Scanstrut

Using marine-rated cable is a must for your boat's stereo system, but you also need watertight installation for your antenna and navigation light cables. This Scanstrut cable seal is easy to install, impact-resistant, and looks great. This cable seal is designed for connectors up to .63" (16mm) and cables from 0.08"-0.35" (2-8mm), and you'll find three different models to choose from. With a tapered bung and a closed-cell base seal, these dome-shaped seals are rugged and water-resistant. Captive nuts make assembly easy and they can be used for repeat installations. The package includes pre-drilled and blank inner seals to make every installation easier. You can choose from rugged gray or white plastic, or opt for the durable, classic look of 316 stainless steel.
