Magnetic Shower Door Seals for 4-6mm Glass - 1 Pair, Spans 20mm

What this seal is

A pair of clear magnetic seals for shower doors with 4–6mm glass, used vertically at 180° — most often on quadrant enclosures, though some bath screens and other doors use them too. Each rigid PVC U-section pushes onto the edge of the glass with no adhesive, and carries a magnetic strip covered in white plastic to match the rest of your enclosure.

When the door closes, the two magnetic strips pull together to hold it firmly shut while you shower — yet it still opens easily when you're finished.

Will these suit my door?

On sliding doors, these seals are suitable as long as the gap is no greater than 20mm when the doors are closed. On hinged or pivoting doors, the gap needs to be exactly 20mm — otherwise the two magnetic strips won't quite line up and the seals may not function as intended.

Specification

Why fit this seal

Holds the door shut. Tired magnets let the door drift open mid-shower — a fresh magnetic pair pulls it closed and keeps the water in the enclosure.

No adhesive, no mess. Each channel grips 4–6mm glass on its own, pushing straight onto the edge and coming off cleanly if you ever need to replace it.

Matches your enclosure. The white plastic covering over the magnet blends with your enclosure, while the clear channel disappears against the glass.

Two lengths to suit tall doors. Choose 2000mm or 2500mm and trim down at home, or use our custom cutting service and they arrive ready to fit.

Fitting in three steps

1. Measure. Check your glass is 4–6mm thick and measure the gap between the closing edges — no more than 20mm for sliding doors, exactly 20mm for hinged or pivoting doors.

2. Choose. Pick the 2000mm or 2500mm pair to suit your door height; trim at home or add custom cutting.

3. Fit. Push one channel onto each meeting edge so the magnetic faces line up when the door closes. No tools, no adhesive, no drying time.
