What is the best design choice for OSP when it comes to walls for support structures?

In the context of designing support structures for outside plant (OSP) applications, selecting both end walls only provides structural integrity while minimizing material use and cost. This design focuses on creating a stable and robust framework by utilizing the end walls to bear the majority of the load, which is especially important in environments where structures may be subjected to various weather conditions and physical stresses.

Choosing both end walls allows for effective support and alignment for any equipment or cabling that will be housed within the structure. It also helps maintain the overall shape and rigidity, preventing potential distortion or failure. Moreover, this configuration allows for adequate accessibility on the open side, making maintenance and operations easier without compromising the essential support that the structure needs.

In designing outside plant facilities, cost-efficiency is critical, so the decision to include only the end walls instead of all walls or more extensive frameworks strikes a balance between practicality and performance.
