Clubround, as the name suggests, takes the Clubmaster's browline styling and rounds off the front — RX4246V's version pairs that round front with a 145mm acetate arm, which this aftermarket pair matches. The round front changes the hinge angle compared with the squarer Clubmaster models, so arms cut for those won't sit quite right here.

Round-front acetate arms like this one flex slightly more at the hinge with every use than a straighter, squarer arm would, which is normal and part of why the hinge barrel — not the acetate itself — is usually the first thing to loosen. If the arm is discolouring evenly or has a small hairline mark near the tip, that's cosmetic acetate ageing rather than a structural problem; an actually loose or cracked hinge is the real sign it's time to swap the arm.

Frequently asked questions

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

Replacing both arms on the 4246 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 145mm hardware itself.

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 145mm arm to your 4246 frame — the whole swap usually takes under five minutes.

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.
