SECO 5131-01-FLY 2 ft Aluminum Pole Extension - Flo Yellow

Overview

The SECO 5131-01-FLY 2 ft Aluminum Pole Extension provides a simple way to add height to compatible survey poles, prism setups, GNSS equipment, and other accessories using standard 5/8-11 threaded connections.

The extension measures 2 ft (61 cm) long with a 1 in (25 mm) outside diameter. A female 5/8-11 thread on the bottom connects to a compatible pole or extension, while the male 5/8-11 thread on top accepts additional sections or compatible surveying accessories.

Its Flo Yellow finish improves visibility in the field and makes the extension easy to identify among other equipment.

2 ft Extension Length

The SECO 5131-01-FLY adds:

• 2 ft
• 61 cm

of length to a compatible survey setup.

The fixed section length makes it easy to account for the additional height when building a pole or instrument configuration.

The completed prism, antenna, or target height should always be verified before entering it into a total station, GNSS controller, or field software.

Standard 5/8-11 Threads

The extension uses standard surveying threads on both ends:

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

The female lower connection attaches to a compatible male-threaded pole, mount, or extension. The male upper connection can support a compatible prism, antenna, adapter, target, or additional extension section.

Stackable Design

Multiple compatible extensions can be connected together when additional height is required.

The male and female 5/8-11 connections allow sections to be added in sequence, creating a modular setup for applications where a standard pole does not provide enough reach.

When stacking multiple sections, crews should consider the increased leverage, wind exposure, and overall stability of the completed setup.

1-Inch Outside Diameter

The extension has an outside diameter of:

• 1 in
• 25 mm

This slim profile keeps the extension lightweight and compatible with appropriate clamps or mounting accessories designed for 1-inch OD poles.

Aluminum Construction

The SECO 5131-01-FLY is made from aluminum for a combination of strength, durability, and manageable weight.

Its construction makes it suitable for repeated field use while remaining easy to transport with other survey equipment.

Flo Yellow Finish

The extension features SECO’s Flo Yellow finish for improved field visibility.

The bright color makes the section easier to identify on active jobsites, in survey vehicles, and among other poles and accessories.

• Prism pole extensions
• GNSS antenna extensions
• GPS base setups
• Survey target mounting
• Construction layout
• Monitoring applications
