Parts Desk Insights
Best Use Case: Use when you need a sealed cable pass-through for a .625" connector opening but would rather not disturb an existing factory-installed connector.
Common Issues: If installation doesn’t hold water, the most common cause is an improper seal—double-check that the cable and connector sit correctly in the clam opening and that the mounting screws are tightened evenly. Also confirm you selected the correct CableClam size for the connector opening.
