Frequently Asked Questions

Why S456DTL is better for sliding doors? ▼
Standard bottom shower door seals often jam sliding mechanisms. The S456DTL Gasket is a low-profile specialist, ensuring a smooth, frictionless glide without adding bulk.
Use on frameless door with no gap? ▼
Absolutely. If your door has zero clearance, this seal provides a watertight "flush" seal. It’s the ultimate minimalist solution.

Why Choose the SIMBA S456DTL?

  • Zero-Drag Performance: Engineered specifically to prevent "door-drag" on bottom-track systems.
  • Snap-Fit Installation: The rigid U-channel grips glass securely—no silicone or tape required.
  • Crystal Clear: Anti-UV PVC ensures it remains discrete and won't yellow over time.
  • Value Bundle: Includes a Testing Kit of 3 additional profiles to ensure 100% water protection.

✓ 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.
