Climb your way to the top with the DGS Ninja Ascending Steps. These steps come in several different variations. Choose from small tops (12" x 9") or large tops (14" x 12") and short bases (11" to 15") or long bases (17" to 24"). The steps require our 5' Wooden Ground Plates, which velcro to Carpet Bonded Flooring. The bases of the steps are designed to bolt into T-Nuts on the Wooden Ground Plate which allow for 6" increments of horizontal adjustments without lifting the Wooden Ground Plate.
