Magnetic Shower Seals - 4-6mm Glass, Spans 18-20mm - 1 Pair

What these seals are

A pair of clear magnetic seals for shower doors with 4–6mm glass. Each seal has a rigid PVC U-section that simply pushes onto the edge of the glass — no adhesive, no screws, no drilling — and grips glass of 4mm, 5mm or 6mm on its own. Built into each seal is a magnetic strip covered in white plastic, so the two closing edges pull together and hold the door shut while you shower, yet still open easily when you're finished.

Fitted as a pair on the vertical closing edges of the door and adjacent panel, they replace the tired, discoloured magnetic strips that stop a door closing crisply and let water escape at the join.

Specification

Why fit these seals

Holds the door shut. The magnetic strips pull the closing edges together every time, so the door can't drift open mid-shower and let water escape.

Seals the closing edge. The two profiles meet along the full height of the door, closing the join against spray as well as holding it closed.

No adhesive, no mess. Each channel grips 4–6mm glass on its own — the seals push straight on and come off without leaving residue.

UK stock, fast dispatch. Held in stock in the UK and dispatched same day when you order before 2pm.

Fitting in three steps

1. Measure. Check your glass is 4–6mm thick and measure the height of the two closing edges.

2. Choose. The pair come in 2000mm lengths ready to cut down — or use our custom cutting service and they arrive ready to fit.

3. Fit. Remove the old seals, trim the new pair to length if needed, then push one channel onto each closing edge so the magnetic strips face each other and pull the door closed.

Not sure they fit?

Email a photo of your old seals or your measurements to sales@industrial-polymers.co.uk and our UK team will confirm the right profile before you order — usually the same working day.
