Check Before You Buy

Note: The slot may look slightly smaller in the drawing, but this helps the seal grip the glass securely once fitted. Please use the glass thickness listed above as your main guide.

This seal is suitable if:

  • Your glass is 4mm, 5mm or 6mm thick.
  • You need a bottom seal for a straight shower door or screen.

FAQ

1. What glass thickness does S456DTL fit?

It fits 4mm, 5mm and 6mm frameless glass.

2. Is this suitable for 8mm or 10mm glass?

No. This version is only for 4–6mm glass.

3. What bottom gap is it suitable for?

It is best for very small bottom gaps, around 0–3mm.

4. Which way should the rigid side fin face?

The rigid side fin should face inside the shower area.

5. Is this a soft flexible bottom seal?

No. This is a rigid profile with a side fin, designed for small bottom gaps.

Suitable Applications

S456DTL is designed for thin frameless shower glass, including 4mm, 5mm and 6mm panels.

It works best where the bottom of the glass sits close to the tray, with little or no gap. The rigid side fin should face inside the shower area to help guide water back in.

This seal is supplied as one 950mm clear strip and can be cut shorter if required.

It is not suitable for 8mm or 10mm glass, curved door bottoms, framed doors, large bottom gaps, magnetic seals, guide rails or track seals.

4–6mm Glass Shower Door Bottom Seal with Side Fin Small Gap Seal S456DTL 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.
