The Topcon RL-200 1S Single Grade Laser is engineered for professional contractors who demand precise, repeatable slope control on demanding job sites. Whether you're managing a large grading operation, pouring concrete slabs, or cutting excavation grades, this complete kit delivers the accuracy and working range to keep your crew productive from first shot to final grade. Purchased through Express Tools, an authorized Topcon dealer, you receive a genuine factory kit backed by Topcon's warranty and our dedicated tool support team.
Overview: Built for Grade Work in the Real World
The RL-200 1S excels where consistent single-axis slope control matters most. Its self-leveling mechanism compensates automatically for minor setup variations, and the rugged housing is sealed against dust and moisture so it keeps working through the grind of everyday site conditions. Pair that with the included LS-80X machine or hand-held receiver and you have a system ready for grade checking, fine grading, pipe laying, and concrete forming without any additional accessories required. Setup is fast, operation is straightforward, and the 2,600-foot diameter working range means one instrument covers virtually any residential or commercial site layout.
