Check Before You Buy

This seal is suitable if:

  • Your shower glass is 4mm, 5mm or 6mm thick.
  • You need an F-shaped side seal between adjoining glass panels.
  • Your glass gap is around 18–25mm.
  • You need a 15mm flexible fin to create a wider side overlap.
  • Your required finished length is 2000mm or less.

Choose another seal if:

  • Your glass thickness is outside 4–6mm.
  • Your glass gap is clearly outside the recommended range.
  • You need a much wider adjustable fin.
  • You need a bottom, magnetic or framed-track seal.

Product Details

F456S15 is a clear F-shaped shower door side seal for 4–6mm glass, intended for wider spaces between neighbouring glass panels.

The 15mm flexible fin provides enough reach for gaps of around 18–25mm, helping form an overlapping barrier between the panels while remaining flexible as the door moves.

The fixed fin requires no width adjustment. Check the glass thickness and gap before ordering, push the clear channel onto the straight glass edge, then cut the 2000mm strip to the required height.

No adhesive is required on compatible glass.
