What size do you really need?

With indEx, custom comes as standard!
Contact us to discuss your requirements.

Below is a small range of enclosures which we entitle as “standard”. The enclosure industry, especially for Ex enclosures, has been producing a tiny range of between 10-20 standard sized enclosures (roughly based on the sizes below) for many years.

This makes it very easy for them to churn out the same thing time after time. So you would think they would be perfect by now — but we all know that is not true. However, it is something which the Ex industry and you the customer, has become accustomed to, but it is only because there has literally been no other option!

We only put them in to show we can offer these sizes but that is the only reason.

indEx are best known for our ability to custom build any size rapidly, with any footprint of any other manufacturer, assembler or distributor; or just one you make up yourself!

So remember: The sizes below are just an indication. You tell us what size you want!
