Installation FAQ

Why Choose the VC456 Offset Seal? +

Unlike standard centered seals, the VC456 features an Offset Fin that extends from the edge of the profile.

  • Solve Hardware Obstructions: Perfect for doors with raised aluminum thresholds. The offset fin glides alongside the hardware rather than being crushed against it.
  • Triangular Support Structure: Reinforced by a discreet triangular guide to maintain shape while remaining soft on feet.
  • A Softer Alternative: Offers a superior balance of water retention and ease of use.

Installation Tip: Aim for a 1-5mm overlap between the soft fin and your threshold for the smoothest operation.

Will this seal fit my 4mm, 5mm, or 6mm glass? +
Yes. The VC456 is engineered with a tapered U-channel and an increased 11mm profile height. This "deep grip" design ensures the seal remains securely attached to the glass even under daily use.
Will it stay clear or turn yellow? +
We use high-grade PVC infused with anti-fungal agents and UV stabilizers. This formula is designed to resist environmental aging and significantly delay the yellowing process.

Care & Installation Tips

4–6mm Offset Shower Door Bottom Seal – 15–18mm Gap | VC456 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.
