Designed for football referees, CHAMPRO Yard Marker Chain Clips are a convenient tool for keeping track of yardage. The black plastic slider moves along the orange nylon strap to mark yardage from 0-50 in 5-yard increments. The end metal clip allows the marker to be fastened to a chain, keyring, or to the ring at the other end to wrap around the wrist. The yard marker measures 14” long, and each order contains 12 Chain Clip Yard Markers.
