Bifold Shower Seal - Wide 10mm T-Head, 12mm Tall, Seals 7-12mm Gaps

What this seal is

A clear channel seal with the widest T-head in our bifold range: 10mm across, with a 12mm tall body sealing gaps of 7–12mm. It is made for frames with an unusually wide channel slot that smaller T-heads simply fall out of.

Fit it horizontally under the bottom rail of a folding bath screen or shower door, or vertically between the glass and the wall — the T-head slides into the channel with no adhesive and the soft blade closes the gap below.

Choose your length

Available in 900mm and 2000mm lengths. Order the length at or above your door width and trim it down with scissors, or use our custom cutting service (please note custom-cut items are non-returnable).

Specification

Why fit this seal

Stays put in wide channels. If replacement seals keep dropping out of your frame, the slot is probably wider than standard — this 10mm T-head fills it and holds.

Stops leaks along the bottom of the door. A worn or missing bifold seal lets water track under the door onto the bathroom floor; a fresh seal protects flooring and skirting.

No adhesive, no mess. The T-head slides into the existing channel and grips by itself, with no residue at the next change.

Cut to fit at home. The soft PVC cuts cleanly with a good pair of scissors, so one length covers any door up to 2000mm wide.

Fitting in three steps

1. Measure. Check your channel slot is around 10mm wide, and that the gap you need to close is between 7mm and 12mm.

2. Choose. Pick the 900mm or 2000mm length — whichever is at or above your door width.

3. Fit. Remove the old seal and clean the wide channel, cut the new seal to the door’s width, then slide the T-head along the channel until seated.

Not sure it fits?

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