Thank you for viewing. This is a wall-mounted tension system for 2x4 lumber that can be installed without damaging walls or ceilings. It uses the power of jacks and springs to firmly secure the 2x4 lumber. This is a simple and safe solution for installing shelves and pillars without damaging homes where nails cannot be driven into the ceiling, floor, or walls. White, set of 2 Unopened, unused. One item's outer plastic container was slightly cracked, so only the contents (screws, main body, and sticker) will be shipped. For reference, what you can do with one Wallist: By erecting a single pillar, you can hang hats, bags, school bags, and coats, or display clocks, calendars, and picture frames without making holes in the wall. Having several expands the possibilities.
