RX2447V pairs a round acetate front with metal temple arms — a mixed-material build worth noting, since the two parts age differently. This aftermarket pair matches that spec: 145mm metal arms cut for the round acetate front's hinge, the same combination Ray-Ban used on this model. Ordering an all-metal arm meant for a different round Ray-Ban, or an all-acetate one, would miss that mixed build entirely.

Because the front is acetate and the arms are metal, the two rarely wear out on the same schedule — an acetate front can easily outlast two or three sets of arms, since the metal hinge screw and pivot are what take the daily stress of opening and closing. That's the practical reason to replace just the arms here rather than assume the whole frame needs swapping once a temple starts to feel loose.

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 145mm arm to your 2447 frame — the whole swap usually takes under five minutes.

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 2447, mismatches are rare, but you're covered by a 14-day return window if the 145mm 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 145mm arm includes its own hinge barrel, so if the wobble is coming from worn threading on the arm side of the 2447, replacing it usually restores a snug, tight fold.

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 2447 is broken or scratched, or buy the pair if both need replacing — either way they match the 145mm length exactly.
