These rubber strips are a wear item on the throwing-arm assembly, cushioning the mechanism and protecting it from impact on every pitch. Swapping in a fresh set of two restores smooth, consistent ball release and protects the surrounding components.
Compatibility: Fits both the Blue Flame (UPM45) and Black Flame (UPM50) pitching machines.
Genuine Louisville Slugger replacement part — includes two strips. Free shipping on orders over $99.
