Safest: The combination of benefits only offered by your X-IT Ladder make it safer to use then all other competing ladders. X-IT is the only emergency ladder that works with every window/wall thickness and width. Strongest: Your X-IT Ladder is designed and tested by applying a 1,000 lb load in the middle of any step. This is the same test done on professional ladders and exceeds ASTM standards for emergency ladders. No other emergency ladder comes close. Smallest: Your X-IT 2 Story Ladder is similar in size to a 2 liter soda bottle while 2 story plastic step emergency ladders are similar to larger travel luggage. This is particularly important when storing and using your ladder. Imagine a child putting a suitcase out a window! The size differences become exponential as ladder length increases: X-IT is by far most compact. Lightest: Your X-IT 2 Story Ladder is 6 lbs. Chain style 2 story emergency ladders are 15 lbs. Imagine a child putting a 15 lb large suitcase out a window! The weight differences become exponential as ladder length increases: X-IT is by far the lightest. Easiest To Use: Just hook your X-IT Ladder to the window and drop it outside. It will deploy automatically, tangle free. Other ladders require set-up and complicated deployment techniques. Chain ladders are known to tangle when deployed. The red carrying handle on the latter is brittle, but the paracord and steps are in perfect working condition.
