Everloc is a real revolution in the realms of suction-fix products. A DIY (do-it-yourself) dream. When the suction cup is applied, a silicon ring first adheres to the surface and creates an airtight seal around the suction cup. This patented Everloc system is probably the only suction cup system that delivers what it promises: Long-lasting adhesion and consistent load-bearing capacity. Easy to assemble. NO tools, drills or glue. Comes with everything you need. Dorm proof suction! No need to worry about damaging your walls and best of all this is suction that actually works. This Everloc 14" Double Towel Rail gives you the extra space you need to hang your shower towels, wash cloths and hand towels. This towel rail is ideal for placement in dorms that have sliding closet doors. With sliding doors over the door hooks that typically hold towels cannot be used, but our Double Towel Rail can be. Once you set it up you won't need to worry, your towels will hold and you'll be all set. Suction to your door, wall or tile.
