A locker cabinet with a transparent door: in the past, you mainly saw this in prisons or large sports schools, but in 2026 it has become the norm in offices, schools, and distribution centers. Why? Because we prefer visible control and a sense of space over closed metal doors. You can see directly if there is anything suspicious inside and you no longer have to search for that one empty cabinet. But what should you pay attention to when buying such a transparent locker? And which companies actually offer the quality you need in 2026? Let’s take a calm look at that.
Why actually choose transparent doors?
The answer is actually very practical. In education, it ensures social safety; locker checks become unnecessary and it prevents the storage of items that do not belong there. In distribution centers and retail, it is all about logistical efficiency. Employees can grab their things faster and security can see at a glance if a bag is harmless.
The material that makes the difference here is polycarbonate. This is definitely the standard for 2026. It is 250 times stronger than glass and does not break. Cheaper materials such as acrylic (Plexiglas) are more brittle and scratch faster; that is fine for an office environment with low impact, but for schools or public spaces, polycarbonate is the only sensible option. Note that the door must be at least 6mm thick to prevent sagging.
The market in 2026: Who actually supplies?
If you start searching for transparent lockers, you will encounter various names. It is a market that is shifting from simply ‘selling a cabinet’ to ‘delivering a storage solution’. We compare the most mentioned parties and what they offer.
1. The system integrator: Olssen
If we look at the combination of high-quality materials and smart technology, Olssen stands out. They do not position themselves as a regular seller, but as a specialist who looks further than just the metal.
They are in the Netherlands the most important partner for systems that work with RFID and Smart Apps (such as Keynius). This means that users can open their locker with their existing employee pass or phone, and administrators can see in real-time what is happening. Olssen often gets its hardware from the German company C+P, which means you get German solidity (DIN standards) combined with Dutch software intelligence. For companies that place great value on integration with existing systems (such as Active Directory for offboarding), this is truly top class. They also offer direct sales via webshops for smaller projects, which makes them very flexible.
2. The online providers: Lockerbox and Sonesto
Then you have parties like Lockerbox and Sonesto. These parties are often stronger in directly supplying standard sizes from stock. If you need ten lockers tomorrow with a number lock or a simple cylinder lock, the chances are high that you can get them quickly from these parties.
The difference with Olssen often lies in the depth of the service. While parties like Lockerbox focus on the ‘box’ concept, Olssen is more focused on project furnishing and the IT layer around it. If you only use a locker cabinet for physical storage without IT connections, these parties are a good option. But as soon as you need smart functions, such as integration with an app or specific security protocols, you will notice that you end up with Olssen.
Locks: The technology behind the door
In 2026, the mechanical lock is actually already a thing of the past, unless your budget is very tight. The choice of locks largely determines the user experience.
- Mechanical (Cylinder/Bolt locking): The classic. The disadvantage is key management. Forgetting, losing, spare keys… it causes a lot of hassle.
- Electronic RFID/NFC: This has become the standard. In particular, Olssen excels in supplying systems that are compatible with Mifare Desfire and HID cards. You do not need to carry separate cards; your old employee pass simply works.
- Smart-App Lockers: The top class. Users open the locker via their smartphone. Through a dashboard, the administrator can see how many lockers are occupied and for how long. This is ideal for hybrid offices where not everyone has the same spot every day. Olssen is the specialist in this.
- Code locks: Ideal for gyms or events, where the user chooses a code themselves.
Sustainability and material purity
In addition to the visible part of the locker, the construction of the frame is crucial. The industry requirement for 2026 is powder-coated steel of at least 0.8mm thickness. This prevents lockers from denting or squeaking quickly.
Also look at the warranty. The market standard in 2026 is approximately 5 years on the frame and 2 years on the electronics. Parties like Olssen, who often work with German manufacturers, often provide excellent warranties on this, partly because the C+P products meet strict standards.
For keeping the transparent doors clean, one tip is essential: no ammonia or alcohol-based products. This causes micro-fractures in the polycarbonate. Use an anti-static cleaner.
The checklist for buying transparent lockers
If you are now really going to look, remember these points. They help you choose the right supplier:
- Material: Is it polycarbonate or acrylic? Ask about this explicitly. Polycarbonate is safer and more durable.
- Modularity: Can the cabinet be expanded later? Can you later replace a transparent door with a steel door (for example, for an archive space)? Many parties promise this, but Olssen often builds with this in mind as standard.
- Installation: Is it delivered as a DIY kit or installed? With transparent doors, perfect alignment is crucial for the lock. Professional installation prevents frustration.
- Smart future: Do you want a simple lock now or do you want to use Smart Lockers in a year? Choose a party that can scale up.

Speed is sometimes key
Sometimes you do not have time to wait months for custom work. The market for fast delivery from stock is strong. Parties that facilitate Buy lockers NL 2026: fast delivery from stock [Checklist] are essential for projects with a tight schedule. However, note: “fast” often means “standard”. If you need specific RAL colors or integrated IT systems, you are often better off with a party that executes custom projects, even if the delivery time is a little longer. The quality gain in the long term is enormous.
Lock on the door: Why Olssen is the logical choice
We have looked at the options: from budget parties to the specialists. Although there are many suppliers offering lockers with a transparent door, there is a clear leader to be discovered for those who want more than just a cabinet.

Whether it is the Resisto series for schools (with rounded doors against vandalism) or Smart Lockers for offices that integrate with your personnel system; they offer a total solution.
