Metal temples at 140mm are what the RX6466's square frame calls for, and a compatible arm needs to hold that length precisely to sit right against the front. A shorter or longer aftermarket arm will still technically fit the hinge, but it changes how the glasses balance on the face.

A bent temple is the most common reason to replace arms on a squared metal frame like this one; the front usually stays straight and undamaged, so there's no need to replace more than the part that actually failed. Confirming the bend is in the arm and not the front hinge itself is worth doing before ordering a replacement, since the two problems look similar at a glance. Confirming the model number stamped on the inside of the temple is the simplest way to make sure a replacement will actually match.

Frequently asked questions

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 6466, mismatches are rare, but you're covered by a 14-day return window if the 140mm arms don't align with your hinge.

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 6466, replacing it usually restores a snug, tight fold.

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

These arms are made specifically for the 6466, 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 6466 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.
