When equipment needs protection without sacrificing access, the Chief PAC735B secure storage shelf gives integrators a practical enclosure strategy. It is designed for rack mount equipment, PCs, codecs, and other large AV components that require controlled access in conference rooms, classrooms, carts, and shared technical spaces. The shelf supports 19 in-wide equipment up to 4 RU, making it a strong fit for standardized AV and IT deployments. This model is built for installations where security and organization matter. Available in keyed locking options A, B, and C, it helps limit access to the hardware inside while keeping the system serviceable for authorized users. Up to three units can be stacked vertically and bolted together starting at the base of the cart or stand, which is useful when consolidating multiple devices into a single footprint. Vent holes are included to support airflow around enclosed gear, helping maintain thermal performance in dense installations. For teams that need a secure, professional storage layer for high-value equipment, the PAC735B delivers a more controlled deployment than open rack shelving.
