140mm is the length Ray-Ban settled on for the RX7097, pairing a plastic front with metal temple arms. A compatible replacement needs to match that measurement to keep the fit even on both sides of the square frame, since the plastic front doesn't flex enough to compensate for an arm that runs even slightly short or long.

Metal temples on a plastic-front frame like this one tend to loosen at the hinge screw well before the front shows any wear, since the screw threads take the brunt of repeated folding. Replacing just the arms is a small aftermarket fix next to buying a whole new pair over a part that was still otherwise fine. Checking the hinge for play is usually enough to confirm it's the arm and not the frame.

Frequently asked questions

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 Square style of the 7097 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.

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 7097 is broken or scratched, or buy the pair if both need replacing — either way they match the 140mm length exactly.

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

These arms are made specifically for the 7097, matching its 140mm length and Square 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 7097 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.
