Carl's Place Golf Room Floor Tile Edge Corners (Qty 4)These corners work with Carl's Floor Tiles and tapered edges to hold both the turf and tiles in neatly, giving your space a nicer finished edge. Designed to work with Carl's Floor Tiles. Corner pieces come in packs of 4. Most setups only need 1 pack. If your layout has inside corners (like a T or L shaped area), you can order extra, and cut the corner pieces to fit.
