Magnetic Shower Door Seals for 4-6mm Glass - 1 Pair, Spans 30mm

What this seal is

A pair of clear magnetic seals for shower doors with 4–6mm glass, fitted vertically and usable at either 135° or 180° — most often on quadrant enclosures, though some bath screens and other doors use them too. Each rigid PVC U-section pushes straight 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 30mm when the doors are closed. On hinged or pivoting doors, the gap needs to be exactly 30mm — 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 inside the enclosure.

Spans a wide 30mm gap. This profile reaches further across the closing gap than most magnetic pairs, so it suits quadrants and offset doors that narrower seals cannot bridge.

No adhesive, no mess. Each channel grips 4–6mm glass on its own, pushing 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 frame, while the clear channel disappears against the glass.

Fitting in three steps

1. Measure. Check your glass is 4–6mm thick and measure the gap between the closing edges — no more than 30mm on sliding doors, exactly 30mm on hinged or pivoting doors.

2. Trim. Cut each 2000mm length down to your door height with a good pair of scissors, or add our custom cutting service and they arrive ready to fit.

3. Fit. Push one channel onto each meeting edge from the bottom, working upwards — never slide them along the glass. Line the magnetic faces up so they meet when the door closes. No tools, no adhesive, no drying time.
