When a laser is to be set on a flat surface where the laser beam is not centered in the pipe, use the Spectra 1230 Heavy Duty Trivet Plate. Using this system, the elevation of the laser beam can be set by either measuring down from a grade offset hub outside the trench or up from the floor of the manhole to the beam.

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 inch, 12 inch, or 15 inch 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 inches
