SECO 5530-20 12 ft TLV-Style Construction Prism Pole

Overview

The SECO 5530-20 12 ft TLV-Style Pole is an economical Construction Series pole designed to provide dependable everyday service at a lower purchase price.

Its two-section telescoping design uses aluminum inner and outer pole sections and extends to a maximum specified length of 11.81 ft (3.60 m). Dual graduations in decimal feet and centimeters support both engineering and metric measurements.

A TLV locking mechanism secures the pole at the selected height, while the integrated 40-minute vial helps the operator maintain a vertical setup. The adjustable tip and hardened-steel points provide added durability and flexibility for construction layout, surveying, and prism positioning.

Economical Construction Series Design

The SECO 5530-20 is designed for field crews that need a functional, adjustable pole without the additional cost of premium features.

Its straightforward Construction Series design makes it a practical option for construction layout, prism positioning, grade staking, and general surveying applications.

Two-Section Telescoping Pole

The pole uses two telescoping aluminum sections to reach a maximum specified length of 11.81 ft, or 3.60 m.

The adjustable design provides the extra working height needed for taller prism and measurement setups while allowing the pole to collapse for easier transportation and storage.

Aluminum Inner and Outer Sections

Both the inner and outer pole sections are manufactured from aluminum.

This construction provides a balance of durability, manageable field weight, and resistance to common jobsite conditions.

Dual 0.01 ft and Centimeter Graduations

The SECO 5530-20 includes dual measuring scales:

• Decimal feet graduated to 0.01 ft
• Metric graduations in centimeters

This allows the same pole to be used for engineering-foot and metric field measurements without changing equipment.

TLV Locking Mechanism

The TLV locking mechanism secures the telescoping inner section at the selected working height.

Once the pole is adjusted, the lock holds the section in place to help maintain a consistent prism or accessory height during measurements.

Integrated 40-Minute Vial

A built-in 40-minute level vial provides a visual reference for keeping the pole vertical.

Maintaining a plumb pole helps position the mounted prism or surveying accessory directly over the intended measurement point.

Adjustable Tip and Hardened-Steel Points

The adjustable tip allows the lower pole configuration to be fine-tuned for the field setup.

Hardened-steel points provide a durable contact surface for repeated use on soil, pavement, concrete, and other common jobsite surfaces.

Red and White Finish

The red and white finish improves visibility across active construction and surveying environments.

The contrasting colors also make the pole easier to identify in work vehicles, equipment storage areas, and larger jobsites.

Ideal Applications

• Construction layout
• Prism positioning
• Grade staking
• Boundary surveying
• Topographic surveying
• Utility layout
• Site preparation
• Engineering fieldwork
