The Rackitfile™ product is made of a durable steel construction and has 22 rungs for hanging a set of alphabetical files in either standard or legal size. The Rackitfile mounts easily to most surfaces and comes with wood/particle board screws, the best drywall anchors on the market and a mounting template with instructions. A mounted Rackitfile protrudes 6 inches from the wall and fully loaded is 21 inches from top to bottom (the unit itself is 12 ¾” tall). If you are concerned about weight, the straight pullout weight rating for the whole unit mounted with our drywall anchors is 90 lbs with a shear of 140 lbs. In other words you would run out of space before you could put too much weight in a Rackitfile. A Rackitfile™ is designed to utilize vertical space almost doubling the overall horizontal filing space which means you almost have 12 inches of filing space. Even if you do need more room, the Walfile System is expandable by just adding more Rackitfile™ units.
