Professional Pipe Alignment You Can Count On
The Topcon TP-L5B Red Beam Pipe Laser (SKU: 329560112) is built for sewer contractors, drainage crews, and underground utility installers who need reliable, repeatable grade control on every run. Compact enough to seat inside standard pipe diameters yet rugged enough for daily trench work, the TP-L5B delivers the accuracy professionals demand without the complexity they don't need. Express Tools is an authorized Topcon dealer, so every unit ships factory-fresh with full warranty coverage.
Overview & Jobsite Applications
Whether you're laying gravity sewer mains, storm drain laterals, or irrigation force mains, the TP-L5B keeps your invert grades on spec from the first joint to the last. The bright red laser beam cuts through typical daylight conditions, staying visible at distances exceeding 300 feet so operators can confirm alignment without stopping work. The intuitive grade-setting interface lets crew members dial in slopes quickly, reducing setup time and keeping production on schedule. The self-leveling system automatically compensates for minor instrument movement, maintaining a true grade reference even when ground conditions shift beneath the tripod or pipe cradle.

Job Applications
Municipal Sewer Mains: Set consistent invert grades across long runs of gravity sewer pipe, ensuring proper flow velocity and code-compliant slope from manhole to manhole.
Storm Drain Installation: Align catch basin laterals and trunk lines to designed grades, preventing ponding and maintaining system capacity under heavy rain events.
Site Utility Contractors: Coordinate underground utility corridors on commercial and industrial sites where multiple pipe systems must maintain precise separation and grade.
Irrigation & Agricultural Drainage: Establish accurate fall on subsurface drainage tile and irrigation supply lines across large parcels where consistent slope is critical to performance.

Frequently Asked Questions
- What pipe diameter does the Topcon TP-L5B fit inside?
- The TP-L5B is designed to seat inside pipe with an internal diameter of 6 inches or greater using the included centering cradle. Adapters are available for larger diameters to keep the instrument on centerline.
- Does the TP-L5B work in bright sunlight without a target?
- Yes. The 635 nm red beam is visible to the naked eye in most daylight conditions at distances up to 300+ feet. For extremely bright conditions or longer distances, using a pipe laser target plate will improve visibility and reading accuracy.
- What is the battery life on a full charge?
- The TP-L5B rechargeable battery pack delivers up to 40 hours of continuous operation on a single charge, making it suitable for multi-day use between charges on active jobsites.
- Is Express Tools an authorized Topcon dealer?
- Yes. Express Tools is an authorized dealer of Topcon positioning and laser products. Every TP-L5B purchased through our store ships as a genuine factory unit and is covered by Topcon's full manufacturer warranty.
