A caged ladder can look simple on paper, but a long climbing route deserves more planning than just repeating ladder sections. Once climbing height increases, users benefit from better route segmentation and safer landing logic.
Rest platforms are useful when the project basis, internal safety policy, or actual climbing condition suggests the route should be broken into more manageable sections. They also help when the top access point is not a simple single landing.
Rather than assuming a universal rule, the best approach is to review total rise, user behavior, site policy, and transition details together during drawing review.
