Selecting the correct roller is critical for a safe and successful installation. To make the best choice, consider these factors:

1. Project Type: Determine if you are pulling in a straight trench, around corners, or through manholes. This will tell you the type of roller you need (trench, corner, or manhole roller).

2. Cable Diameter and Weight: Select a roller with a Working Load Limit (WLL) that can safely support your cable's weight and a sheave diameter that can accommodate the cable size without exceeding its minimum bending radius.

3. Material: Rollers are typically made of steel, aluminum, or nylon. Steel rollers are highly durable for heavy-duty applications. Nylon rollers are often used for delicate or lighter cables, as they are non-conductive and prevent sparking.

4. Placement: Proper roller placement is just as important as the type of roller. Rollers should be spaced at regular intervals along the route to provide continuous support and minimize friction.
