Ray-Ban's 3597 Wings model uses a square metal front with 140mm arms, and this aftermarket pair reproduces that length and all-metal build so it hinges into the front the same way the factory temple did. The Wings line has a distinctive brow bar, but the arm attachment itself follows the same square-front hinge geometry as other metal Ray-Ban styles at this size, so the swap doesn't involve any unusual hardware.

Metal-on-metal hinges like this one are simple mechanically, but they rely entirely on the screw staying tight, since there's no plastic bushing to take up slack. If the arms start to droop or won't hold an angle, a small flathead screwdriver and a quarter-turn is usually the whole fix — no need to replace the arm itself unless it's actually bent or broken. Keeping a spare screw of the same small gauge on hand is a good habit, since these are easy to lose during a quick fix.

Frequently asked questions

Are these official Ray-Ban replacement parts?

These are compatible aftermarket arms, independently produced to match the 3597's hinge and 140mm 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 Square style of the 3597 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.

Is it worth buying new arms instead of a whole new frame?

Replacing both arms on the 3597 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.

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 3597 is broken or scratched, or buy the pair if both need replacing — either way they match the 140mm length exactly.
