The 4-Door Steel Storage Locker, model STL-4D-900, is an unbranded steel personal storage solution with a clean, utilitarian light gray matte exterior. Its symmetrical layout organizes four equal compartments across two vertical columns and two horizontal tiers, with each door fitted with a recessed clear plastic label holder at the upper section, a polished chrome vertical pull handle with an integrated key cylinder centered below the label holder, and punched louvered vent slots at the lower door section. The freestanding unit sits on a fully welded base frame, with external stamped steel butt hinges positioned to allow each door to swing fully outward for unobstructed interior access. Constructed from cold-rolled steel, the locker features a thicker gauge for door panels than its main body, finished with a light gray epoxy-polyester powder coating suited for indoor use. Fixed welded cold-rolled steel shelves separate upper and lower compartments in each column, with hardware including zinc alloy cam locks supplied with two keys per compartment. The structure supports defined static loads per compartment and across the full cabinet, with tested durability ratings for hinges and lock mechanisms to support regular repeated use, and coating resistance to withstand standard indoor environmental conditions. Each compartment operates with an independent keyed lock to restrict access to assigned users, while integrated door vents support continuous r exchange to reduce odor buildup from stored items. Label holders accommodate standard name cards for easy user assignment, and fixed shelves enable sorted storage across separate spaces, with no adjustable shelf positions included. This locker fits a wide range of both commercial and light residential-adjacent spaces, including office staff areas, school changing rooms, factory employee zones, public gym and recreation facilities, and small retl or workshop environments needing organized, secure storage for personal effects, workwear, athletic gear, or small supplies. It supports dedicated use for four assigned users per unit. For procurement planning, note the unit ships in a single carton, with a short assembly time for knockdown configurations, and standardized loading quantities for common ocean freight contners to support bulk order planning. Panel gauge specifications align with standard commercial light-duty locker designs, so buyers should confirm final bill of materials details with suppliers for large-volume or high-traffic deployments, and ensure installation on level floors for stable freestanding placement.
