Frequently Asked Questions
Can I cut this rail to fit a shorter awning?
Yes, aluminum awning rails can be cut to length using a hacksaw or metal cutting blade. Measure carefully and deburr the cut edge before installation. Always cut from the end without pre-drilled holes if possible.
What hardware do I need to install this awning rail?
Installation typically requires stainless steel screws with sealant, appropriate for your RV's sidewall construction (wood, aluminum, or fiberglass). Spacing should be 12-16 inches on center. Always use a quality RV sealant like Dicor or Sikaflex to prevent water intrusion.
Will this rail work with my existing Dometic awning fabric?
Yes, this rail features the standard Dometic profile that accepts the rope bead sewn into Dometic awning fabrics. It's compatible with most Dometic manual and power awning systems that use rail-mounted fabric.
How do I remove the old awning rail without damaging my RV?
Carefully remove screws and use a plastic putty knife to separate the rail from the sidewall. Remove old sealant with a plastic scraper and mineral spirits. Clean the surface thoroughly before installing the new rail with fresh sealant.
