Each vent in this 8-pack kit measures 8 inches long and 2.6 inches wide, constructed from durable, heavy-duty plastic for long-lasting performance in various weather conditions. The vents' specially designed convex shape, featuring bottom-facing, inward-tilting holes, enhances functionality by preventing water entry and promoting better air circulation within the container. Installation is straightforward, requiring only three bolts per vent for secure attachment to your shipping container. The downward-facing vent holes facilitate easy setup and efficient operation. These vents significantly improve airflow, mitigating issues such as excessive heat, humidity, and pressure inside shipping containers. This enhanced ventilation also reduces condensation, protecting your cargo. Each vent includes a rubber gasket to ensure a tight seal, effectively preventing rainwater intrusion and safeguarding the container's contents from water damage. Color variations may occur between different batches, but this does not affect the vent's functionality.
