RB2448N shares the square metal front and 145mm metal arm length of the broader 2448 family, and this aftermarket pair is built to that same specification so it hinges into the front correctly. Confirming the N suffix and the 145mm size is worth doing before ordering, since the 2448 line covers a few closely related variants that share a similar look but aren't always interchangeable in finish.

On square metal frames like this one, the hinge screw is almost always the point of failure before the arm itself bends or breaks, simply because it's the only moving part. A loose screw shows up as arms that won't hold their angle, and it's a cheaper fix than it looks — though a worn arm calls for a straight swap. Checking both hinges rather than just the one that feels loose is a good habit, since the other side often isn't far behind.

Frequently asked questions

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 2448 frame — the whole swap usually takes under five minutes.

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

Replacing both arms on the 2448 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.

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 2448, mismatches are rare, but you're covered by a 14-day return window if the 145mm arms don't align with your hinge.

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

These arms are made specifically for the 2448, matching its 145mm length and Square hinge design, so they attach to your existing screws and hinge without any filing or adjustment needed.
