These single-row terminal blocks connect the same number of circuits as double-row blocks, but in a narrower footprint. Also known as barrier terminal strips, they have dividers to separate live wires and keep your setup tidy. Mount them directly onto control panels, enclosures, and equipment.

You can screw down your stripped wire directly or attach a terminal to prevent damage from the screw. Ring, spade, and hook terminals fit around the screw and hang on tightly, even in high-vibration setups. Pin terminals, blade terminals, and wire ferrules are easier to slip under the screw head, but they don't stay put as well as other terminals when vibrated or pulled.

Note: Stick the included insulation strip to the bottom of the block before installing. The voltage listed applies only when the strip is attached.
