The Metro Wire Security Module Kit transforms a standard 24" wide shelving unit into a secure storage area with ease. This kit is designed to enclose one or more sections of any Super Erecta Shelving unit, fitting perfectly between shelves spaced 20" apart. It is compatible with 24" wide shelves in lengths of 30", 48", and 60". The kit includes side panels, back panels, and a door, which features hasps for two padlocks for enhanced security. The door conveniently slides under the upper shelf when opened, providing unobstructed access without taking up additional space. Please note that posts and shelves are sold separately.
