Heavy-Duty Corridor (HDC) KD Wardrobe Lockers

25% heavier than standard KD



Heavy-Duty Corridor lockers, commonly known as HDC lockers, are designed to include all the great features of our Classic KD wardrobe lockers; however, the door gauge is increased to 14 gauge which is 25% heavier than standard 16 gauge doors. To further increase door integrity, we offer our HDC Premier model which includes an 18 gauge full height door stiffener.

HDC wardrobe lockers are sold in various colors and multiple tier options.

Single Tier

The most practical and commonly used style of locker providing ample height for hanging of full length garments.

Double Tier

Where full length hanging of garments is not required or where space limitations do not allow for use of single tier lockers, double tier lockers offer an economical alternative.

Triple Tier

Triple tier lockers are ideal for use where storage of long garments is not required.
