Scratch and dent means what it says. A bench picked up a scuff, a scratch or a dent somewhere between the plant and the floor, and the mark is on the surface rather than in the structure. Nothing about how the bench works changes.
What is on the page right now: an adjustable height bench with a 30-inch deep hardwood top, and a heavy-duty adjustable height bench at 48 inches wide by 28 inches deep with a painted steel top. Both raise and lower, so the work surface sets where the job needs it.
These are one-off units, not stocked items. When one sells it comes off the page, so the list here changes as units move.
