Designed for a range of Starlink®, NMEA and RJ45 cable and connector diameters, the DS-HSL-01 Horizontal Cable Seal provides a clean, reliable cable routing solution for rooftop installations. 

The supplied split pre-drilled bungs allow cables with connectors already attached to pass through the seal, removing the need to cut and re-terminate connectors during installation. Multiple bung sizes and a self-drill option allow installers to easily customise the fit while maintaining a watertight seal.

Based on our most popular horizontal cable seal design, the low-profile construction is impact-resistant and offers additional protection against water ingress. The horizontal cable entry keeps the cable exit as close as possible to the mounting surface, creating a neat, professional installation.

Suitable for cables ranging from 2–8 mm (0.07”–0.31”), the DS-HSL-01 is ideal not only for Starlink installations but also for solar panels, light bars, lighting and other rooftop electronics.

Marine Grade Materials

Manufactured from premium UV-stable, hard-wearing materials, the DS-HSL-01 is built for long-term outdoor performance. Rated IP68, it delivers a guaranteed 100% watertight seal in demanding marine and outdoor environments.

Easy Installation

Captive nuts ensure a fast and reliable installation while allowing repeat fitting if required. The easy-fit cable routing system helps reduce installation time and delivers a clean, professional finish.
