Stegmeier® 1CF122 8' Regular Cantilever Form with Gray Tile Strip and Tie Wire 14 per Box. Stegmeier's cantilever forms are foam forms that attach to the tile on gunite pools and secured with double face tape and tie wires. Set up time is minimal (usually the morning of the pour) and they may be removed early while the concrete is still wet enough to slick finish with a foam profile edging tool. The tie wires are positioned approximately 14 Inch apart and are designed to sever below the surface of the concrete.
