What is the primary purpose of using locking plates on turnbuckles?

The primary purpose of using locking plates on turnbuckles is to ensure that the tension remains consistent and secure throughout the rigging system. Turnbuckles are designed to adjust the tension in ropes, cables, or rods, which is crucial for maintaining the integrity and safety of a rigging setup. By incorporating locking plates, you effectively prevent the turnbuckles from unintentionally loosening due to vibrations, environmental factors, or load shifts. This locks the adjustment in place, providing stability and reliability in the rigging components.

In contrast, while aesthetics, ease of installation, or weight reduction may be considerations in rigging, they do not serve the fundamental function that locking plates provide in maintaining the necessary tension in a system. The security of the setup is paramount in all rigging applications, making the locking plates an essential component for effective and safe operation.
