    Angled Bracket

    Mount terminal blocks, power supplies, relays, and other control and distribution devices on walls and other flat surfaces and in enclosures.
    DIN Rails with Bracket—DIN rails with a bracket create extra space behind them to accommodate bulky items.
    DIN Rails with Angled Bracket—DIN rails with an angled bracket are tilted, letting you fit more of them into a vertical space. For easy access, position high-mounted devices so they’re tilted downwards and low-mounted devices so they’re tilted upwards.
    DIN Rails with Centerline—On DIN rails without mounting holes, drill holes where you need them. Rails with a centerline guide where you should drill.
    DIN 3—DIN 3 is the most commonly used rail.

    Magnetic-Back DIN Rails

    Image of Attribute. Front orientation. Contains Annotated. DIN Rails. Magnetic-Back DIN Rails.
    Mount and reposition components without drilling leaky holes in your steel enclosure—a strong magnet holds these DIN rails in place. Since they install without screws, they fit in spaces that are too small for a screwdriver.
    UL 94 V-0—DIN rails meet UL 94 V-0, so if they catch fire, they’ll self-extinguish within 10 seconds and won’t spread the fire by dripping.

    Customize component placement without drilling leaky holes—these channels screw into the mounting bosses in your enclosure. Use strut channel nuts (sold separately) to add a DIN rail at any point along the channel, then clip on terminal blocks and other parts. To adjust spacing, loosen the strut channel nuts and slide the rail along the channel.
