This Diamond Slicer for 7 ft. pool table only. This simple product is a training / aiming aide for the player that uses the diamond system or just needs the help improving on banking/kicking skills. Installation is very easy. Peel off the backing of one sticker at a time and follow, connecting each diamond around the table. Trim off excess sticker wherever the sticker overhangs on a pocket. The fit and finish is nice and clean. You can lift and reposition the sticker but the sticker basically has one life; reposition sparingly. Use it when practicing the cushion system or in a lesson. Designed for a 7 ft table. 24pcs/set.
