FAQ

Is the price for one arm or for the pair?

The price is for a complete pair: original Ray-Ban right and left arms.

How do I know if I need 140 mm?

The length usually appears at the end of the inscription on the inside of the arm. Select the same measurement shown on your current frame.

Are hinge screws included?

No. Screws are offered as an optional add-on because many frames allow you to reuse the existing ones.

Why might the inside reference be different?

Original replacement arms may use a different manufacturing number, even though their shape, size, color and compatibility match the RB4321CH.

Can I choose a different color from my frame front?

You can, but we recommend selecting the frame's color code to keep a uniform finish.
