This Hang and Hold Bar is designed by Totally Tiffany for Crafter's Companion. This bar is designed to be a clip-on desk storage system when you have a small space but a need for lots of storage. The bar clamps to the side of a table, coffee table, workbench, or countertop and will allow you to add additional Hang and Hold accessories (sold separately) to create an even larger craft space. This Hang and Hold bar measures 24 wide and each clamp measures 2 wide x 3.5 high. The bar requires a smooth, flat surface in order to attach which also needs to be between 1/2 to 2.5 thick to achieve the best performance from this product.
