Rectangular and metal, the RX3610V's temple arm runs 140mm, built for this model's optical (Rx) front rather than a generic rectangular size. A compatible replacement needs to hold both that length and the flat rectangular profile to sit correctly at the hinge.

Rectangular metal temples run as a straight, flat bar rather than a curved wire, so when one does bend it's usually a sharp kink rather than a gentle curve. That kind of bend rarely straightens back true, which is why replacing the arm is more reliable than trying to fix it by hand. A compatible 140mm aftermarket arm restores a flush fold against the front without any further tinkering. Confirming the RX designation on the frame before ordering avoids ending up with an arm cut for the sunglass version instead.

Frequently asked questions

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 3610 frame — the whole swap usually takes under five minutes.

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

These arms are made specifically for the 3610, matching its 140mm length and Rectangle 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 3610 costs from €25.95 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.

Can I replace just one arm, or do I have to buy both?

You can order a single side if only one arm on your 3610 is broken or scratched, or buy the pair if both need replacing — either way they match the 140mm length exactly.
