🧰 Tools & Materials You'll Need
- Replacement awning fabric sized for your roller tube (acrylic or vinyl)
- Heavy-duty cotter pin, hardened nail, or thick screwdriver (for pinning manual spring tension)
- High-tensile zip ties (for securing electric awning arms)
- Socket wrench set
- Ladder
- Flathead screwdriver or metal file (for deburring tracks)
- Stiff brush
- Silicone lubricant spray (never WD-40 or grease)
- A second person — a third makes the roller tube much easier to manage
📋 Fabric Replacement, Step by Step
1 Secure the Tension Arms
⚠ Crucial Safety PhaseThe roller tube on manual awnings contains heavy internal torsion springs under immense tension. Skipping this step can cause severe hand or arm injury.
- Partial Deployment: Roll the awning out approximately one to two feet to give you clearance to access the top of the arms and roller end caps.
- Pinning the Spring (Manual Awnings): Locate the small hole in the roller tube end cap and slide a heavy-duty cotter pin, hardened nail, or thick screwdriver all the way through it into the internal spring shaft. This locks the spring so it cannot violently unwind when you unbolt the arms.
- Securing Electric Awnings: Power awnings typically use gas struts or motor gears instead of torsion springs, but the scissor arms are still under pressure. Wrap high-tensile zip ties tightly around the support arm linkages so they can't suddenly buckle or snap open.
- Disconnect Power: On electric awnings, pull the fuse or disconnect the battery so no one can accidentally trigger the switch while you're working.
2 Remove Hardware and Screws
The fabric is held in place by small locking screws at both the RV wall and the roller tube.
- Locate Wall Fasteners: From a ladder, find the sheet metal screws driven through the aluminum awning rail into the fabric's polycord at each outer edge, and back them out completely.
- Locate Roller Tube Fasteners: Check the roller tube grooves for matching locking screws that keep the fabric from sliding during travel, and remove those too.
- Unbolt the Top Brackets: Use a socket wrench to remove the bolts connecting the top of the awning arms to the roller tube end caps. Have your helper support their end of the tube — it will be unsupported once the bolts are out.
3 Slide the Roller Tube Off
This is where a minimum of two people is required — three makes it significantly easier.
- Establish Positions: One person at the front arm, one at the rear. A third person in the middle with a broom or support pole helps prevent the heavy roller tube from sagging and bending.
- The Walking Method: Coordinate your movement and walk slowly in tandem toward the front or rear of the RV, sliding the fabric's polycord completely out of the aluminum roof track.
- Set Up a Workspace: Move the detached roller tube and old fabric onto padded sawhorses, a clean tarp, or soft grass — never bare concrete, which can scratch or dent the tracking grooves.
4 Swap the Fabric
With the assembly on the ground, you can safely remove the old material and prep the tracks.
- Unwind Tension (if removing internal parts): If your fabric instructions require removing the end cap, note the direction and count the exact number of turns to unwind the spring so you can recreate it later. If you pinned the spring successfully in Step 1 and the fabric slides out without cap removal, you can skip this.
- Slide Out the Old Canopy: Pull the old fabric horizontally out of the roller tube channels — it may take some force if it's been baked in place by the sun for years.
- Clean and Deburr: Inspect the aluminum tracking grooves on both the RV wall and roller tube. Use a flathead screwdriver or file to smooth sharp edges or burrs at the track entry points, and brush out dirt, pine needles, and old adhesive.
- Lubricate: Spray silicone lubricant down the entire length of the tracks. Never use WD-40 or grease — they attract dirt and eventually rot the new fabric.
- Feed the New Fabric: Line up the polycords (the plastic beads sewn into the fabric edges) with the roller tube channels and carefully slide the new fabric in straight, making sure it doesn't bunch up or catch.
5 Reinstall and Center
The final phase puts the awning back on the rig and makes sure it rolls up straight.
- Walk It Back On: Align the top fabric polycord with the RV roof rail and slide the fabric back into the wall track while walking the roller tube down the side of the vehicle.
- Reconnect the Arms: Lift the roller tube back up to the vertical support arms and reinstall the mounting bolts to secure the tube end caps.
- Release the Safety Pins: Carefully cut the zip ties (electric) or pull the cotter pins/nails (manual) that locked the springs. Hold the arms firmly to absorb any initial shifting.
- Cycle and Center: Roll the awning fully in and out two or three times, watching the fabric edges — it will naturally shift to find its own center alignment.
- Re-secure Locking Screws: Once the fabric is centered and rolls up without wrinkling, drive the locking screws back into the roof rail track and roller tube to permanently lock it in place.
❓ Frequently Asked Questions
Can I replace RV awning fabric by myself?
It's strongly discouraged. The roller tube is long, heavy, and awkward, and a solo attempt raises the risk of dropping it or letting the spring assembly unwind unexpectedly. Plan for at least one helper, ideally two.
How do I know if I need to replace the fabric or the whole awning?
If the roller tube, arms, and motor or spring assembly are still in good working order and only the canopy is torn, faded, or moldy, a fabric-only replacement is usually all you need.
What size replacement fabric do I need?
Measure the length of your existing roller tube, not the RV's exterior width, and check your awning brand's fitment chart — Carefree, Dometic/A&E, and Zip Dee often use different roller and polycord profiles.
Is it safe to unbolt the arms without pinning the spring first?
No. On manual awnings, an unpinned torsion spring can unwind violently the moment the arms are disconnected, which is the leading cause of injury during this repair. Always pin or otherwise lock the spring first.
