Urgent Update 27.10.2020: Partial shipping delays

Health & Safety:

Due to the ongoing pandemic we have moved our staff to 50% home office, so we only work in shifts in the local office. This ensures our internal processes are not affected. With compulsory masks throughout the office building and weekly in-house testing for Covid-19, we hope to keep the virus away as much as possible.

Availability of goods:

As a result of the pandemic, we unfortunately have to inform you that some orders cannot be fulfilled on time.

Reasons for this are, supply bottlenecks in the manufacturing countries, Covid-19 cases at our suppliers as well as their limited capacities, which cause additional delay. Container shipping is currently also only possible to a limited extent. This means that journeys in the entire global network can be cancelled or can only be carried out with delays, causing further delays in delivery. Nevertheless, we do everything in our power to deliver the goods to you as quickly as possible.

Delayed delivery of Sammitr Hardtops:

Unfortunately, our manufacturer Sammitr is currently experiencing major delays in delivery. The manufacturer is currently undergoing a pandemic-related restructuring process, which unfortunately also directly affects deliveries to Europe. This may result in significantly longer delivery times. All customers who are affected by delivery delays will of course be informed immediately.

We apologise for any inconvenience caused.


Ullstein Concepts GmbH presents:

Light modular storage solutions for light commercial vehicles... powered by GEMA

Preconfigured modular solutions

The preconfigured modular solutions powered by GEMA are available for all common pickups and light commercial vehicles, e.g: Mercedes-Benz Sprinter, Volkswagen Amarok, Caddy, Crafter Transporter or Ford Transit.

In addition to the preconfigured systems, all modules can be ordered and combined individually.

Special solutions

With GEMA aluminium lightweight construction modules, Ullstein Concepts offers new solutions for the individual modification of your commercial vehicle. With its light and highly stable construction, we meet all requirements! Industry-specific modules enable perfect load compartment design.



From product development to the manufacturing process, the manufacturer "GEMA®" respects the environment and components are 100% recyclable as far as possible.

The aluminium profiles developed by Gema offer outstanding stability, are anodized and therefore corrosion resistant.


The module components are attached to the vehicle using a longitudinal anchoring rod, which makes it possible to distribute the tensions over the entire length of the rod rather than over the individual anchors.

The shelf anchoring system has been designed ergonomically and sturdily to ensure safe use. Only high-quality materials such as stainless steel and aluminium are used in the production process. Particular attention was also paid to the geometry, which is carefully rounded and free of sharp edges.


Our rack system offers a wide range of possibilities and combinations for individual customization depending on the vehicle and the task at hand.


Due to the lightweight aluminium construction, fuel and maintenance costs are low and the loading capacity is increased. This also leads to lower CO2 emissions.


The use of Gema's specially developed aluminium profiles makes the shelves very robust, ensuring stable, safe and resistant load securing.

Capacity per side 350 kg
Drawer capacity 90 kg
Shelf capacity 120 kg


Thanks to the use of composite plastics that do not make any noise.
