    Screw Clamp Terminal Blocks

    A powerful contact connection.

    Screw clamp terminal blocks provide a secure and efficient connection. Made of anti-corrosive steel, the screw clamp mechanism not only provides an extra layer of safety but it also creates a reliable connection thanks to the high contact pressure between the conductor and conductor strip. These terminal blocks are some of the most widely used and are an integral part of control panels across North America.

    For a connection you can count on.

    As one of the most popular types of terminal blocks around, screw clamp terminal blocks are built with an anti-release system, keeping them securely in place. These terminal blocks come in a variety of colors, configurations and mounting options, and they can also come in pre-assembled blocks that can be easily mounted to DIN rail. Found across a number of applications in railways as well as industrial, commercial, and marine sectors, screw clamp terminal blocks are designed to handle the heavy demands of some of the toughest jobs.
