DS21B Vertical Cable Seal

The Scanstrut DS21B Vertical Cable Seal is designed for cables from 9-14mm (0.16″-0.35″) and connectors up to Ø21mm (0.82″). Featuring a dome-shaped profile, it offers superior impact resistance with an aesthetic, low-profile finish ideal for any marine installation.

Available in Grey, Black, or 316 Stainless Steel

Choose from grey or black high-impact plastic, or upgrade to premium marine-grade 316 stainless steel for maximum corrosion resistance and durability in harsh marine environments.

Multi-Functional Dome Shape

The strong dome-shaped design provides both an additional water shield and a robust, impact-resistant structure for your cable installation.

Watertight IP68 Installation

Supplied with a tapered bung and closed base seal, the DS21B ensures a fully watertight installation (IP68-rated) to protect electrical connections even in the harshest conditions.

Easy and Reliable Assembly

Captive nuts make assembly fast and simple while allowing repeat installations without hassle. Each seal includes both pre-drilled and blank inner seals for a tailored fit.

Split Bungs for Connector Ease

The split-seal option allows installation without removing existing connectors up to Ø21mm (0.82″), making your project more efficient.
