Measure your existing rafter arm from end to end when fully collapsed. If your current rafter measures approximately 74 inches and is polar white, this is likely the correct replacement. Check your awning's model documentation or contact our parts specialists with your awning model number for confirmation.\u003c\/p\u003e\n\n\u003ch3\u003eWhat's the difference between a rafter arm and the main awning arms?\u003c\/h3\u003e\n\u003cp\u003eRafter arms (also called support arms) are the additional stabilizing poles that run from the awning roller tube down to the ground at an angle. They're separate from the main extending arms that attach to your RV. Rafters provide extra support to prevent fabric sag and reduce stress on the primary awning mechanism, especially important in windy conditions.\u003c\/p\u003e\n\n\u003ch3\u003eCan I use just one rafter, or do I need to replace both?\u003c\/h3\u003e\n\u003cp\u003eWhile you can replace a single damaged rafter, most RV awnings use two rafter assemblies (one on each side) for balanced support. If one rafter is worn or damaged, the other is likely experiencing similar wear. For optimal awning stability and appearance, consider replacing both rafters at the same time.\u003c\/p\u003e\n\n\u003ch3\u003eIs this rafter assembly difficult to install?\u003c\/h3\u003e\n\u003cp\u003eInstallation is straightforward for most RV owners with basic tools. The rafter typically attaches to the awning roller tube with a bracket and extends down to rest on the ground or attach to a mounting point. Always refer to your awning's installation manual and ensure the awning is properly secured before making any adjustments. If you're uncomfortable working with your awning hardware, consult a qualified RV technician.\u003c\/p\u003e\n\n\u003ch2\u003eWhy Choose Elkhart RV Parts?\u003c\/h2\u003e\n\u003cp\u003eAt ElkhartRVParts.com, we specialize in hard-to-find Dometic replacement parts that keep your RV systems running smoothly.
