Are inserts permitted on the inner profiles of rear corner posts?

Inserts are not permitted on the inner profiles of rear corner posts. This is primarily to maintain the structural integrity and damage protection that dry vans must adhere to. The corner posts play a crucial role in the overall strength of the trailer, contributing to its ability to withstand external forces during transit. Any modifications or insertions could compromise that strength, leading to potential safety hazards.

The standards set for dry vans are designed to ensure that all components remain intact under the stresses they will encounter. Items like inserts could interfere with the ability of corner posts to absorb energy or could cause weakening in these critical areas. For this reason, the prohibition on inserts helps ensure the trailer performs as expected over time and remains safe for use. Meeting these structural guidelines is essential for manufacturers and operators when considering the durability and reliability of cargo containers.
