I received 2 gearwall sections each 8ft in length, they are versatile and can be cut to any length to fit any where you need them.  They are heavy duty and can hold pretty much anything you want to hang.  They allow for more useable garage or workshop space by moving items up and out of your working space.  
The walls have made my work shop so much better now that I have more space to actually work. [This review was collected as part of a promotion.]
