Round-bodied despite its browline design, the RB4246 Clubround uses a 145mm acetate temple built to match the front's curve. A compatible replacement needs to follow that same curve as well as the length, since a straighter aftermarket arm can still close at the hinge while sitting oddly against the rounded front.

The temple tip, the small piece behind the ear, is thinner than the rest of the arm and is usually the first part to chip or wear through on an acetate frame like this one. Once that tip goes, the whole arm typically needs replacing rather than just the end piece. It's worth checking there before assuming the whole RB4246 needs more extensive work. A quick comparison against a clear photo of the frame's finish is worth doing before ordering, since acetate tones can vary subtly between batches.

Frequently asked questions

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 Round style of the 4246 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.

What if the arms arrive and the hinge doesn't line up with my frame?

Because each pair is listed against a specific model, in this case the 4246, mismatches are rare, but you're covered by a 14-day return window if the 145mm arms don't align with your hinge.

Are these official Ray-Ban replacement parts?

These are compatible aftermarket arms, independently produced to match the 4246's hinge and 145mm length. They aren't manufactured or supplied by Ray-Ban, just built to the same measurements so they attach correctly.

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

These arms are made specifically for the 4246, matching its 145mm length and Round hinge design, so they attach to your existing screws and hinge without any filing or adjustment needed.
