Clear Plastic Cover Enclosures

Polycase offers several electrical enclosures made from polycarbonate with a transparent clear cover for those applications that need visual access to internal components. Clear and transparent waterproof boxes protect components in harsh conditions and are available in a variety of sizes and styles. Molded from durable, UV-stable material, polycarbonate enclosures with clear lids can be trusted to keep your components safe. These enclosures are designed for outdoor use as they are waterproof and UV-resistant, meeting NEMA and IP ratings for wet and dirty environments.

Why Use Clear Plastic Cover Enclosures?

A transparent cover can be a useful feature on many different types of enclosures and in many different applications. Typically, the purpose of a clear junction box is to make it easy to visually inspect the enclosure’s components without the need to actually open the enclosure. This can be critical in applications where opening your weatherproof box enclosure could mean exposing your components to the conditions you’re trying to guard against in the first place.

Industrial control panels, circuit breakers, utility meters, communications devices and many other applications can benefit from the use of a transparent plastic enclosure. These devices often require regular status checks, but they also need to be protected from environmental hazards, making transparent enclosures an excellent solution. Even simple DIY electronic project boxes, however, can sometimes benefit from the convenience of a transparent cover in certain applications.

Polycarbonate plastic is the preferred material for clear cover enclosures because polycarbonate is easy to manufacture in a transparent format while keeping a high standard of durability. Transparent Cover Enclosures from Polycase

Polycase’s boxes are designed to offer a higher standard of toughness, thanks to their durable polycarbonate construction, along with features like weatherproof silicone gaskets and stainless steel fasteners to create incredibly durable enclosures. Many of our models also carry protective ratings such as NEMA 4X and IP66, offering professional-level protection that guards your most sensitive devices against harsh environmental conditions.

It’s also incredibly simple to customize your clear waterproof junction box through Polycase. Using our in-house CNC machining and digital printing equipment, we can customize most stock enclosure models with connector cutouts, high quality digital imagery and more — all with lead times as short as one week. What’s more, Polycase offers a complete selection of cable glands and other enclosure accessories to ensure that your enclosure maintains its dustproof and waterproof protective ratings.
