The 4292N Blaze Doublebridge pairs a plastic front with 140mm metal arms curved for its rounded profile, and this aftermarket set matches that curve and length so the temple meets the plastic hinge the way the factory arm did. The doublebridge detail sits on the front, not the arm, so the temple itself follows the same rounded geometry as other Blaze-series Ray-Ban frames, and the swap doesn't touch that bridge detail at all.

Plastic-front, metal-arm frames like this one usually show wear at the hinge bushing before the plastic itself fades or cracks, since the metal arm is the harder of the two materials at that pivot point. A slightly loose or gritty-feeling hinge is normal wear there, and a fresh arm resolves it without touching the front. Folding the arms flat after fitting is a quick way to confirm the hinge has seated correctly rather than just checking that the screw feels tight.

Frequently asked questions

Are these official Ray-Ban replacement parts?

These are compatible aftermarket arms, independently produced to match the 4292'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 Redondo style of the 4292 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.

How do I know these arms will fit my Ray-Ban frame?

These arms are made specifically for the 4292, matching its 140mm length and Redondo hinge design, so they attach to your existing screws and hinge without any filing or adjustment needed.

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 4292 frame — the whole swap usually takes under five minutes.
