I have had this product for several years and just added 2 more rails. I love the sleek, clean design and the options on the hooks/baskets/shelving. I have one 84" & two 48", I'm buying another rail tomorrow to hang my extension ladder on. I do agree that the shorter rail should be 50".  I do have mine mounted on studs at both ends with 16" stud balancing but I maxed several holes to get it to fit. I wish they made hooks for mounting kayaks- take the hint Rubbermaid.  Great product!!
