Identify Your Business’ Micro Case

Full size guide covering the SKB 3S Series range of cases

With 10 size options in total (and being comparable to Peli Micro cases in terms of range), the SKB 3S Series is a great option if you need any smaller cases.

To help with your decision-making process, not only does the below SKB 3S Series size table allow you to compare and contrast the various options, but it also details a number of other important buying info too. This includes the specific colours, weights etc.

This in turn should allow you to make an informed decision on which SKB case would be the best option for use at your company.

If you are still not able to find the info or details you need however, one of GWPs friendly and knowledgeable advisers will be happy to help.

Tips on using the SKB 3S Series Case Size Table

Even with a case collection such as the SKB 3S series – which contains a relatively small number of sizes – it can still be difficult to locate the specific information you need. Obviously having all of the data in a table can help considerably with this, as does the diagram that you can see alongside this text. This highlights how the cases are measured, and how this relates to the data in the table.

However, should you still require assistance we’ll be happy to help. You can reach a GWP advisor on 01722 416 440 or email
