Outdoorsman II styling on the RB3407 pairs a 140mm metal temple with its aviator front, and a compatible arm needs to match both to sit correctly. Outdoorsman-style aviators tend to see heavier daily use than dressier styles, which makes matching the arm properly even more worthwhile, especially for anyone wearing them outdoors on a regular basis.

Thin metal aviator temples like this one don't straighten back cleanly once bent: the wire core tends to weaken at the bend point, which usually shows up as a persistent kink even after trying to fix it by hand. Replacing the arm outright is the more reliable route. A compatible 140mm aftermarket arm restores the fit without the guesswork of judging how much life is left in a bent, previously repaired temple. Checking both arms at once is worth doing on a frame that sees this much regular wear, so the fit stays even on both sides rather than fixing one side today and the other in a few months.

Frequently asked questions

How do I know these arms will fit my Ray-Ban frame?

These arms are made specifically for the 3407, matching its 140mm length and Aviator hinge design, so they attach to your existing screws and hinge without any filing or adjustment needed.

Is it worth buying new arms instead of a whole new frame?

Replacing both arms on the 3407 costs from €26.95 with free worldwide shipping, far less than a new frame, and it's backed by a 3-year warranty against manufacturing defects on the 140mm hardware itself.

What material are the arms made from, and will the color match my frame?

The arms are molded in an acetate or metal finish that matches the Aviator style of the 3407 closely, though very slight shade variation is possible since they're independently produced as separate aftermarket parts rather than cut from the same batch as the frame.

What if the arms arrive and the hinge doesn't line up with my frame?

Because each pair is listed against a specific model, in this case the 3407, mismatches are rare, but you're covered by a 14-day return window if the 140mm arms don't align with your hinge.
