Topcon 329250010 Pipe Laser Trivet Stand for TP-L3, TP-L4 and TPL5 Series TENTHS

The Topcon 329250010 Trivet Stand with tenths graduations is the precision accessory built for contractors and municipalities who work in decimal-foot measurements. Designed as an OEM companion to the Topcon TP-L3, TP-L4, and TP-L5 pipe laser series, this adjustable-pole trivet stand eliminates on-site unit conversions and keeps slope documentation accurate from the first segment to the last. When fractional-inch errors compound over multi-hundred-foot pipe runs, tenths-graduated tooling is the difference between a passing inspection and a costly re-grade.

Overview & Jobsite Applications

Built for underground utility and drainage installation crews, the Topcon 329250010 seats securely inside pipe and positions the laser at the exact invert elevation called out on decimal-based civil drawings. The tenths scale on the adjustable pole lets the operator read and record elevations directly in decimal feet — the same units used by surveyors, inspectors, and project engineers — without a conversion chart or calculator. Whether you're laying gravity-fed sewer mains, storm drain laterals, or irrigation conveyance pipe, this stand keeps your crew moving and your grade records clean.

• Compatible with Topcon remote target receivers for long-run visibility
• Reduces documentation errors on projects with decimal-foot elevation datums

Job Applications

Municipal Sewer Mains: City and county crews working off decimal-foot benchmarks can read invert elevations directly from the pole without unit conversion, accelerating as-built documentation and speeding up inspector sign-offs.

Storm Drain Laterals: Tight slope tolerances on curb-inlet laterals demand accurate, repeatable laser placement. The trivet stand holds the TP-L series laser at the exact invert while the tenths scale lets the operator dial in the specified slope in a single adjustment.

Irrigation & Conveyance Systems: Agricultural and commercial irrigation contractors using decimal-foot designs from civil engineers can match the drawing datum directly, reducing back-checks and re-work on long, flat-grade pipe runs.

Grading Inspections & Record Drawings: Inspectors and survey crews verifying installed grades use the tenths scale to record as-built invert elevations in the same decimal format required by most municipalities and state DOT authorities.

Frequently Asked Questions

What is the difference between the tenths and eighths trivet stand versions?

The tenths stand (329250010) is graduated in decimal feet (0.1 ft increments), matching the units used on most civil engineering drawings. The eighths version is graduated in fractional inches and suits trades that work in imperial inch-based measurements. Choose tenths if your project plans and elevation benchmarks are expressed in decimal feet.

Which Topcon pipe lasers is this stand compatible with?

The 329250010 trivet stand is designed for the Topcon TP-L3, TP-L4, and TP-L5 pipe laser series. The OEM mounting interface provides a direct, tool-free fit with no aftermarket adapters required.

Can this stand be used in partially flooded or muddy trench conditions?

The trivet stand is built for real trench environments where standing water and mud are common. The three-leg design seats on the invert of the pipe for a stable base, and the materials are suited for wet conditions. Always wipe the laser mounting head before seating the tool to maintain a clean connection.

Does the adjustable pole lock securely at intermediate heights?

Yes. The adjustable pole is designed to lock at any height within its range, holding the laser at a consistent elevation throughout a pipe run. This is critical for maintaining grade accuracy over long segments where any movement of the stand would introduce slope error.
