Description

Overview

The SECO Tripod Adapter 3-1/2" x 8 to 5/8"-11 allows surveyors to mount instruments or accessories with a 5/8"-11 thread onto tripods equipped with a 3-1/2" x 8 threaded head. Precision-machined from anodized aluminum, this adapter provides a secure, stable connection while expanding the compatibility of existing survey equipment.

Whether integrating modern GNSS receivers, tribrachs, prism systems, or laser equipment with older-style tripods, the SECO 2120-00 offers a simple and reliable solution without the need to replace existing equipment.

Adapt Legacy Tripods for Modern Equipment

Many older survey tripods feature a 3-1/2" x 8 mounting thread, while today's GNSS receivers, tribrachs, prisms, lasers, and other surveying accessories commonly use the industry-standard 5/8"-11 thread.

The SECO 2120-00 bridges these two standards, allowing modern equipment to be mounted securely on existing tripods. It's an economical solution for extending the life of older equipment while maintaining compatibility with newer instruments.


Durable Anodized Aluminum Construction

Manufactured from precision-machined anodized aluminum, the adapter is engineered for professional field use. The lightweight construction minimizes additional weight while the anodized finish provides excellent resistance to corrosion, scratches, and everyday jobsite wear.

Its precision threads ensure a secure fit that helps maintain instrument stability during surveying and construction layout operations.

  • Surveying
  • Construction layout
  • GNSS receiver setups
  • Total station accessories
