Lead heights are kept deliberately small because the portion of the cable that leads into a cabinet or enclosure should enter with a gentle angle and minimal projection. When this lead is constrained to less than one-quarter of the available vertical space, it reduces the likelihood of snagging, kinking, or applying excessive tension as cables are installed, moved, or serviced. A smaller lead height helps maintain the proper bend radius and keeps terminations and connectors from experiencing lateral stress, which protects the integrity of the installation and makes future cable management easier. If the lead were larger (as the other fractions imply), it would increase snags, routing complications, and risk of damage during pulling and rework, compromising the setup.
