The Adapt-a-Bat™ from AMACO® allows the use of 8" and 10" bats on larger wheel heads that are not drilled to accept smaller size bats with holes 6" apart on center. One Adapt-A-Bat™, together with several 8" or 10" Plasti-Bats is the perfect solution for high volume production or classroom instruction when smaller objects are being thrown and several students are sharing the wheels. Adapt-A-Bats are constructed from specially formulated, 1/4" thick tough plastic for strength and long life. They won't swell or shrink, are easy to clean and are impervious to water and most chemicals. We recommend storing Adapt-A-Bat™ plastic bats in a slotted rack such as the brent BatMobile or stacked on a FLAT surface to prevent warping. When stacking Adapt-A-Bat™ plastic bats, be sure they are clean prior to stacking. Even the slightest obstruction can cause the bats to warp.
