Frequently Asked Questions

How do I know if I need a 115-inch rafter arm versus other lengths?

The rafter arm length should match your awning's projection depth when fully extended. For most standard RV awnings with 8-10 foot projections, the 115-inch arm provides proper support. Measure from your awning roller to the ground at your desired extension angle—the rafter arm should reach comfortably with adjustment room remaining. If your current rafter arm is marked with length specifications, match that measurement.

Can I use this rafter arm on both sides of my awning?

Yes, this rafter arm is designed for universal left or right side installation. Most RV owners use two rafter arms (one on each side) for balanced support, though they are sold individually. Using rafter arms on both sides provides maximum stability and even weight distribution across the awning fabric.

What's the difference between quick deploy and standard rafter arms?

Quick deploy rafter arms feature a spring-loaded mechanism that allows rapid one-handed deployment and retraction, making setup and takedown much faster than traditional twist-lock or pin-style arms. The spring tension holds the arm in position once deployed, while still allowing easy collapse for storage. This design is especially convenient for frequent awning users.

Will this rafter arm work if my awning fabric is aftermarket or non-Dometic?

Yes, the rafter arm attaches to the awning roller tube and ground, not the fabric itself, so it works regardless of fabric brand. As long as your awning hardware is Dometic or A&E brand and the dimensions match, this rafter arm will provide proper support. The arm's function is purely structural support for the awning mechanism.
