Blue Sea Systems 1003 is a marine CableClam deck-seal fitting used to pass electrical cables through decks, bulkheads, or panels while helping maintain a watertight seal. It is commonly used for antenna cables, solar wiring, electronics wiring, lighting cables, and other marine cable-routing jobs where the cable end or connector needs to remain intact.
Key Features
- Blue Sea Systems marine CableClam
- Part number: 1003
- Watertight cable pass-through fitting
- Allows cable routing without removing factory cable ends
- Suitable for deck, cabin, console, and bulkhead cable runs
- Designed for marine electrical installations
Application Compatibility
Used for marine cable-entry installations where a watertight pass-through is required. Confirm cable diameter, connector size, and mounting surface clearance before ordering.
Fitment Notice
Match the CableClam size to the cable and connector being passed through. The opening must be large enough for the connector, while the seal must properly compress around the cable jacket.
When This Product Needs Replacement
Replace if the seal is cracked, compressed, leaking, UV-damaged, or if the fitting no longer seals tightly around the cable.
Installation Notes
Drill and seal the mounting surface carefully. Use marine sealant where appropriate, avoid sharp cable bends, and confirm the cable is supported so the seal is not carrying strain.

Parts Desk Insight
CableClams are best chosen by connector size first, then cable diameter. That prevents the common issue where the cable fits the seal, but the connector will not pass through the fitting.
