This two-pack geartrack by Gladiator spans four feet, giving you a versatile amount of storage anchorage. Hanging anything that requires a hook, like a cabinet or shelving, is a cinch. Since there are two included, you can create a sturdy spot to hang multiple cabinets in a small space. These work well when trying to increase storage space in a smaller environment like a shed or small room. Installation is easy; all you need are a drill and some screws.
