    SKB cases are recognised within the market as being one of the most popular waterproof cases available today.

    Predominantly used as dust and waterproof cases, SKB cases are suitable for an unlimited range of uses and are the ideal choice if you have delicate or expensive equipment that needs to be kept safe.

    03: SKB Case Features.

    Equipment cases that also offer exceptional usability

    The SKB range is recognised within the market as a hardwearing, high-quality solution for any application.

    Carefully engineered by an experienced team, SKB cases provide uncompromising quality and extremely high levels of protection ensuring that they are waterproof and resistant to impact, shock and dust.

    This attention to detail is also reflected in the handle, catch and hinge designs, all of which have been created to be not only durable and long-lasting, but also to be incredibly easy to use as well.

    There are also a number of specialist case types in the range, including those suitable for musical instruments, sports equipment, fire-arms and even drones!

    Besides this, SKB has built up a reputation as being one of the best waterproof case manufacturers on the market whilst demonstrating exceptional protection in any situation.

    04: Custom SKB Case Options.

    Custom foam inserts, electronics bezel kits, branding and more

    SKB cases offer a number of potential customisation options straight out of the box.

    This includes bezel kits for mounting electronics within the case, shoulder straps on smaller cases, divider sets and cubed foam inserts (whereby you can easily modify the foam yourself).

    However, a key benefit of working with GWP Protective is that you can source custom foam inserts for SKB cases that are tailored specifically to your product, and can also provide a very specific (calcultaed) level of cushioning protection during transit.

    From an aesthetic point of view, it is possible of course to select from the different standard case colours available, but also a completely bespoke hue if your order volume is high enough.

    Your foam inserts can also be tailored to match your brand colours, and aid with tool / product identification.

    Laser etching on the foam can also add logos and instructions, whilst the cases exterior can be enhanced with screen or digital printing, or labelling (including vinyl wraps) as a cheaper option.

    07: GWP Protective.

    More than just a waterproof case supplier

    Any company could sell you a waterproof case. So why get yours from GWP Protective?

    Well, there are a number of compelling reasons.

    First of these is that GWP has been in business for over 25 years. In this time we have helped literally thousands of companies just like yours in sourcing the most suitable protective case for their application, product or industry.

    Further to this, being an independent company means that we can offer you a wider range of cases than you can find elsewhere, and can give honest, impartial (and free) advice on the best option for your specific requirement.s

    Waterproof case with foam
    Waterproof cases with foam offer not only protection from water, but from shock, impact and mishandling too.

    Perhaps even more important than this though, is the you having the ability to source case and foam inserts from a single supplier.

    But why is this important?

    Crucially, it means the fit and compatibility between case and foam is greatly improved compared with sourcing them separately. Buying together also reduces costs, minimises admin and lowers lead times.

    Add this to an experienced design team, services such as just in time supply and a dedicated customer support team, and the choice of where to get your cases from seems obvious…
