Topcon 56929 Adjustable In-Pipe Target Optically Enhanced for Pipe Laser

Built for Green Beam Pipe Lasers — Maximum Contrast Where It Counts

The Topcon 56929 Blue Adjustable Target Kit is purpose-engineered to solve the contrast challenge that pipeline and sewer crews encounter when working with green beam pipe lasers. While the targets are blue, the optical engineering behind this kit is specifically tuned to interact with green laser wavelengths — delivering a sharp, easy-to-read laser spot even in challenging underground or daylight conditions. Designed as a direct accessory for the Topcon TP-L5 and TP-L6 pipe laser series, this kit gives contractors the visibility and accuracy they need to keep pipe grades on spec from manhole to manhole.

Overview and Jobsite Applications

Pipe laser alignment depends on more than just the instrument — the target is just as critical to a clean shot. The 56929 target kit features an adjustable design that accommodates varying pipe diameters, keeping the target centered in the pipe bore for a true, repeatable reading. Whether your crew is laying gravity sewer mains, installing storm drain infrastructure, or running conduit bores, this target eliminates guesswork and reduces the risk of costly grade errors. The blue surface finish creates high-contrast differentiation from the green laser dot, making it easy for installers to confirm alignment at distance without second-guessing the shot.

Job Applications

Gravity Sewer Main Installation: Maintain precise invert grades on sewer mains where even minor deviation causes long-term flow problems. The 56929 target keeps your grade shot consistent pipe joint to pipe joint.

Storm Drain Construction: Storm infrastructure demands both grade accuracy and speed. The adjustable target fits a variety of RCP and HDPE pipe diameters common in storm drain work, so one kit covers multiple pipe sizes on the same project.

Horizontal Directional Drilling and Bore Pits: When crews are pulling conduit or casing through a bore, confirming alignment with a clearly visible target reduces costly steering corrections and rework.

Municipal Utility Rehabilitation: On rehab projects where existing inverts must be matched precisely, the 56929 target gives inspectors and contractors a reliable visual reference that leaves no ambiguity about laser position.

Frequently Asked Questions

Why is the target blue if it is designed for a green beam laser?

Blue and green are complementary in terms of optical contrast. The blue target surface absorbs surrounding light differently than the green laser wavelength, which causes the green laser dot to appear sharper and more defined on the blue background compared to a white or yellow target. This is why Topcon specifically engineers blue targets for their green beam pipe laser accessories.

Will the Topcon 56929 work with red beam pipe lasers?

The 56929 is optimized for use with green beam pipe lasers, specifically the Topcon TP-L5 and TP-L6 series. While it may physically fit in a pipe, the optical contrast benefit is designed around the green laser wavelength. For red beam lasers, Topcon offers separate target accessories engineered for that spectrum.

What pipe diameter range does the adjustable target accommodate?

The adjustable design on the 56929 is intended to cover the common pipe diameters used in gravity sewer and storm drain construction. For specific minimum and maximum diameter specs, refer to the Topcon product documentation included with the kit or contact our product support team for confirmation before ordering.

Is the Topcon 56929 covered under Topcon's warranty?

Yes. As an authorized Topcon dealer, Express Tools sells the 56929 as a genuine OEM accessory, which means it is covered under Topcon's standard accessory warranty policy. Contact our team with any warranty questions and we will assist in coordinating with Topcon on your behalf.
