Will the F456S2535 Solve Your "Impossible" Gap Problem?
The SIMBA 35mm 'Gap-Jumper' is our specialist solution for situations where standard seals simply can't cope. If you have a massive clearance—up to 67mm when the fins are angled—this is the professional’s choice for restoring a dry bathroom floor.
Specifically engineered with a narrowed U-channel to 'bite' onto 4mm, 5mm, and 6mm glass. This prevents the heavy 35mm fin from causing the seal to wobble or slide off thinner screens.
With a massive 35mm reach per seal, this pair provides extensive coverage. Whether your tray has dropped significantly or the screen was installed high, these fins reach out to trap every drop of water.
This specialist model is the flagship of our F shape shower door seals collection—the UK’s most comprehensive range for bespoke shower fixes.
Why Choose the 35mm Extra-Long 'Slim-Fit' F Seal?
Specifically engineered for lightweight frames that require industrial-strength water protection.
The 35mm fin is the longest 'F' profile available for 4-6mm glass, acting as a soft, flexible barrier across huge gaps.
Despite its size, the rigid 'F' channel clips onto the glass edge with a high-tension fit. No glue or curing time required.
Formulated with premium UV stabilisers to resist the brittle yellowing typical of cheap 'universal' imports.
Infused with anti-fungal agents to prevent black mould from taking hold in the flexible fin joints.

Care & Installation Tips
Ensure a better fit and longer-lasting clarity.
✓ 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.
