Ray-Ban's RX5154 Clubmaster eyeglasses use a 145mm acetate arm on a rectangular front, and that's the spec this aftermarket pair follows. Being a prescription frame rather than the sunglass version doesn't change the arm dimensions — the RX and RB Clubmaster lines share the same temple length and hinge position, only the lens type differs.

On Clubmaster-style frames, the brow bar rivets are usually the first thing to loosen, but that's a front-frame issue and won't be solved by a new arm. What a replacement temple does fix is the more common arm-side problem: a worn hinge screw thread or a hairline crack at the tip from months of daily folding. If the rivets up front are still tight and it's just the temple that's failed, the arm alone is the part to swap.

Frequently asked questions

Are these official Ray-Ban replacement parts?

These are compatible aftermarket arms, independently produced to match the 5154's hinge and 145mm length. They aren't manufactured or supplied by Ray-Ban, just built to the same measurements so they attach correctly.

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 Rectangle style of the 5154 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.

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 5154, 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 5154 is broken or scratched, or buy the pair if both need replacing — either way they match the 145mm length exactly.
