DIN Rail Kits

We offer 35mm steel DIN rail kits made specifically to fit the HP Series, ML Series, SG Series, SK Series, WH Series, WQ Series and ZH/ZQ Series DIN rail enclosures. Our 35mm DIN rail mounting kits include screws and washers for assembly. DIN rails allow for easy installation of terminal blocks and other devices within Polycase electrical enclosures.

View our Enclosure + DIN rail kit cross-reference guide here.

A DIN rail is a metal rail with a standardized size and design that makes it simple to mount certain types of equipment inside an electrical enclosure. Using a compatible set of screws, simply attach the rail to the enclosure’s internal mounting bosses for a secure fit. Once the rail is attached, you’ll have an easy place to mount any kind of electrical component that’s designed with DIN rail mounting hardware. Typically, such components include:

  • Terminal blocks
  • Programmable logic and automation controllers
  • Circuit breakers
  • Power supplies
  • Motor controllers
  • Antennas and WiFi routers
  • Ethernet, phone and fiber optic patch panels

These aren’t the only types of equipment that can use DIN rails. Many other components offer DIN rail mounting options, and some that aren’t originally designed for DIN rail compatibility can be mounted using DIN rail adapters. 

Why Use a DIN Rail Mounting Kit from Polycase?

Our DIN rail kits offer a ready-made solution for mounting equipment in your enclosures. Here’s why our customers choose DIN rail solutions from Polycase:

  • Perfect Fit: Each Polycase DIN rail kit is designed specifically to fit one or more enclosure models, so it fits right out of the box with no need to cut or modify. Mounting slots are pre-cut into the steel rail, making it simple to line up and attach your rail to your enclosure’s mounting bosses.
  • Durable Materials: Our DIN rail kits are made from heavy-duty steel with a zinc-plated finish to ensure long life and durable performance. 
  • Top Hat Design: Although DIN rails come in several different shapes, the 35mm “top hat rail” design used in Polycase’s DIN rail kits is by far the most popular and compatible with the widest variety of devices. Check your equipment’s DIN rail mounting brackets and note which type of DIN rail they’re designed for.
  • All-In-One: No need to hunt for the right mounting components. We’ve taken care of everything. Every Polycase DIN rail kit includes all of the components you need to mount the rail in your enclosure, including screws, washers and the custom-cut rail itself. 

Browse all of our DIN rail options on this page and find the perfect fit for mounting your components. If you’re ready for checkout with your enclosure order, don’t forget that we also offer a lineup of enclosure accessories to create your ideal protective solution!
