We are delighted to reveal that the US Patent and Trademark Office has awarded Larson Packaging Company a patent for our Interchangeable Cartridge System for toolless rack crates. It’s a remarkable milestone that we think highlights our commitment to developing innovative packaging solutions that address real-world operational and logistical challenges.
The Interchangeable Cartridge System (ICS) delivers exceptional versatility to rack crate shippers.
Rather than holding a number of separate crates to transport servers of different sizes and weights, ICS lets you have one, single crate and floater base, then adapt that with various cartridge configurations that are built to carry a server of a specific weight or dimensions.
This modular character means that ICS is capable of accommodating any number of shipping requirements. Yet it sacrifices neither protection nor performance — and even improves cost-effectiveness.

Ease of use is central to the design
Users can swap cartridges out quickly — without tools — streamlining changeover processes and reducing handling time.
To further enhance efficiency, each cartridge features distinct color-coding and clear labeling that corresponds to specific equipment. This minimizes the risk of configuration errors and ensures your team selects the right setup for the right server rack every time.
Benefits spread across your entire supply chain.
Vast flexibility: your core advantage.
The possibility of rapid reconfiguration eliminates the burden of managing multiple specialized crates for different setups.
Warehouse optimization: save space reduce complexity.
The need to store multiple crate configurations simply evaporates — freeing up floor space and simplifying your inventory management.
Cost savings: make crates last longer.
Adaptability translates into measurable and substantial cost savings. A modest additional investment (1.5 times normal) cuts overall procurement costs because it extends the life of one rack crate to at least five, and up to 10, separate uses. That’s, potentially, over a sixfold boost to ROI.
Better sustainability: control your environmental footprint.
Extending usable crate life reduces waste. In addition, we prioritize end-of-life recyclability by reducing screws and nails and engineering modular base and cap components that separate effortlessly so materials can be recovered and processed efficiently.
This patent award validates our belief that the best innovations solve multiple problems simultaneously—improving efficiency, reducing costs, and protecting our environment.
