Blue Sea Side CableClam Review Pros & Cons

Blue Sea Side Entry CableClam Max Cable Dia 0.28in for Boats & Marine Engines
Introduction
The Blue Sea Side CableClam Max Cable Dia 0.28in for Boats & Marine Engines is a reliable, waterproof cable management solution designed for side entry applications where deck penetration isn’t possible or preferred. Engineered for high-performance marine environments, this product provides superior sealing for electrical cables on any vessel. It’s a favorite among boat builders and DIY installers alike for its ease of installation, compact design, and robust performance under extreme marine conditions.
As marine technology continues to evolve, so does the need for reliable cable sealing products that can handle the harsh elements of saltwater exposure, high humidity, and continuous motion. The Blue Sea Side CableClam fits the bill perfectly — offering a corrosion-resistant, secure, and flexible cable routing solution that integrates seamlessly into a boat’s electrical system.
Overview / What Is Blue Sea Side CableClam Max Cable Dia 0.28in
The Blue Sea Side CableClam Max Cable Dia 0.28in for Boats & Marine Engines is a side-entry cable gland specifically crafted to seal cables passing through bulkheads or flat vertical surfaces. Unlike traditional top-mount CableClams, this version allows lateral cable entry, making it ideal for tight installations or retrofit scenarios where vertical space is restricted.
Built with UV-stabilized plastic and marine-grade rubber, it forms a watertight seal around a single cable up to 0.28 inches in diameter. The cover is removable, enabling users to install or replace pre-terminated cables without cutting connectors — a huge plus for sensitive marine electronics installations.
Benefits of Using Blue Sea Side CableClam on Boats
Every boat requires reliable sealing solutions to protect its electrical components. The Blue Sea Side CableClam offers a host of benefits for marine applications:
- Side Entry Configuration: Enables installation in tight spaces and vertical surfaces.
- Seals Out Moisture: Protects sensitive electronic equipment from water damage.
- Quick Installation: No need to cut factory connectors — ideal for plug-and-play systems.
- UV & Weather Resistant: Built for durability in all weather conditions.
- Flexible Use Cases: Suitable for GPS wires, VHF cables, fishfinder leads, and more.
Whether used in new installations or refits, this side CableClam delivers a clean, professional finish that enhances both function and appearance on any boat.
How to Install Blue Sea Side CableClam Max Cable Dia 0.28in
Proper installation is key to ensuring waterproof integrity. Here’s a step-by-step guide:
- Choose a flat, vertical surface for mounting that avoids interference with moving parts.
- Drill a pilot hole that matches the diameter of your cable.
- Remove the cover, and make a small slit in the rubber insert if your cable is pre-terminated.
- Route the cable through the gasket and base, then secure the cover back in place.
- Use a marine-grade sealant around the base for additional protection.
Installation takes under 10 minutes and provides lasting protection for your marine electronics. It’s an especially useful product for retrofitting cables into cabins or console panels without dismantling the system.
Comparing Side Entry vs Top Entry CableClams
Many boaters are unsure whether they need a top-entry or side-entry CableClam. Here’s a breakdown of their key differences:
- Side Entry: Best for tight vertical spaces, like console side panels or bulkheads.
- Top Entry: Designed for deck-level routing like antennas or mast wiring.
For most boats, both types serve unique purposes. The Blue Sea Side CableClam is often used in conjunction with top-entry units to build a complete, sealed cable infrastructure throughout the vessel.
Maintenance Tips
Though rugged by design, the Blue Sea Side CableClam Max Cable Dia 0.28in for Boats & Marine Engines still benefits from routine maintenance. Keeping it clean and intact ensures long-term watertight performance.
- Rinse After Saltwater Exposure: Use fresh water to clean off salt residue.
- Inspect Rubber Gasket: Look for signs of cracking or wear and replace if needed.
- Reapply Sealant Annually: Especially in high-traffic or vibration-heavy areas.
- Check Screw Tightness: Vibration can slowly loosen hardware over time.
Preventive maintenance ensures the CableClam retains its protective seal and aesthetic appeal for years to come.
Expert Advice and Pro Recommendations
Marine electricians and boat manufacturers alike recommend using the Blue Sea Side CableClam Max Cable Dia 0.28in for Boats & Marine Engines for small to mid-sized cables where side entry is required. Its unique orientation makes it a must-have for tight cabins, helm stations, or any retrofit where drilling vertically is impractical.
Pair it with marine-grade silicone, tinned copper wire, and waterproof heat shrink connectors for a truly professional installation. Always ensure that the cable jacket isn’t damaged during insertion and that all fittings are watertight before finalizing.

Detailed FAQ Section
Can the Blue Sea Side CableClam be used for pre-terminated cables?
Yes, the Blue Sea Side CableClam is specifically designed to work with pre-terminated cables. The rubber insert can be slit carefully to allow connector heads to pass through without cutting or splicing the cable. This is especially helpful when dealing with expensive or sensitive electronics like GPS, sonar, or VHF systems. Just ensure the cut remains tight around the cable to preserve waterproof integrity.
What types of cables work best with the 0.28in size limit?
Cables up to 0.28 inches (approximately 7mm) in outer diameter are supported. This includes VHF coaxial, GPS antenna leads, power and data cables for fishfinders, and other low-voltage electronics wiring. It’s important to measure the widest portion of the cable (including insulation) to ensure compatibility. If your cable is close to the max size, test-fit it before finalizing installation to ensure a tight seal.
Is it suitable for use on aluminum boats?
Absolutely. The CableClam base and cover are made of non-corrosive materials that are compatible with aluminum surfaces. To maximize lifespan and adhesion, apply a corrosion-resistant marine sealant between the CableClam and the boat hull. Use stainless steel screws or rivets that won’t react with aluminum. With proper installation, it works flawlessly on jon boats, pontoons, and aluminum center consoles.
How long does the gasket last under heavy sun exposure?
The gasket is constructed with UV-stabilized rubber specifically intended for prolonged sun exposure. In normal boating conditions, it can last 5–8 years before showing signs of aging like hardening or cracking. Rinsing with freshwater and storing your boat under cover when not in use can extend this lifespan significantly. Replacement gaskets are available from Blue Sea Systems if needed.
Does it require drilling for installation?
Yes, you’ll need to drill a hole slightly larger than the cable’s outer diameter and mount the CableClam using the provided screws. A standard drill and marine sealant are all that’s required. Be sure to double-check the mounting area for clearance behind the panel, and avoid hitting wires or hidden components. The process is simple, takes under 10 minutes, and provides professional-grade results.
Conclusion
The Blue Sea Side CableClam Max Cable Dia 0.28in for Boats & Marine Engines is an essential component for clean, waterproof cable routing in tight or vertical installations. Its side-entry design, ease of use, and long-term reliability make it a standout solution for professional boaters and DIYers alike. Whether you’re upgrading existing systems or building from scratch, this product delivers trusted performance in harsh marine environments.
Don’t overlook the importance of quality cable management — it’s not just about aesthetics but also about safety and durability. Choose a CableClam built to endure the elements and protect your investment.
