The Apollo Hi-Riser includes the outstanding features of the standard Apollo along with the added benefit of rising over obstacles on top of the apparatus.

Also, the Apollo Hi-Riser rotates easily down to a low-profile position for portable operation and comes complete with an automatic drain valve.
