Sokkia 1005155-01 Measuring Rod 25-foot Fiberglass INCHES - Topcon

Reach Further on Every Setup — Sokkia 1005155-01 25-Foot Fiberglass Grade Rod

When standard-length rods fall short on deep cuts, tall fills, or multi-story foundation work, the Sokkia 1005155-01 delivers with a full 25 feet of graduated measurement reach. Built on Sokkia's proven CR-type design, this extended fiberglass leveling rod is engineered for professional contractors and survey crews who need reliable readings across demanding vertical ranges — without repositioning the instrument at every station.

Overview and Jobsite Applications

The 1005155-01 is a multi-section fiberglass rod graduated in inches, purpose-built for construction-grade leveling workflows. Its rectangular fiberglass construction resists warping, moisture absorption, and the hard use typical of active jobsites. At 25 feet extended, it handles basement and underground utility excavations, bridge abutment layout, cut-and-fill grading on sloped terrain, and elevation checks on tilt-up or multi-story concrete pours. The bold, high-contrast graduation markings stay readable at the instrument distances common with automatic levels and total stations.

Key Features

• Extended 25-foot reach reduces instrument repositioning on deep excavation and grade shots
• Rectangular fiberglass construction maintains dimensional stability across temperature and humidity changes
• CR-type graduation pattern for fast, accurate reading at typical instrument distances
• Inch-graduated scale suits U.S. construction workflows and DOT grading specifications

• Compatible with standard rod levels and rod targets for improved accuracy on long shots

Job Applications

Deep Foundation and Basement Excavation: At 25 feet, this rod covers the full depth of most residential and light commercial basement excavations in a single setup, letting the instrument operator read cut grades without walking the level to a new position.

Cut-and-Fill Grading on Sloped Sites: Steep terrain demands large rod readings. The extended length keeps the rod visible from the instrument even when the rodman is significantly below grade, making slope staking and final grade verification faster and more accurate.

Bridge and Retaining Wall Elevation Control: Taller structures require vertical control through a wide range. The 1005155-01 provides the reach needed to check footing elevations at the bottom of a wall form against cap elevations at the top without switching rods mid-pour.

Underground Utility and Storm Drain Layout: Deep storm sewer and utility installations require accurate invert elevations many feet below the instrument. A 25-foot rod eliminates the need for intermediate benchmarks in many standard utility trenching scenarios.

Frequently Asked Questions

What is the collapsed length of the Sokkia 1005155-01?

The 1005155-01 is a multi-section telescoping rod. Each section collapses down for transport, making it manageable to carry and store even at 25 feet extended. Contact Express Tools for exact collapsed dimensions if transport clearance is a concern for your vehicle or job trailer.

Is this rod graduated in feet or inches?

This model is graduated in inches, which is standard for most U.S. construction and DOT grading applications. If you need a metric or feet-graduated version, Express Tools can help identify the correct Sokkia model for your specification.

Will this rod work with a digital level?

The 1005155-01 is a direct-read CR-type rod intended for use with optical automatic levels and visual reading. For use with a digital level such as the Sokkia SDL series, you will need a rod with a bar-code graduation pattern. Call our team if you need help matching a rod to your instrument.

Does Express Tools include a warranty on this rod?

As an authorized Sokkia dealer, Express Tools sells the 1005155-01 with full manufacturer warranty coverage. All orders also include free shipping. Contact our team for current lead times and availability.
