Here's the story how one man got Home Depot to take a defective brand of ladders off the shelves. On March of 2004 he was repairing the trim on his house, standing on the ladder about 16 feet above the ground when the ladder abruptly dropped down about an inch starting a chain of events leading to his injuries.
The cause of the ladder kicking out was directly related to the initial drop at the Shu-Lok base causing the Shu-Lok to become dislodged and unsafely repositioned. The effect was how the ladder unsafely without my control attempted to reposition itself.
The higher he climbed up the ladder, the more the equilibrium changed and caused more force to be displaced against the structure of his home and caused
pressure to be dispersed differently at the Shu-Lok base. He believes the ladder's initial drop was followed immediately by an unsafe repositioned Shu-base configuration combined with his weight distribution which caused enough downwards force resulting in a KICK-OUT motion. This initiated the ladder to slide away from his house with him on it.
As a result this ladder design can fail causing him and other people to fall and become seriously injured. In his case it resulted in at least a 16-foot fall on his concrete driveway, breaking both wrists and shattering his left kneecap into at least five pieces.
