Double your Storage Capacity with our Topper Solution

Pentalver presents an innovative container conversion created for the self-storage industry, the “Topper” unit. Designed to sit on top of your current 20ft units and available in two different configurations to offer maximum flexibility.

The 20ft Topper units come as standard in either a double 8ft storage space configuration with a 4ft walkway in between; or a single 15ft storage unit with a 5ft walkway at the end of the container.

Both options feature steel vandal-resistant personnel doors and are offered in gentian blue (RAL 5010), cobalt blue (RAL 5013) and bottle green (RAL 6007) as standard. Bespoke configuration options and colours are available.

We can also provide a standard 13-thread straight-flight staircase with various landing options to access the units.
