2" Booster for 20" Plyobox by Powermax
A fast and safe method to increasing your plyobox height by 10%. The top platform is constructed of steel and covered with 10mm thick rubber surface (like our plyoboxes). Straps are constructed of heavy duty nylon and have an adustable, locking buckle to secure to the top. A great method for increasing your workout without having to buy a whole new box.
