If you press button 4, the rod transforms into a climbing pole up to 50 feet long, as you specify. In surfaces as hard as granite, a spike at the bottom and three hooks at the top anchor the pole. Horizontal bars 3 inches long fold out from the sides, 1 foot apart, forming a ladder. The pole can bear up to 4,000 pounds. More weight or lack of solid anchoring causes the rod to revert to its normal form.
