You’re Looking At.

01

overhead impact

Crushed caps and split seams caused by branches, canopies, and low-clearance structures.

02

water intrusion

Failed joints and aged sealant that let moisture reach cargo, framing, and interior panels.

03

rail misalignment

Shifted headers, opened seams, and loose fasteners that weaken the corner connection.
