Polished Stainless Steel Cable Gland - Multi Cable (up to 2-17mm each). Watertight installation for your marine electronic cables. The Cable Glands provide waterproof cable routing made of 316 stainless steel. Easy Installation. Each cable gland is supplied with a blank rubber seal that has a molded location to drill and cut. Captive nuts make for easy assembly. Cable connectors do not need to be removed during installation. Watertight Installation. Tapered rubber seal forms watertight installation. Base gasket also provided for clean water tight installation. Improved Shape & Design. Low profile design for a strong, impact-resistant and clean installation (no sharp edges to hit your foot on). Unlike other brands, our inner rubber seal is flush with the top of the cable gland so that water does not have a place to collect.
