6 Best Exterior Cable Clips For Rv Wall Installation

Managing exterior cables on an RV is a constant battle against road vibrations, fluctuating temperatures, and the relentless desire to keep a clean, uncluttered profile. Without proper cable management, loose wires become hazards that can snag on debris or compromise the integrity of exterior seals. Finding the right mounting solution transforms a messy install into a professional, long-term upgrade that stands up to the rigors of mobile living.

Command Outdoor Clips: Damage-Free Installs

Command Outdoor clips excel where owners are hesitant to puncture their RV’s delicate fiberglass or aluminum exterior. These clips utilize weather-resistant adhesive strips designed to withstand UV rays and temperature shifts better than standard indoor alternatives. They are the ideal choice for temporary setups, such as seasonal holiday lighting or short-term satellite dish cabling.

However, recognize the limitations of adhesive technology in high-vibration environments. While excellent for light-duty, temporary runs, they may struggle to maintain a bond under the intense heat of direct sunlight or the constant rattling of a bumpy highway. If a clean removal is the priority over a permanent, structural anchor, these are the gold standard for your kit.

Gardner Bender: Best for Coaxial Cables

Gardner Bender cable clips are a staple for anyone running coaxial lines for internet or television systems. These clips usually feature a reinforced plastic body with a hardened steel nail, specifically designed to secure cables against wooden or composite substrates. They provide a snug, rattle-free fit that prevents the coaxial cable from chafing against the side of the rig during transit.

Be mindful that these require a hammer for installation, which inherently creates a small puncture point. Use these exclusively if the RV exterior has a substantial backing material, such as thick plywood or composite framing, rather than just thin aluminum siding. For those needing a semi-permanent, reliable hold for coax, Gardner Bender offers the mechanical grip that adhesives simply cannot match.

ZesGood Adhesive Clips: Most Versatile Option

ZesGood adhesive clips offer a compact, low-profile footprint that works well in tight spaces like under slide-outs or along wheel wells. Their popularity stems from the ability to bundle multiple smaller wires, such as solar sensor cables or low-voltage LED wiring, into a single anchor point. The adhesive backing is generally more aggressive than standard office-grade solutions, making them better suited for the demands of a nomadic lifestyle.

Think of these as the “utility player” in an RV hardware drawer. They are perfect for interior-to-exterior transitions where space is limited and mechanical fasteners would be overkill. Avoid using these for heavy, rigid cables; they perform best when managing lighter-gauge wiring that doesn’t put constant tension on the adhesive pad.

Eagle Aspen Siding Clips: For Vinyl Siding

Vinyl siding is common on destination-style RVs and park models, presenting a unique challenge for mounting hardware. Eagle Aspen siding clips are specifically engineered to hook into the seams of vinyl siding without requiring any screws, nails, or adhesives. This is a game-changer for maintaining the integrity of the weatherproofing, as you effectively mount your gear without ever breaking the exterior skin.

These clips are purpose-built for the specific profile of residential-style siding, offering a secure, mechanical lock that is surprisingly resilient. Before purchasing, verify the profile of your siding to ensure the clip’s hook matches the gap width. If your rig features this type of siding, these clips are not just recommended—they are the only logical choice.

AMPCOM Screw-In Clips: Heavy-Duty Security

When you have a thick, heavy-gauge shore power cable or a bundle of solar lines that must stay put, AMPCOM screw-in clips provide the ultimate level of security. These are designed to be mechanically fastened directly into the RV wall or frame, ensuring that weight and wind resistance will not pull them loose. They are effectively “set it and forget it” hardware for critical electrical runs.

The trade-off here is clear: you are drilling into the RV. This requires precision and, more importantly, high-quality sealant to prevent moisture intrusion. Only choose these if you are certain about your cable path, as moving them later will leave behind unsightly holes that require patching.

3M VHB Mounts: Pro-Grade Adhesive Solution

3M Very High Bond (VHB) tape is the industry secret for mounting anything on a vehicle without fasteners. By using VHB-backed cable mounts, you create a chemical bond between the clip and the RV skin that is often stronger than the mounting plastic itself. This is the professional choice for solar panel wiring runs where you need a mount to survive wind, rain, and road debris for years on end.

This solution requires meticulous preparation—specifically cleaning the surface with isopropyl alcohol—to achieve the intended bond strength. Once applied, these mounts are incredibly difficult to remove, making them a permanent fixture. For those who want the strength of a screw with the non-invasive nature of an adhesive, VHB mounts are the premier, pro-grade solution.

Choosing the Right Clip for Your RV Wall Type

Not all RV walls are created equal, and the material of your exterior dictates the mounting method. Fiberglass walls are prone to “spider cracking” if drilled incorrectly, making adhesives or VHB a safer bet for beginners. Aluminum siding, conversely, is thin and prone to oil-canning, often requiring mechanical clips that distribute weight across the siding profile.

• Fiberglass/Gelcoat: Use VHB mounts or Command Outdoor clips to avoid cracking the finish.
• Aluminum Siding: Look for clips that attach to seams or use specialized mechanical fasteners that penetrate structural ribs.
• Composite/Laminate: These surfaces hold screws well but require careful sealing; avoid over-tightening to prevent crushing the foam core.

Prepping Your RV Wall for a Secure Bond

No adhesive, regardless of its quality, will function on a dirty surface. Road grime, wax, and oxidation create a barrier that prevents the adhesive from making contact with the actual wall material. Always clean the area with a grease-cutting detergent followed by a wipe-down with 70% or higher isopropyl alcohol.

If the surface is textured, adhesives may struggle to find sufficient contact area. In these cases, consider a small, light sanding with fine-grit paper to flatten the contact patch before cleaning. Following these steps turns a “failed” adhesive clip into a permanent, weather-resistant anchor.

Screw vs. Adhesive: Which Mount Is for You?

Deciding between a screw and an adhesive is a debate of permanence versus structural integrity. Screw-in mounts offer maximum holding power and are immune to the temperature-driven degradation that eventually plagues even the best adhesives. However, every screw hole is a potential failure point for water ingress, which is the primary enemy of any mobile dwelling.

Adhesive mounts are the preferred route for most exterior cable runs because they leave the RV’s factory seal untouched. The compromise is that adhesives have a lifespan; eventually, they will dry out or lose their tackiness under extreme UV exposure. Plan on inspecting and potentially replacing adhesive mounts every two to three years as part of your standard maintenance routine.

How to Seal Screw Holes and Prevent Leaks

If you decide that screws are necessary for a heavy-duty cable run, you must treat the installation like a roofing project. Simply driving a screw into the wall will eventually result in water seeping into the insulation and causing rot. Always pre-drill a pilot hole, then fill the hole with a high-quality, UV-stable lap sealant before inserting the screw.

Once the clip is tightened, apply an additional dab of sealant over the screw head and the base of the clip. This creates a waterproof gasket that prevents moisture from wicking along the threads. A little extra time spent on this step ensures that your cable management project doesn’t turn into a costly water-damage repair down the line.

Effective cable management is the hallmark of a seasoned RV owner, separating long-term, functional rigs from those plagued by constant maintenance headaches. Whether you opt for the non-invasive ease of VHB tape or the rugged permanence of screw-in fasteners, the key is matching the hardware to the specific material and environmental conditions of your build. Take the time to prep your surfaces, seal your penetrations, and secure your lines correctly, and you will enjoy a clean, reliable setup for years to come.
