Shower Screen Seal - 4-6mm Glass, Arched Fin for Thresholds

What this seal is

A clear shower screen seal for 4–6mm glass with a rigid arched fin. The rigid PVC U-section pushes straight onto the edge of the glass and grips it comfortably with no adhesive, while the arched fin sweeps down to close off the space beneath the door.

This profile is the one to choose when there is only a very small gap under the door, or a threshold that the door passes over — the arched fin rides over the threshold while still deflecting water back into the enclosure.

Specification

Why fit this seal

Stops leaks and protects your floor. Even a very small gap under a shower door lets water creep out onto flooring and skirting shower after shower. Replacing a worn or missing seal takes minutes and prevents long-term water damage.

Made for thresholds. Where the door passes over a threshold or upstand, a deep flexible blade would drag and catch — the rigid arched fin clears it cleanly while still turning water back into the enclosure.

No adhesive, no mess. The U-section grips 4–6mm glass on its own — it slides straight onto the edge and can be removed or repositioned without leaving any residue.

Cut to fit at home. Order the next length up and trim it down for a perfect edge-to-edge fit, or use our custom cutting service and it arrives ready to fit.

Fitting in three steps

1. Measure. Check your glass is 4–6mm thick, measure the width of the door edge, and check the small gap or threshold the door passes over.

2. Choose. Pick the nearest length at or above your measurement — 800mm, 900mm, 1400mm or 2000mm.

3. Fit. Trim to length if needed, then push the U-section onto the bottom edge of the glass so the arched fin faces down into the enclosure. No tools, no adhesive, no drying time.

Not sure it fits?
