RB3605N keeps to Ray-Ban's common 140mm temple length, using metal arms with an aviator curve set into a plastic front. This aftermarket pair follows that same curve, so it hinges into the front correctly instead of the straighter arm profile built for Ray-Ban's square sunglasses. Because several plastic-front Ray-Ban models share a broadly similar aviator taper, ordering against the 3605N code specifically is what keeps the hinge fit accurate.

When only one arm is bent or missing, there's no need to replace the pair as a set — a matched single arm restores symmetry, since Ray-Ban's aviator-style plastic-front frames use the same arm on both sides at this size. Confirm the model code rather than ordering by shape alone, since several similarly-curved Ray-Ban lines share this general look. Testing that both temples fold to the same angle once fitted is a quick final check before considering the swap done.

Frequently asked questions

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

Replacing both arms on the 3605 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.

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

These arms are made specifically for the 3605, matching its 140mm length and Aviator hinge design, so they attach to your existing screws and hinge without any filing or adjustment needed.

My hinge feels loose — will new arms fix that, or is it the frame that's worn?

A new 140mm arm includes its own hinge barrel, so if the wobble is coming from worn threading on the arm side of the 3605, replacing it usually restores a snug, tight fold.

Do I need a specific screwdriver to attach these myself?

You'll need a small eyeglass screwdriver, typically included in basic repair kits, to remove the old hinge screw and attach the new 140mm arm to your 3605 frame — the whole swap usually takes under five minutes.
