Our Poly Toeboard has been completely redesigned with cross-link poly-ethylene and UV stabilizer for maximum durability against man and nature. With this design, you eliminate the problems of rusting that metal boards have and its solid construction eliminates chipping and cracking that you can experience with wood or fiberglass boards. So not to interfere with the thrower, we have also added sleeved counter sunk mounting holes for through bolts. The depressed bottom allows the board a snug fit over the throwing circle. This board meets all official specifications.
