on strap near tab, which is aligned with slot in cam buckle to ensure strap is fastened at correct length. With cam buckle closed, strap is rotated until secondary mark on strap 36 inches from end of metal tab aligns with top of net, with tab just touching court surface. A third security measure is preferably employed in which now aligned areas on both sides of installed strap are fastened together through net.
