Frequently asked questions

Do you offer other eurorack side brackets then 1U, 3U, 4U and 6U?

No, we manufacture side brackets in sizes: 1U (Intellijel and Pulp Logic), 3U, 4U (3U+1U Intellijel and Pulp Logic), and 6U. These sizes allow for the construction of Eurorack cases of any size.

Manufacturing longer side brackets doesn't make sense from a cost perspective. Low demand results in smaller manufacturing batches with much higher pricing, and producing large batches would lead to extended and costly storage periods. In the end, this would make a 9U bracket made from a single piece more expensive than using 3x3U brackets – which would be confusing for our customers.

We have decided to stick with the sizes we currently offer because they allow for the construction of any Eurorack case, regardless of shape or configuration.
