Understanding the Basics: What is an RV Awning Traplestrip?
Before we jump into the manual labor, we need to define exactly what we are working with. The “traplestrip,” often referred to in the industry as a vinyl insert trim or track seal, is the flexible plastic or rubber strip that slides into the center channel of your RV awning rail. Its primary job is to hide and protect the mounting screws that hold the rail to the side of your vehicle.
Without this strip, water can pool inside the C-channel, leading to oxidation of the aluminum and eventual rust on the screw heads. Over time, that moisture can even seep into the screw holes, causing delamination of your fiberglass or rotting the wood framing inside your walls. Learning how to rv awn traplestrip properly is essentially an insurance policy for your RV’s structural integrity.
These strips come in various widths, though 1-inch and 3/4-inch are the most common sizes. They are usually made from UV-resistant vinyl, but even the best materials eventually succumb to the sun’s rays. If your current strip is cracked, shrinking, or falling out, it is time to get to work.
Signs You Need to Replace Your Awning Track Insert
How do you know when it is time to stop procrastinating? Usually, the visual cues are quite obvious if you know where to look. Inspect the length of your awning rail during your pre-trip walkaround. If you see the vinyl pulling away from the ends, that is a classic sign of thermal shrinkage.
Look for discoloration or a chalky residue on the surface of the strip. This indicates that the UV inhibitors in the plastic have broken down. If the material feels brittle or snaps when you poke it with a finger, it can no longer provide a tight seal. At this point, moisture is definitely getting behind the rail.
Another red flag is mold or mildew growing inside the track. This means water is trapped behind the strip and cannot evaporate. If you notice any of these issues, you need to know how to rv awn traplestrip to prevent a small maintenance task from turning into a multi-thousand-dollar water damage repair.
Essential Tools and Materials for the Job
One of the best things about this project is that it requires very few specialized tools. However, having the right supplies on hand will make the process much smoother. You don’t want to be stuck halfway up a ladder realizing you forgot a basic item.
- Replacement Vinyl Insert: Ensure you measure the width of your track (usually 1″ or 3/4″) and buy a roll long enough for the entire rail.
- Non-marring Pick or Flathead Screwdriver: Useful for prying out the old, brittle pieces of the previous strip.
- Bucket of Soapy Water: A mixture of Dawn dish soap and water acts as an excellent lubricant for the new strip.
- Spray Silicone Lubricant: For particularly tight tracks, a dry silicone spray can work wonders without attracting dirt later.
- Utility Knife or Sharp Scissors: To trim the excess material at the ends.
- Steady Ladder: Use an A-frame ladder that allows you to reach the rail comfortably without overextending.
I always recommend buying a few extra feet of the vinyl trim. It is inexpensive, and having a bit of slack allows you to account for future shrinkage. Some pros even suggest letting the new strip sit in the sun for 20 minutes before installation to make it more malleable and easier to work with.
Step-by-Step: How to rv awn traplestrip Replacement
Now that you have your supplies, it is time to get to work. Follow these steps carefully to ensure a professional finish that will last for years. Safety is your first priority, so ensure your ladder is on level ground and you have a spotter if possible.
Step 1: Removing the Old Strip
Start at one end of the awning rail. Use your pick or screwdriver to gently pry up the edge of the old vinyl. If the strip is old and brittle, it might break into small chunks. This is normal, though it does make the job a bit more tedious.
Pull the strip out of the channel along the entire length of the rail. If you encounter a screw that is backing out, take a moment to tighten it back down. This is the perfect time to inspect the butyl tape or sealant behind the rail to ensure it hasn’t failed.
Step 2: Cleaning the Track
You cannot skip this step. Use your soapy water and a stiff brush to scrub out the inside of the C-channel. Years of road grime, bug guts, and old wax build up in there. If the track is dirty, the new strip will be nearly impossible to slide in.
Once cleaned, rinse the track and let it dry, or wipe it down with a clean rag. For a truly professional job, run a microfiber cloth dampened with a bit of rubbing alcohol through the track to remove any remaining oily residue. A clean track is the secret to a smooth installation.
Step 3: Lubrication and Starting the Insert
Apply a small amount of silicone spray or soapy water to the first few inches of the track. Take your new vinyl strip and fold it slightly to fit the edges into the top and bottom grooves of the channel. Most people find it easiest to “pinch” the strip as they feed it in.
If the track is very tight, you can try sliding the strip in from the very end of the rail. However, if the awning end caps are in the way, you will need to “snap” it in by pressing one edge into the groove and using a dull putty knife to pop the other edge into place. This is where knowing how to rv awn traplestrip correctly saves your fingertips from getting sore.
Step 4: Feeding the Strip
Work your way down the rail, pressing the strip into the channel every few inches. Avoid pulling or stretching the vinyl as you go. If you stretch it, the material will eventually “snap back” as it cools, leaving gaps at the ends of your rail. Use a relaxed hand and let the material sit naturally in the track.
If you encounter a stubborn section, apply more lubricant. If the strip refuses to pop in, check for a burr in the aluminum rail or a screw head that isn’t sitting flush. A small file can quickly smooth out any rough spots in the metal that might be snagging the vinyl.
Step 5: Trimming and Finishing
Once you reach the end of the rail, leave about an extra half-inch of material on both sides. Use your utility knife to make a clean, square cut. Tuck the excess into the end caps if your rail has them, or simply let it sit flush with the end of the metal.
Some mechanics like to use a tiny dab of clear sealant at the very ends of the strip to prevent it from sliding out during travel. This isn’t always necessary, but it provides extra peace of mind if you frequently drive in high-wind conditions or off-road environments.
Advanced Tips for a Long-Lasting Seal
If you want to go beyond the basics, there are a few expert tricks you can use. First, consider the color of your strip. While black is common, it absorbs the most heat and tends to shrink faster than white or silver inserts. If your RV is parked in the desert sun, a lighter color might actually extend the life of the seal.
Another pro tip is to use a heat gun on a very low setting (or a hair dryer) if you are doing this job on a cold morning. Cold vinyl is stiff and unforgiving. A little bit of warmth makes it much more flexible, allowing it to conform to the curves of the awning rail without fighting you every step of the way.
Lastly, always check the integrity of the rail itself. If the aluminum is bent or crimped, the strip will never sit correctly. You can use a pair of duckbill pliers to gently straighten any sections of the track that were damaged by low-hanging branches or previous repair attempts. This ensures the how to rv awn traplestrip process results in a watertight finish.
Safety Considerations for DIY RV Repairs
Working on the roofline of an RV presents unique risks. Always ensure your ladder is rated for your weight and is placed on a firm, non-slip surface. Never lean the ladder directly against the awning fabric, as this can tear the material or cause the ladder to shift unexpectedly.
If you are working on a large Class A motorhome or a tall fifth wheel, the height can be intimidating. Don’t be afraid to ask a friend to hold the ladder. If you feel dizzy or uncomfortable with heights, this is a task that any mobile RV mechanic can handle quickly. Safety is always more important than saving a few dollars on labor.
Wear eye protection when removing old, brittle strips. As they snap, small shards of plastic can fly toward your face. Additionally, be mindful of the sharp edges of the aluminum rail. It is easy to slice a finger while cleaning the track if you aren’t careful.
Maintaining Your New Awning Track Strip
Now that you’ve successfully completed the installation, you want it to last. The best way to maintain your work is through regular cleaning. When you wash your RV, use a soft brush to remove dirt from the edges of the vinyl strip. This prevents grit from working its way behind the seal.
Twice a year, apply a UV protectant spray (like 303 Aerospace Protectant) to the strip. This creates a barrier against the sun and keeps the vinyl from becoming brittle. It only takes two minutes but can double the lifespan of your insert. Keeping the material supple is the key to maintaining a watertight barrier.
Keep an eye on the ends of the strip after long trips. The vibrations of the road can sometimes cause the strip to “creep” or shift in the track. If it moves, simply slide it back into place and consider adding that small dab of sealant we mentioned earlier to lock it down permanently.
Frequently Asked Questions About how to rv awn traplestrip
What is the most common size for an RV awning track strip?
Most modern RVs use a 1-inch wide vinyl insert. However, older campers or specific brands might use a 3/4-inch or even a 5/8-inch version. It is always best to measure your old strip or the width of the channel before ordering your replacement material.
Can I use silicone caulk instead of a vinyl strip?
While you could technically fill the channel with caulk, it is not recommended. Caulk is messy, difficult to remove later, and doesn’t provide the same clean aesthetic as a proper insert. Furthermore, the vinyl strip allows for the natural expansion and contraction of the aluminum rail without cracking.
How often should I replace the awning traplestrip?
On average, these strips last between 3 to 5 years depending on your climate. If you live in a high-UV area like Arizona or Florida, you might need to replace them more frequently. If the strip looks cracked or is shrinking away from the ends, it’s time for a change.
Does the strip come in different colors?
Yes, you can find replacement strips in white, black, silver, and even beige. Choosing a color that matches your RV’s trim or awning hardware provides a much more integrated look. Most enthusiasts prefer black or white as they are the easiest to find at any camping supply store.
What if my awning rail is curved?
The vinyl material is designed to be flexible. For curved rails, using a bit of heat (like a hair dryer) is essential. Warm the strip up until it is very soft, and it will easily follow the contours of the rail. Once it cools, it will retain that shape and stay securely in place.
Conclusion: Stay Dry and Hit the Road
Taking the time to learn how to rv awn traplestrip is a hallmark of a responsible owner. It is a simple, low-cost project that provides massive benefits in terms of leak prevention and aesthetic appeal. By following the steps outlined above—cleaning the track, using proper lubrication, and avoiding over-stretching the material—you ensure your RV stays protected from the elements.
Don’t let a brittle, failing seal lead to expensive sidewall repairs. Grab a roll of high-quality vinyl trim, a sturdy ladder, and spend an hour refreshing your rig. It’s these small DIY victories that keep our vehicles on the road and our campsites comfortable. Now that your awning rail is sealed tight, you can focus on what really matters: the next adventure on the horizon.
Stay safe, keep the water out, and enjoy the great outdoors!
