These are folding, removable tree stand steps for non-climbing tree stands. Great for leaving a "non-climbing" tree stand in place for the hunting season, just remove the steps as you decend, leave the bolts in place,(they blend-in) , re-attach the steps as you ascend for your next hunt. Remove the bolts with the included tool at the end of your hunting season. Folding feature makes for easier storage and carrying. Extra bolts included, one step is non-folding. A box/socket tool is included for installation and removal of bolts. The steps are made of aluminum,, spray painted with flat grey galvanizing epoxy, the bolts are blackened steel, they have been used for a season, I will accept cash only.
