17ft Multi-Position Foldable Aluminum Ladder

【MULTIPLE FUNCTIONS】This adjustable ladder can be as an A-frame ladder, trestle-and-plank，an extension ladder, a staircase and 90-Degree ladder. 【PORTABLE DESIGN】The frame is constructed of a special alloy that makes it lighter than comparable industrial-rated ladder, which makes it easier to move. 【NON-SLIP FOOT PADS】 Widened foot pads have the surface made of non-slip texture, which increases the friction to provide a safer working experience. Wider texture steps than the comparable ladders ensure safety. 【PUSH KNOB LOCKING HINGE】A push knob for locking the ladder to make the different function position fixed. And the embedded buckle will be automatically locked if the ladder is opened. 【DURABLE MATERIAL】 Made of High-grade Aluminum, durable and tough enough to resist rust and aging and serve you a longer time.
