Norix has refined the concept of its next generation of inmate storage tank boxes—the Citadel Property Storage Container. Designed to securely contain 2.2 c.f. of inmate items, the containers offer increased safety, extreme durability and long-term value, according to the company. Molded in high-impact copolymer, the boxes and their matching lids feature rounded corners for added safety, while its ribbed design delivers structural integrity. Allowing users to stack units inside one another for space savings, the cases can each be padlocked for more security and molded-in channels enable lids to slide properly onto boxes. Citadel containers can be configured to fit underneath steel bunks as pullout drawers.
