What is the type of fitting commonly used for supporting exposed conduit?

The fitting that is commonly used for supporting exposed conduit is a conduit strap or clamp. These fittings are specifically designed to hold the conduit securely in place, preventing movement and ensuring that it remains aligned properly. Conduit straps or clamps come in various sizes to accommodate different conduit diameters and are essential for maintaining the physical integrity of conduit runs in electrical installations.

Using conduit straps or clamps is crucial because they provide the necessary support to prevent sagging or bending of the conduit over time, which can lead to damage or unsafe conditions. Additionally, they help in complying with electrical codes and regulations that dictate how conduits must be installed for safety and functionality.

Other options, while related to conduit systems, serve different purposes. A condulet is a type of fitting that provides wiring junction points and does not primarily support conduit. Connectors are used to join two sections of conduit together but do not serve to support the conduit itself. Lock nuts and bushings are designed to secure conduit at junction boxes or enclosures but are not meant for supporting exposed conduit along its length.
