Designed for safety on the field, the Champion Sports Bolco Style Major League Base Set features a durable, one-piece rubber construction measuring 15” x 15” x 3” with tapered edges to prevent tripping. This set of three universally-compatible bases (fitting both male and female ground anchors) utilizes a strong aluminum stanchion for secure attachment, and the highly flexible rubber offers a soft landing surface for players sliding in, minimizing the risk of injuries like scrapes and sprains. Commonly used in various levels of baseball and softball, from youth leagues to professional fields, this set provides a safe playing experience for all. Note: ground anchors are sold separately.
