Mount terminal blocks, power supplies, relays, and other control and distribution devices on walls and other flat surfaces and in enclosures. DIN 3 is the most commonly used rail.

Rails with a bracket create extra space behind them to accommodate bulky items. 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.
