The ChrisNik True Plumb 16TPL1000 offers an easy and accurate way to test your equipment for plumb. Make sure your grade rod is straight and adjust it in seconds. The True Plumb fits all brands of prism poles with a 5/8-inch thread on top and a point at the bottom. The model 16TPL1000 works with non fixed-height telescoping rods. With the addition of the Adapter (16TPLADAPTER), you can also use your 16TPL1000 with fixed-height GPS rods. Or you can purchase the 16TPL2000, which works with both standard telescoping and fixed-height GPS prism poles 2 m long. The True Plumb also lets you check and adjust your hand-held bubble levels.
All you have to do is mount this prism pole adjuster on a wall and calibrate it (mounting hardware is included). Then insert your rod and rotate it 360° to check that it is straight and plumb. The ChrisNik True Plumb is made of welded steel for lasting durability and comes with a 3-year warranty.
