• Measure and Cut the Hole: Accurately measure the diameter of the wire or cable and cut a hole slightly smaller in the panel or surface where the grommet will be placed.
• Prepare the Grommet: Ensure the rubber grommet is clean and free from any debris. If necessary, lightly lubricate with a silicone-based product for easier installation.
• Insert the Grommet: Gently press the grommet into the hole, starting from one side and working your way around. It should fit snugly without excessive force.
• Thread the Cable or Wire: Once the grommet is securely in place, thread the cable or wire through it. The grommet should provide a protective, snug fit around the cable.
• Final Check: Ensure the grommet is seated properly and provides a tight seal. Adjust if necessary to avoid any movement or chafing of the wires.
