To create matching bends in both 1/2" and 1" IMC using a mechanical bender, what should you do?

Using the 1" shoe for both the 1/2" and 1" conduit does not accommodate the differences in diameter and bending requirements between the two sizes effectively. Each conduit size requires a specific shoe that matches the conduit diameter for proper bending angles and maintaining consistency throughout the bends.

The correct practice entails using different shoes that are designed to match each specific conduit size, ensuring that the bends are uniform and meet the needed specifications for both conduit sizes. Each shoe is calibrated to provide the correct radius and angle for bends, which prevents deformation or incorrect angles, ensuring that the conduit fits securely in its intended application.

In this context, the best approach would be to use the 1/2" shoe for the 1/2" conduit and the 1" shoe for the 1" conduit, facilitating precise and matching bends in both conduits. This practice adheres to manufacturing standards and ensures safety and functionality in installations.
