Blue Sea Systems CableClam with Stainless Steel Dress Cap 1.40in

The Blue Sea Systems CableClam is a watertight cable entry fitting for routing a cable — complete with its connector already attached — through a bulkhead, deck, or console panel without needing to disconnect the cable first. The polished stainless steel dress cap gives it a finished, professional look on any exposed, visible panel or bulkhead location.

Key features

• Fits cable up to 0.56in diameter, with connectors up to 1.40in
• Stainless steel dress cap for a clean, finished appearance
• Mounts with #8 screws, 7/8in on center
• Seals the pass-through against water intrusion once installed

This is a common solution for antenna cables, NMEA 2000 backbone cables, or any other cable that already has a bulky connector molded onto the end — rather than cutting a hole just big enough for the bare cable and struggling to feed the connector through, the CableClam's two-piece clamshell design opens to accept the connector, then closes around the cable to seal the pass-through against water intrusion once fully installed and secured.

Mount it with #8 screws on 7/8in centers, in a location that keeps the seal facing away from direct, sustained water exposure where possible, even though it's designed to be watertight once properly installed. This is a practical upgrade over drilling an oversized, unsealed hole and caulking around it after the fact, and it looks considerably more finished on a helm or console than a bead of sealant around a rough-cut cable pass-through that will eventually crack and let water find its way in.
