This is a modular vault system built on-site with lightweight, easily-connectable corner pieces and scalable sidewall lengths that are configurable to your specifications and can be completely installed in just one day.


We focus on the details that accelerate construction so you can focus on the things that elevate our world.

STAKKAbox™ ULTIMA Connect offers long-lasting installed life. The offset joints improve sidewall strength to develop the load rating needed.
