Abstract
A portable step for climbing up and down elongated objects, such as trees and poles, is provided by a one-piece member formed to cooperate with a belt-type fastening means and is essentially T-shaped in cross-section with a horizontal leg portion constructed and arranged so that the step will not twist to the side when the user places his weight thereon.
