Every paddock or pit space in the world sits on flat ground, right? Dream on! Many are out of level by as much as 12" in ten feet! In order to level your platform you end up scrambling for any piece of wood or other makeshift shim to make up the difference in level.
MK Technologies has solved the problem by offering kits of 4 levelling feet extensions that can be attached to the platform in between the feet and the nut they screw into.
