  • Modular drawer system
    Patent number: 6003924
    Abstract: A modular drawer system is particularly adapted for installation on vehicular load-carrying surfaces such as the beds of pickup trucks and the cargo-supporting floors of utility vehicles to transport and store tools, machinery parts, building materials and the like in an orderly, easily-accessible manner. The system's modularity provides highly variable alternative stacked configurations and volumes to accommodate different vehicles. Although lightweight and easily installable, the system nevertheless is highly resistant to displacement under the dynamic forces typically experienced in vehicular applications, and is also highly resistant to vertical loading.
