As an EU customer I was disappointed with paying 15 euro extra at customs/DPD. But it is a good seal. 60 euro in total after customs was steep.

Check Before You Buy
This seal is suitable if:
- Your glass is 8mm, 9mm or 10mm thick.
- You have a frameless sliding shower door with two overlapping glass panels.
- The measured gap between the overlapping panels is approximately 23mm–38mm when both strips are fitted as a pair.
-
You need a large 20mm fin for a wider sliding door overlap, but not the maximum 35mm fin size.
- The 15mm fin option is not large enough for your measured gap.
- You want to reduce water escaping through a wider side overlap where the sliding panels pass each other.
- Your required length is 2000mm or less.
- You are replacing old, yellowed, cracked or loose F-Type overlap seals on a sliding shower door.
Choose another seal if:
- Your glass is thinner than 8mm or thicker than 10mm.
- The gap between the glass panels is smaller than 23mm or larger than 38mm when fitting as a pair.
- You only want to fit one strip for a 23mm–38mm gap.
- You need a smaller fin for a tighter overlap gap.
-
Your gap is wider than 38mm and may require the 35mm fin option.
- You need a magnetic closing seal, bottom seal, drip seal, threshold seal, guide rail seal or track seal.
- Your shower door is hinged, framed, or has a thick metal edge trim.

FAQ
1. What glass thickness does this seal fit?
It fits 8mm, 9mm and 10mm frameless glass.
2. What gap is the 20mm fin suitable for?
When fitted as a pair, this seal suits wider overlap gaps of approximately 23mm–38mm between two sliding glass panels.
3. Is this the largest fin size?
No. The F810S20 is a large fin option, but a 35mm fin version is also available for extra-wide overlap gaps.
4. Can I use just one strip?
Single-strip use is not recommended for a 23mm–38mm gap. For this gap range, fit both strips as a pair.
5. How do I cut this seal to size?
Use your old seal as a cutting guide, or hold the new seal against the shower door and mark the required length before cutting.
Suitable Applications
The F810S20 Standard 20mm Fin F-Type Shower Seal Pair is a large fin option for frameless sliding shower doors with 8mm, 9mm or 10mm glass.
It is designed for wider sliding door overlaps where the measured gap is approximately 23mm–38mm when both strips are fitted as a pair. This makes it a suitable choice when the 15mm fin option is not enough, but the maximum 35mm fin size may not be required.
Fit the seals to the overlapping glass edges where the two sliding panels pass each other. The longer 20mm flexible fin helps reduce water escaping through a wider side overlap while keeping the seal suitable for compatible frameless glass.
To check the size, measure the space between the two overlapping glass panels at the point where they pass each other.
This seal is not intended for magnetic door closing edges, bottom shower door seals, drip seals, guide rail seals, framed metal edges, hinged doors, or glass thinner than 8mm or thicker than 10mm. It is also not the best choice for smaller overlap gaps where a shorter fin would sit more neatly.
