Aluminum, Plastic & Steel Panels

We offer internal mounting panel kits for a variety of different enclosure series. Our enclosure panels are made from aluminum, steel or durable plastics like ABS and polycarbonate, with a variety of features and included hardware. Polycase can even customize your internal panel with cutouts to help accommodate components.

Below, we’ve got more information on how enclosure panels work and why they’re common in many different types of electrical equipment.

Why Use an Enclosure Panel?

In many cases, mounting electrical components directly onto an electrical enclosure isn’t a workable solution. For one thing, installation and cable management can be more challenging when components and connectors have to be fit directly into the box. Moreover, modifying the enclosure body with mounting holes can allow the ingress of water and dust, potentially compromising an enclosure’s NEMA and/or IP rating.

A removable back panel provides a safer and easier way to mount components inside an enclosure. Simply attach your components and modules to the panel and then mount it inside the enclosure using the included hardware. So long as you’re using a compatible enclosure model, you’ll be able to mount your panel quickly and easily, typically with minimal need for modifications.

Enclosure panels are widely used across industries, particularly in applications that use wall-mount enclosures. These often include junction boxes, automation control panels, power supplies and a huge variety of others. Thanks to the simplicity and versatility of enclosure panels, they’re able to fill these numerous different roles while remaining cost-effective and easy to work with.

Polycase Enclosure Panels

Polycase’s selection of enclosure accessories includes a variety of heavy-duty enclosure panels. We design these panels to attach seamlessly to the mounting bosses built into many of our most popular enclosures. Simply choose your enclosure series on the sidebar, and you’ll see panel kit options made specifically for out-of-the-box compatibility.

Some of our panels offer additional features and configurations. These can include anything from multiple mounting position options to a swing-out functionality that provides easy access to the panel and its components. Other panels are available with different material options, such as steel or ABS plastic, to meet the unique needs of your application.
