Improve on-field safety with the Champion Sports Bolco-Style Safety Base Set. Constructed from a single piece of durable, flexible rubber, these bases provide a cushioned surface to help reduce injury risk during slides. The tapered sides are designed to minimize tripping when running the bases, while the universal aluminum stanchion allows compatibility with both male and female ground anchor systems. Suitable for baseball and softball use, each base measures 15" L x 15" W x 3" H. Ground anchors are not included.
