The sunglass counterpart to the RX3946V, the RB3946 Clubmaster Oval also takes a 145mm acetate temple matched to its rounded front. A compatible replacement needs to hold that same oval curve, since the Clubmaster Oval sits apart from the squarer Clubmaster styles that share a similar name.

Replacing a cracked or worn acetate arm costs a fraction of a new frame, which matters here since the acetate front on Clubmaster-style models is usually the more involved part to remake. A matched aftermarket arm gets the RB3946 back in service without touching the part that's still fine. It's the more practical route whenever the front and lenses have held up better than the temples. Comparing the arm against the front in natural light is the simplest way to judge whether a shade difference is really a mismatch.

Frequently asked questions

Are these official Ray-Ban replacement parts?

These are compatible aftermarket arms, independently produced to match the 3946'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 3946, matching its 145mm length and Oval hinge design, so they attach to your existing screws and hinge without any filing or adjustment needed.

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 3946, mismatches are rare, but you're covered by a 14-day return window if the 145mm arms don't align with your hinge.

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

Replacing both arms on the 3946 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.
