SECO 2153-10-051 Quick Release Adapter to Bayonet

Overview

The SECO 2153-10-051 Quick Release Adapter to Bayonet is a compact survey accessory designed to convert a compatible quick-release tribrach adapter into a bayonet-style prism connection.

It allows compatible prism assemblies with a bayonet base to be mounted and removed quickly without repeatedly threading components together. This makes it useful for traverse setups, control work, and other applications where prisms need to be attached or swapped efficiently.

Key Features

• Quick-release adapter to bayonet connection
• SECO part number: 2153-10-051
• Converts a compatible quick-release tribrach adapter to a bayonet-style mount
• Supports compatible bayonet-base prism assemblies
• Allows fast prism installation and removal
• Useful for traverse and control setups
• Compact survey mounting accessory

What Is a Bayonet Mount?

A bayonet mount is a quick-connect attachment system that locks a component in place with a short push-and-twist motion rather than a threaded screw connection.

Instead of spinning a prism onto threads multiple times, the bayonet fitting typically works by:

1. Aligning the prism base with the adapter
2. Inserting it into the mount
3. Twisting it a short distance until it locks

Removal is just as simple—twist the component back to the release position and lift it out.

For surveying equipment, the main advantage is speed and repeatability. A compatible prism can be mounted or removed without disturbing the tribrach setup or spending time threading the assembly on and off.

Quick-Release to Bayonet Conversion

The SECO 2153-10-051 acts as the interface between a compatible quick-release tribrach adapter and a bayonet-style prism.

This allows crews to use bayonet-equipped prisms with a mounting system that otherwise uses a quick-release connection.

The adapter itself does not replace the tribrach or prism. It serves as the connection between the two compatible systems.

Fast Prism Changes

A bayonet connection is particularly useful when prisms are frequently removed for transportation, swapped between setups, or transferred between control points.

Compared with a conventional threaded connection, the short locking movement can make setup and breakdown quicker while maintaining a consistent mounting position.

Useful for Traverse Setups

Bayonet prism connections are commonly used in traverse and control configurations where the prism may be installed on a tribrach-based setup.

Typical applications include:

• Traverse surveying
• Control-point work
• Precision prism setups
• Construction control
• Monitoring
• Boundary surveying
• Engineering surveys
• Total station observations

Compatibility

The SECO 2153-10-051 is described as a Quick Release Tribrach Adapter to Bayonet.

Because bayonet interfaces can vary, the intended prism and tribrach adapter should be confirmed as compatible before ordering.
