From documents to pharmaceuticals these 45L Rapid Range Security Crates are what is needed when it comes to storage or transportation. The crate is tamper evident using a simple pin system that has to be broken when reopening. You can also use the unit without the pin with a simple cable tie to lock the lid doors. The product nesting together after use also saves on room and gives freight savings when transported back to a depot. Polypropylene is known for its rigidity and strength and that is why this product is manufactured in this material. It gives the best performance under the riggers of warehousing and transportation. At IFP Group there are many product offerings around Security Containment so feel free to contact us for more information.
