Waterproof Micro Cases

Business supplier of smaller sized waterproof equipment cases

As one of the smallest waterproof cases ranges available (in terms of dimensions rather than options) – and being the main rival to the Peli Micro range – SKB 3S Series cases are a great option for smaller products and equipment. They can also be used within larger cases as part of a “kit”.

The compact sizes and watertight design are also combined with a durable exterior and a range of bright colours.

Please see below for the options available in the SKB 3S Series range.

More Info on SKB 3S Series

Smaller cases with big performance

SKB 3S Series cases should be one of the main options you consider (alongside Peli Micro) if you require a small protective case.

Available in a range of compact sizes (with 10 different options in total), the 3S Series can also be purchased in 3 colours (black, orange, and yellow).

Besides the small dimensions, 3S Series cases are also completely watertight. This versatility and performance level makes them suited for use around water, or if the contents would suffer serious damage from getting wet.

SKB 3S Series are also incredibly tough. The cases have achieved the MIL-STD-810F certification (undergoing Transit Drop Test / Immersion Test), and are also dust tight too (SAE J575 certification)

All of this makes these cases ideal for a range of applications, including protection for video / camera equipment, tablets, first-aid supplies, eyewear and any small sized tools or items. They are also frequently used as part of larger collections of tools and equipment (i.e. housing specific items or components) which are then place in a larger outer transit case.

Custom SKB 3S Series Cases

SKB 3S Series, despite their smaller sizes, can still be customised in a number of ways.

For example, the smooth outer surfaces are ideal for adding screen and / or digitally printed branding, or even vinyl graphics.

Perhaps most crucially however, is the inclusion of custom foam inserts.

Manufactured from Plastazote, these inserts can provide levels of cushioning protection for your products or components and can also have the recesses cut to the exact shape of your items too.

SKB 3S Series FAQs

Common questions regarding SKB 3S cases

Have questions regarding the SKB 3S Series case options? Or indeed any of the wider range of SKB cases?

Whilst the the below section covers the more frequently asked questions regarding these cases, should you require any further information then please get in touch.

What size SKB 3S Series cases are available?

The 3S Series cases are available in a range of 10 sizes. The smallest of these is 100 x 60 x 24 mm, with the largest being 303 x 229 x 152 (please note these sizes reference the internal dimensions of the cases).

What colour 3S Series cases can I choose from?

SKB 3S Series cases are available in 3 colours as standard – black, orange, and yellow. The AC100R option is available in red with a “dive strip” to make it suitable for scuba diving applications.

Are 3S Series cases waterproof?

3S Series cases are watertight, having undergone the MIL-STD-810F immersion test (which also covers transit drop test). They are also dust tight, having been tested to SAE J575.

Do SKB 3S cases have a guarantee?

SKB Cases come with the standard lifetime warranty supplied by SKB. However, please note that the case contents themselves are not warranted. As such, it is recommended that cases should be tested prior to submersion.

Are there any similar waterproof cases?

Due to their very small dimensions, there are not a huge amount of alternative waterproof cases of this size. The main competitor would be the Peli Micro and Peli Ruck options, which offer similar dimensions and levels of performance.
