The patented 7” box mounting system remains in-ground for a full season of play. The flexible plastic design provides the ultimate in safety and the wide opening makes cleaning out dirt a snap. These release bases are constructed with the exclusive “progressive release” design, providing the latest safety technology. In the case of uncontrolled slides, the “progressive release” action allows the base to flex until enough force is applied to “pop” the base free from the mount, unlike any standard base. Proven over 15 years of play, “progressive release” bases out-perform standard bases.

Available as a set of 3 and in two sizes: 14″ or 15″ (Little League rule 1.06 approved in 14″ only). Includes ground mount anchors and tapered plug. Optional Drag Plug sold separately (replaces tapered plug when bases are not in use).
