Parts Desk Insights

Best Use Case: Use these cushion clamps to help hold marine wiring securely while adding an insulating, vibration-dampening cushioned interface between the cable and mounting surface.

Common Issues: If clamps feel loose or don’t seat correctly, confirm the cable diameter and that the cushion clamp size matches (5/16"). Also inspect the mounting surface and related hardware/fasteners to ensure a secure fit and proper wire strain relief.
