The Spectra Laser 1230 heavy duty invert plate is a one piece cast aluminum support plate that provides automatic self leveling of a pipe laser in 10 in., 12 in., or 15 in. pipe diameters. The 1230 invert plate can be used alone, or used along with the 1239 Universal Fixed Pole (sold separately) to form a pipe laser trivet for set ups on the manhole bottom, outside of the manhole, or in pipes larger than 15 in.
