Check before you buy

Steel gauge. A lower gauge number means thicker steel. Commercial lockers commonly use 16-gauge doors, while thin-gauge bodies dent and rack easily. Door thickness determines dent resistance and how well the door resists prying.
Assembled vs knocked-down. Check whether the unit ships assembled or knocked-down (KD, flat for bolt-together assembly). KD units are cheaper to ship but need significant assembly, and they are less rigid if fasteners are left loose.
Tier count and width. Single-tier lockers suit long coats and gear, while two- to six-tier lockers trade height for more compartments. Standard widths are 12, 15 and 18 inches. Matching tier height to what you store matters more than the overall size.
Lock type. Choose between a padlock hasp, a built-in key lock, or a combination or digital lock, based on who manages access. Shared or rotating users are much easier to manage with combination or master-keyed locks than with loose keys.
Ventilation. Choose louvered or perforated doors for gym clothes, damp gear or shoes. Sealed lockers trap moisture and odor.
Anchoring. Bolt tall lockers to the wall or floor, or to each other in banks. Freestanding tall steel lockers can tip when doors are opened while the unit is loaded.

What does KD mean on a locker listing?

It means knocked-down: the locker ships flat and you bolt it together yourself, unlike an assembled unit.
