SECO 5500-11 8.5 ft TLV Prism Pole with Adjustable Tip

Overview

The SECO 5500-11 8.5 ft TLV Pole is a professional adjustable survey pole designed for prism positioning, robotic total station work, construction layout, and general field surveying.

Its wear-resistant aluminum construction is powder coated and silk screened for long service life. The pole extends to 8.53 ft (2.60 m) and collapses to 4.97 ft (1.516 m) for transportation and storage.

SECO’s TLV locking mechanism includes a soft rubber tightening knob that remains easy to operate while wearing gloves. A 40-minute vial is built directly into the lock, while dual 0.01 ft and centimeter graduations help operators set and verify the correct pole height.

SECO TLV Locking Mechanism

The SECO 5500-11 features a TLV locking mechanism that secures the telescoping pole at the selected working height.

The lock uses a soft rubber knob that provides a comfortable grip and remains easy to tighten or loosen while wearing work gloves. This helps crews adjust the pole efficiently during cold weather, construction work, and other field conditions where gloves are commonly required.

Integrated 40-Minute Vial

A 40-minute level vial is built directly into the TLV locking mechanism.

The vial provides a clear visual reference for keeping the pole vertical over a survey point, monument, stake, nail, or other reference location. Maintaining a plumb pole helps position the mounted prism or accessory directly over the intended measurement point.

Dual 0.01 ft and Centimeter Graduations

The pole includes dual measuring scales for engineering and metric workflows:

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

These graduations allow the operator to set and confirm the pole height before entering it into the total station, data collector, or field software.

Adjustable Tip

The SECO 5500-11 includes an adjustable tip for fine-tuning the overall pole height.

This allows the pole configuration to be adjusted for specific prism-height requirements, field procedures, and surface conditions. The final pole height should always be verified before collecting measurements.

Powder-Coated Aluminum Construction

The pole is manufactured from aluminum and finished with a durable powder coating.

Silk-screened graduations provide clear height references, while the wear-resistant construction is designed for repeated use in surveying and construction environments.

The red and white finish improves visibility across active jobsites and makes the pole easier to identify among other field equipment.

Adjustable Working Length

The SECO 5500-11 has the following specified length range:

• Extended length: 8.53 ft (2.60 m)
• Closed length: 4.97 ft (1.516 m)

The adjustable design provides additional working height when needed while allowing the pole to collapse for transportation and storage.

Ideal Applications

• Robotic total station surveying
• Conventional total station surveying
• Prism positioning
• Construction layout
• Boundary surveying
• Topographic surveying
• Utility mapping
• Grade staking
• Engineering fieldwork
