We invite you to take a peak at some of the points below, and learn how our product stacks up against what you’re currently renting!

When you fill a storage container with your valuable items, the last thing you want to see when you close the doors is light escaping from around the doors!  If light can get through, you can bet than so can water, bugs, and critters.   Do you want your valuable items to share a storage container with a hungry family of mice, looking for a nice place to bed down for the winter?  (neither do we).

Our Storage Containers are purpose built to have all 4 edges of each door create a nearly air-tight seal (as per ISO 1496-1 Standard).

This standard was written for the sole purpose of building cargo containers that could withstand the rigors of being loaded & unloaded onto cargo ships, trains and trucks, fully loaded with 10’s of thousands of pounds of cargo without leaking, or allowing critters to enter and potentially destroy valuable cargo!

They are built to be able to be stacked 9 units high, fully-loaded (over 75 ft tall!) and be transported across oceans, through storms, getting pounded by highly corrosive salt water, wind, rain, snow, and STILL arrive at it’s destination, dry, sealed, and secure.

Isn’t this the type of box that you want to store YOUR valuables inside of?
