The RB1969 Rectangle is the sunglasses version of Ray-Ban's 1969 frame, built with a rectangular metal front and 140mm metal arms. This aftermarket set matches that straight-edged profile, so the arm sits flush against the front the same way it does on the factory pair, rather than curving in like an oval or round style would. The RX1969V prescription version shares the same rectangular shape, so the RB prefix is what marks this as the sunglasses variant specifically.

Rectangular metal sunglasses like this one are usually stored folded in a case more than worn on a cord, which puts repeated stress on the hinge fold rather than on the lenses or front. If the arms have gotten loose or won't stay folded flat, that's ordinary hinge wear, not a sign the frame is failing. A stiff new hinge that loosens slightly over the first few weeks of wear is normal and not a sign the arm was cut wrong.

Frequently asked questions

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 1969 is broken or scratched, or buy the pair if both need replacing — either way they match the 140mm length exactly.

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 140mm arm to your 1969 frame — the whole swap usually takes under five minutes.

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 1969 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 140mm arm includes its own hinge barrel, so if the wobble is coming from worn threading on the arm side of the 1969, replacing it usually restores a snug, tight fold.
