Why Choose the S810DTL Bottom Seal? VIEW DETAILS ▼

 

  •   Finding the right fit for thick glass can be tricky. The S810DTL solves this by offering a universal fit for 8mm, 9mm, and 10mm panels. Unlike standard strips, its reinforced U-channel grips heavy glass securely, while the extended side fins bridge gaps up to 5mm. Whether you have a pivot, sliding, or hinged shower, this heavy-duty gasket ensures a watertight seal without compromising on clarity.
  • The S810DTL is manufactured using the exact same cold-resistant formula as our award-winning SL810DTL. It passed the identical -39.5°C Lab Test, ensuring flexibility and durability even in freezing UK winters.
💡 SIMBA Pro-Tip: S810DTL ADVICE ▼

The S810DTL is our 'secret weapon' for designer sliding doors where the gap is so small it’s almost invisible. If you’ve tried a standard 'drip-fin' seal and found your door is suddenly impossible to push, it’s because the seal is acting like a brake. The S810DTL moves the protection to the side, allowing for a 100% watertight seal with absolute zero friction. It’s the ultimate fix for high-spec, low-clearance enclosures.

✓ 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.
