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 34mm–67mm when both strips are fitted as a pair.
  • You need the maximum 35mm fin size for an extra-wide sliding door overlap.
  • Smaller fin sizes such as 15mm or 20mm do not provide enough coverage for your measured gap.
  • You want to reduce water escaping through a large side overlap where the sliding panels pass each other.
  • Your required length is 2000mm or less.
  • You are replacing old, yellowed, cracked or loose long-fin 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 34mm when fitting as a pair.
  • Your gap is around 34mm–38mm and a 20mm fin may provide a neater fit.
  • You only want to fit one strip for a 34mm–67mm gap.
  • You need a smaller fin for a standard or tighter sliding door overlap.
  • 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 35mm fin suitable for?

When fitted as a pair, this seal suits extra-wide overlap gaps of approximately 34mm–67mm between two sliding glass panels.

3. Why does it need to be fitted as a pair?

The 34mm–67mm gap range applies when one seal is fitted to each overlapping glass edge. A single strip will not provide the intended coverage for this gap range.

4. Is this the largest fin size in this range?

Yes. The F810S2535 has a 35mm fin and is the largest fin option in this F-Type overlap seal range.

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 F810S2535 Standard 35mm Fin F-Type Shower Seal Pair is the maximum fin-size option for frameless sliding shower doors with 8mm, 9mm or 10mm glass.

It is designed for extra-wide sliding door overlaps where smaller F-Type seals may leave too much of the side gap exposed. When both strips are fitted as a pair, this seal suits measured overlap gaps of approximately 34mm–67mm.

The 34mm–67mm gap range applies when one seal is fitted to each overlapping glass edge. This paired long-fin setup helps improve coverage across large side overlap spaces where standard fin sizes may not be sufficient.

Choose this 35mm fin version when your measured overlap gap is beyond the F810S20 range and you need the largest fin coverage in this series. If your gap is close to 34mm–38mm, compare with F810S20 first, as the 20mm fin may sit more neatly on some doors.

Fit the seals to the overlapping glass edges where the two sliding panels pass each other. The extra-long 35mm flexible fin helps reduce water escaping through a larger side overlap while still using a simple push-fit installation on 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.

F Shape Vertical Shower Door Seal for 8-10mm Glass 35mm Fin F810S2535 Installation Guide - Simba Anti-Mould Shower Seal

DO’S

  • Direct Press: Fit by pressing directly onto the glass edge to protect the surface.
  • Deep Clean: Remove all UK hard-water limescale before installation.
  • Sharp Tools: Use garden pruners for a clean, professional finish.
  • Daily Rinse: Simply wash away soap suds after your shower.

DON’TS

  • No Sliding: Never slide the seal along the glass; this risks scratching.
  • No Extreme Heat: Avoid water >70°C or hair dryers to prevent warping.
  • No Soapy Water: Do not use lubricants—they accelerate mould growth.
  • No Harsh Chemicals: Avoid bleach or acidic cleaners on the seal.
