The AdirOffice Drop/Lift Wall Rack provides compact and convenient hanging storage in compact areas where space is limited. Just use hanging paper clamps to clip your blueprints, plan drawings, maps and other large files together, then put them in these handy, wall-mounted brackets to keep them organized and close at hand (clamps sold separately). Expertly constructed using solid steel, this wall rack will provide long-term durability and use for years to come. It boasts a 240-lb weight capacity and can hold up to 1,200 documents at once. It's furnished in a finish that will easily fit into and enhance any existing decor. This storage rack can fit any size paper clamps you choose depending on how far apart you install the brackets. Once the brackets are fixed, only one size clamp will fit. Mounting hardware is included for quick and easy installation on any wall. Due to the weight capacity, it's strongly recommended to attach the unit to wall studs or a solid surface. Once installed, clamps lift out and drop in for easy, convenient access to all of your stored documents, making your workplace efficient, organized and the best it can be.
