FAQ

Q1: Will a fully loaded 21 inch handheld hard case be too heavy to carry?

A1: The case itself is lightweight, but the final weight depends on the contents. We recommend users plan their load carefully. For extremely heavy loads, we suggest two people or the use of carrying tools. The one-piece molded handle design provides a secure grip. Q2: Does it offer the same protective performance as the smaller model?

A2: Yes, the core protective performance is exactly the same. We all use the same IP67 testing standards, the same level of sealing strip principles, and high-quality engineering plastics. The larger size does not result in a reduction in the protection rating. We guarantee that all our products maintain consistent reliability in terms of the stated protection rating.
