This tree step is made by API Outdoors and is called the " Skyhook Ultralite Treestep" --the other type very similar, same style, it is made by Game tracker, identical steps and the model # for this step is 3155. You will more be able to get the Game Tracker model..I find this step (game tracker 3155) a litter easier on the hand while holding on to climb...the shyhooks have sharper grooves compared to the game tracker.
