4-Door Lockers

A 4-door locker divides a full-height bay into four compartments, serving four users from a single footprint. It's a high-density favourite for busy changing rooms, schools and shift workplaces where wall space is at a premium but everyone still needs a secure, dedicated compartment.

Our 4-door lockers come from the UK-made Probe range in flat-top and sloping-top styles, standard 300mm and wide-format (380–450mm) widths, and single to triple-width nests. Perforated doors add ventilation for sports kit and PPE, vision panels allow contents checks, and PowerBox versions add secure 3-pin mains, USB-A and USB-C charging for laptops, tablets and phones. Cold-rolled mild-steel bodies, powder-coated finish.

Choose 4-door lockers where you need to maximise users per bay without dropping to small cube compartments. For even higher density see 6, 8 and 10-door units; for laptops and devices, the dedicated charging range.

4 tier, 4 door, 4 compartment — the same thing

Locker terminology is inconsistent across the trade, and it makes specifying harder than it needs to be. A 4 tier locker, a 4 door locker and a 4 compartment locker all describe the same thing: 4 individually lockable compartments stacked in a single column.

Tier counts the levels in one column — so every listing on this page is 4 tier.
Nest counts the columns joined side by side. A nest of 2 is what we list as double width; a nest of 3 is triple width; a nest of 1 is single width.
Bank is the complete assembled unit as delivered. A 4 tier, nest of 3 is a 12-compartment bank.

Nested columns share internal carcass walls, which is why the cost per compartment falls as the nest widens — you buy one set of ends rather than three. It also means a nest cannot be split later, so plan the full run before ordering.

Standard imperial, perforated metric, Vision Panel metric and a PowerBox charging locker — but no 4-door in the standard metric range.

4 door locker FAQs

What is a 4 door locker?

A 4 door locker is a single full-height column divided into 4 individually lockable compartments. The trade also calls it a 4 tier or 4 compartment locker; all three terms describe the same thing.

What is the difference between tier, nest and bank?

Tier counts the levels in one column, nest counts the columns joined side by side (double width is a nest of 2, triple width a nest of 3), and bank is the complete assembled unit as delivered. A 4 tier locker in a nest of 3 is a 12-compartment bank.

Can I split a nested locker bank later?

No. Nested columns share internal carcass walls, which is why the cost per compartment falls as the nest widens, but it also means a nest cannot be split afterwards. Plan the full run before ordering.

What are these lockers made from, and how do they lock?

They come from the UK-made Probe range: cold-rolled mild-steel bodies with a powder-coated finish. Every compartment is fitted with a Type A cam lock as standard.

Should I choose a flat top or a sloping top?

Flat tops allow stacking or a shelf above the bank. Sloping tops keep the top of a public bank clear of litter and dust.

Where do 4 door lockers work best?

A 4 door locker serves four users from one footprint, which suits busy changing rooms, schools and shift workplaces where wall space is at a premium but everyone still needs a dedicated compartment.

What 4 door options are available?

Standard imperial, perforated metric, Vision Panel metric and a PowerBox charging locker, in standard 300 mm and wide-format (380-450 mm) widths. There is no 4 door in the standard metric range.
