What aspect of the ATC with prussic setup enhances system cleanliness?

The aspect of the ATC with prussic setup that enhances system cleanliness is the attachment of a rigging plate to the anchor side. Using a rigging plate can help to organize and manage multiple connections in a more efficient manner. It serves as a dedicated point for aligning various components, which can reduce the likelihood of tangling and create a more streamlined setup. This organization minimizes the risk of having loose ends and stray hardware, contributing to a less cluttered and more efficient rescue system.

In contrast, using a thicker rope may affect the compatibility with certain hardware, potentially leading to a bulkier setup rather than enhancing cleanliness. Minimizing carabiner use can be beneficial, but without the structured organization provided by a rigging plate, it might not lead to significant improvements in cleanliness. Similarly, reducing the length of the prussic could impact the functionality and efficiency of the system without directly addressing cleanliness concerns. Therefore, the use of a rigging plate is key in maintaining a tidy and organized system while performing a rescue operation.
