Genuine Ray-Ban part — guaranteed
A genuine Ray-Ban RB4105 folding bridge bar, sourced directly from Ray-Ban — never an aftermarket copy. Made to the original specification so it folds and fits exactly as it should.
Which size do you need?
Match the bridge to your frame's eye size
The RB4105 comes in two eye sizes, each taking a different bridge bar. Pick the one that matches yours:
Not sure of your size? Look inside the temple arm (the part that rests on your ear). After RB4105 you'll see two numbers like 54☐15 — the second number is your bridge size. So 54☐15 → choose the 15mm bar. Still unsure? Send us a photo and we'll check.
About the RB4105 folding bridge bar
The RB4105 is Ray-Ban's iconic folding Wayfarer — the version that folds down to pocket size. The bridge bar is the sprung metal piece across the top of the lenses that lets the frame fold and holds its shape. If yours is bent, loose or has snapped, a genuine replacement restores both the fold and the original fit. A common, straightforward fix that brings a much-loved frame back to life.
Fitting your bridge bar
The bridge bar fixes in place with two small screws. Screws aren't included — most replacements reuse the originals, but if yours are lost or worn you can add a pair of genuine Ray-Ban screws.
