Every centimetre counts. When is a 250 mm locker the only right choice?

In an ideal world, every school corridor and employee changing room would have unlimited space. In reality, however, walls often dictate the conditions, and you must fit lockers where space is tight.

At Malow, we believe that a lack of space should not mean sacrificing quality. That is why our engineers created the MSUM 2520 and MSUS 2552 series – compact metal lockers with a single module width of 250 mm.

Why choose the 250 mm series?

• These models were created to offer real functionality. It is a solution for those who do not accept half-measures like wobbly, bolt-together furniture from imports or supermarkets.
• Robust construction: Despite its compact size, it is still a fully welded steel body. Its rigidity and stability are identical to our largest models.
• The master of compactness (MSUM 2520): Ideal for construction containers. It maximizes storage space while occupying minimum room.
• Option for schools (MSUS 2552): Thanks to its depth reduced to 400 mm, it allows meeting strict fire safety standards in narrow corridors without blocking escape routes. The single module width of 250 mm allows fitting more lockers in a small cloakroom.

The Myth of lower price: Why smaller is not always cheaper

We must be honest – a smaller size does not always mean a lower price. The technological processes (cutting, welding, painting) are just as labor-intensive as for standard dimensions. By choosing 250 mm models, you are investing in the ability to manage difficult space.

• Complexity of the process: The final cost of the locker consists of advanced operations: precise cutting, bending, welding, and powder coating.
• Production time: The amount of work needed for these processes is similar, regardless of whether the locker is 250 mm or 300 mm wide.
• Investment in space: By choosing 250 mm lockers, you invest primarily in the unique ability to manage difficult space, not in reducing purchase costs.

Why Is the Standard WSU Better?

Before you decide on narrower models, check if you definitely cannot fit the standard WSU line. Why? Because it's not just a locker, it's a full set of benefits:

• Economy of scale: Thanks to serial, automated production, the WSU line offers the best price-quality ratio.
• Accessories on hand: For standard lockers, we have a ready range of accessories: benches, bases, and sloping tops.
• Time and convenience: In the case of 250 mm models, any accessories (like tops) must be made on special order, which increases waiting time and costs.

Quality where space is lacking

Investors managing facilities with limited areas often faced a difficult dilemma. They often had to choose budget, self-assembly products imported from China, which differed in quality from accepted standards. This involved a time-consuming assembly process and unsatisfactory structural stability.

Our compact models offer the functionality, durability, and rigidity known from standard lockers, but in a format adapted to micro-rooms. This is a proposal for those who are forced to save space but do not accept compromises regarding the furniture's lifespan. However, we emphasize: if premises conditions allow it, we always recommend choosing full-size WSU lockers. The difference in investment costs is small, while the difference in user comfort is significant.

MSUM 2520 – The specialist for construction containers

This model is the answer to the challenges of small social rooms. Unlike budget solutions, we provide a fully welded product, which guarantees stability despite such a narrow construction.

Technical specification:

• Dimensions (HxWxD): 1800 x 500 x 500 mm (two-column module).
• Width of one column: 250 mm - a compact dimension requiring conscious use.
• Construction: welded, made of steel sheet 0.6-0.8 mm thick, protected by zirconium conversion method and powder coated.
• Interior equipment: each compartment has a shelf, a plastic bar with two double hooks for clothes, and a self-adhesive mirror and an additional hook on the door as standard.
• Ventilation and identification: doors equipped with Malow type perforation ensuring air circulation and a self-adhesive name card holder.
• Security: cylindrical lock bolted at one point (two keys included).
• Colours: available in 16 coloUrs from the RAL palette without extra charges.

For whom? The MSUM 2520 locker is recommended primarily for employee containers and temporary construction facilities. It will be appreciated by investors who must meet social requirements in a limited area, without giving up the durability of metal furniture.

MSUS 2552 – Rescue for narrow school corridors

Designed for facilities struggling with strict fire regulations. A key feature is the reduced locker depth to 400 mm, which helps maintain the required width of the evacuation passage.

Technical specification:

• Dimensions (HxWxD): 1800 x 1250 x 400 mm (five-column module).
• Column width: 250 mm.
• Number of compartments in a column: 2
• Construction: welded, made of steel sheet 0.6-0.8 mm thick, protected by zirconium conversion method and powder coated.
• Interior equipment: each compartment has a plastic bar with two double hooks for outerwear or a backpack.
• Ventilation and identification: doors equipped with Malow type perforation ensuring air circulation and a self-adhesive name card holder.
• Security: cylindrical lock bolted at one point (two keys included).
• Colours: available in 16 coloUrs from the RAL palette without extra charges.

For whom? This model is dedicated to schools and educational institutions where the priority is maximum use of available corridor space without blocking the passage. It is a compromise solution – ideal for textbooks and lighter clothing, constituting a functional alternative where deeper and wider standard lockers cannot be installed due to a small amount of space.

Accessories

A professional changing room requires plinths, benches, bases, or sloping tops to facilitate cleaning. Here, another fundamental advantage of the WSU standard is revealed. Lockers with widths of 300 mm and 400 mm are a standardized system – you have immediate access to a full range of inexpensive, serial accessories. Do you want to place the locker on a bench? You choose a ready-made element from the catalog.

In the case of the MSUM and MSUS series (module width 250 mm), these are non-standard solutions. If you wish to equip these narrow lockers with tops or bases, it will be necessary to make them on special order. In practice, this means higher costs and longer waiting times.

Expert verdict: The key to a good decision

he recommendation for the investor comes down to one simple rule:

• Do you have space available? Without hesitation, choose the proven WSU standard. It is the undisputed leader in ergonomics and economy. By choosing it, you gain not only a larger locker but also access to an entire ecosystem of inexpensive, compatible accessories (benches, plinths, tops) that are available immediately. It is the optimal choice in every respect.
• Is space limited? Reach for MSUM or MSUS models. These are solutions for special tasks. You will pay a similar price for a narrower product, but in return, you receive a welded, stable structure that will save the functionality of the changing room where no other solution would simply fit.
