Bifold Shower Door Upright Seal for M2 Doors - Clear, 1000mm & 2000mm

What this seal is

A clear, soft-PVC upright seal for bi-folding shower doors — most commonly fitted to M2 bi-fold doors, vertically on the left and right sides of the door. The compact hooked body clips into the door frame’s vertical channel, and the long angled fin presses gently against the neighbouring glass panel to close the gap and keep water inside the enclosure.

It slides into the existing channel your old seal came out of — no adhesive, no tools — and the soft, translucent PVC is barely noticeable once fitted.

How to check it fits your door

The first photo in the gallery shows the exact cross-section — a squarish body with two hooked flanges and a single diagonal fin. Remove your old seal and compare its end profile to that cutaway. If your old seal has the same hooked body and fin, this is the right replacement.

Specification

Why fit this seal

Stops leaks at the door edges. A hardened or split upright seal is a common cause of water escaping down the sides of a bi-fold door. A fresh fin closes the gap against the neighbouring panel and keeps the water in the enclosure.

No adhesive, no mess. The hooked body simply feeds into the channel — no glue, no drilling — and slides out again just as easily when it’s next due a change.

Easy to cut at home. The soft PVC trims cleanly with household scissors, so ordering the next length up and cutting down to your door height takes seconds.

UK stock, fast dispatch. Held in stock in the UK, so a leaking bi-fold door is sorted in days, not weeks.

Fitting in three steps

1. Measure. Measure the height of the door upright, and check your old seal’s profile against the cutaway photo in the gallery.

2. Choose. Pick 1000mm or 2000mm — whichever is at or above your door height — or select a Custom Cut option and tell us your exact length.

3. Fit. Slide the old seal out and wipe the channel clean of soap residue and limescale, trim the new seal to length, then feed the hooked body in from one end with the fin facing the adjacent glass panel.

Not sure it fits?

Email a photo of your old seal’s end profile 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.
