Shower Screen Seal - 4-6mm Glass, Twin Fin, 12mm Tall
Price shown updates with the option you pick.
What this seal is
A clear shower screen seal for 4–6mm glass with a single flexible side fin. The rigid PVC U-channel simply pushes onto the edge of the glass — no adhesive needed — and comfortably grips 4mm, 5mm or 6mm glass, while the side fin closes the gap against the adjacent surface.
Because the fin sits to the side, this seal is most often used vertically on the upright edge of the glass, commonly in conjunction with a similar-shaped seal on the opposite panel. It can also be fitted along the bottom horizontal section of a bath screen or shower door.
Choose your length
Available in 800mm, 900mm, 1400mm or 2000mm lengths and easily cut down at home. If your glass edge sits between two sizes, order the next length up and trim it — or use our custom cutting service and it arrives ready to fit.

Why fit this seal
Stops leaks at the door edge. A worn, discoloured or missing vertical seal lets water escape every time you shower — replacing it takes minutes and protects flooring and plaster from long-term damage.
No adhesive, no mess. The U-channel grips 4–6mm glass on its own — it slides straight on and can be removed or repositioned without leaving residue.
Barely visible once fitted. The clear PVC blends into the glass, keeping your enclosure looking clean and bright.
UK stock, fast dispatch. Order before 2pm and your seal is dispatched the same working day.
Fitting in three steps
1. Measure. Check your glass is 4–6mm thick and measure the edge you need to seal.
2. Choose. Pick the nearest length at or above your measurement.
3. Fit. Remove the old seal, trim the new one to length if needed, then push the channel onto the edge of the glass with the fin facing the gap. No tools, no adhesive, no drying time.
Not sure it fits?
Email a photo of your old seal or your measurements to sales@industrial-polymers.co.uk and our UK team will confirm the right profile and size before you order — usually the same working day.
