Using the iTOOLco CR10 Curb Roller is straightforward. First, if you need to guide the wire into a manhole, use the carved - out part to hang the roller on the top of the manhole. You can also mount it using the 4 mounting holes. The carved - out area can fit a 2 - foot rigid pipe for alternative mounting. It works great with iTOOLco Real Jacks. When using it around sharp corners, just place it appropriately to guide the wire smoothly. As for maintenance, keep it clean from dirt and debris. Regularly check the rollers for smooth rotation. If there are any signs of wear, you can contact iTOOLco's support as it comes with a 6 - year warranty.
