SECO 5144-02 50 cm Carbon Fiber Pole Extension 1.25" OD

Overview

The SECO 50 cm Carbon Fiber Pole Extension is a lightweight, rigid extension designed to add height to compatible GNSS rover poles, prism poles, laser poles, and other surveying equipment. Measuring 50 cm (19.69 inches) in length with a 1.25-inch (32 mm) outside diameter, it provides additional working height without adding the bulk of a comparable metal extension.

Standard 5/8"-11 female threads on the bottom and 5/8"-11 male threads on the top allow the extension to connect directly to compatible survey equipment or stack with additional sections when greater height is needed.

Key Features

• Carbon fiber survey pole extension
• SECO part number: 5144-02
• Length: 50 cm (19.69 in)

• Lightweight, rigid carbon fiber construction
• 5/8"-11 female thread on the bottom
• 5/8"-11 male thread on the top
• Stackable with additional compatible extension sections
• Helps add pole height while limiting added weight
• Compatible with a wide range of GNSS, prism, and survey accessories

Add Height Without Excess Weight

The SECO 5144-02 is well suited for field setups that require more elevation, including applications where the receiver or prism needs to clear vegetation, equipment, barriers, or other obstructions.

Its carbon fiber construction offers excellent stiffness with lower weight than many metal alternatives, helping reduce operator fatigue while maintaining a stable pole setup.

Common applications include:

• GNSS RTK surveying
• Prism pole setups
• Construction layout
• Topographic surveys
• Utility mapping
• Control surveys
• Laser mounting
• Specialized elevated measurements

Stackable 5/8"-11 Threaded Design

The extension uses standard surveying threads on both ends:

• Bottom: 5/8"-11 female
• Top: 5/8"-11 male

This allows it to connect directly between a survey pole and mounted accessory or combine with additional compatible extensions. The stackable design gives crews the flexibility to adjust pole height for different projects without replacing the entire pole system.

Carbon Fiber Construction

Carbon fiber delivers a strong balance of rigidity, durability, and low weight. This makes the extension a practical choice for surveyors who need added height while keeping the complete pole assembly manageable during long field days.

Its corrosion-resistant construction is also suitable for regular outdoor use in demanding survey and construction environments.
