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.

Good to know
Check your bridge size before ordering — the two bars aren't interchangeable. If you order the wrong one, it's stocked rather than custom-made, so we can swap it: email us and we'll sort it out.
All fittings and repairs are carried out at the customer's own risk.
Common questions
Which bridge size do I need?
It depends on your frame's eye size: choose the 15mm bar for a 54mm eye size, or the 20mm bar for a 50mm eye size. To check, look inside the temple arm — after “RB4105” you'll see two numbers like 54▢15, and the second number is your bridge size.
Is this a genuine Ray-Ban part?
Yes. It's an authentic Ray-Ban RB4105 bridge bar sourced directly from Ray-Ban, made to the original specification — never an aftermarket copy.
Will it fit my Ray-Ban folding Wayfarer?
This bridge bar is made for the Ray-Ban RB4105 folding Wayfarer, in the two sizes above. If your frame is a different model, get in touch and we'll point you to the right part.
Does it come with screws?
No — the bridge bar is supplied on its own. Most replacements reuse the original screws, but if yours are missing or worn you can add a pair of genuine Ray-Ban screws to your order.
Can I fit it myself, or can you fit it for me?
Both. It's a quick fix with a precision screwdriver if you'd like to do it yourself. If you'd rather we handled it, choose “Sunglasses UK to fit” (+£10) in the buy box — we'll email a Royal Mail returns label, fit the bar in our UK lab and post your frame back.
How quickly does it ship?

What if I order the wrong size?
Not a problem — this part is stocked rather than custom-made, so email us and we'll swap it for the other size.
