This high quality, light weight telescoping Tabletop Riser extends from 14 to 24 inches and is great for elevating our lights from display surfaces, such as tabletops, countertops, shelving or podiums. Just like our other mounting options, lights attach to the Tabletop Riser via an 18mm track located at the top of the telescoping pole. And at the base is an extra-wide adjustable clamp capable of the clamping to surface edges from 0.25 to 3.5 inches thick. So clamping to even the thickest of display surfaces is a breeze!
