Bifold Shower Seal - 6mm T-Head, 9mm Tall, Seals 4-9mm Gaps

What this seal is

A compact clear channel seal for bifold shower doors and bath screens, with a 6mm T-head and a 9mm overall height that seals gaps of 4mm to 9mm. The T-head slots into the aluminium or plastic channel of your door frame — no adhesive required — and the soft flexible body closes the gap below.

It sits between our low 4–6mm and taller 7–12mm profiles on the same 6mm T-head, and fits horizontally under the bottom rail or vertically between the glass and the wall.

How to check it's the right size

Your frame slot should take a 6mm T-head, and the gap you need to close should be between 4mm and 9mm. We stock several heights on the same 6mm T-head, so compare the cutaway in the first photo with the end of your old seal — if your gap sits at the edge of two sizes, the flexible body compresses, so choose the taller profile for a tighter seal.

Specification

Why fit this seal

Stops leaks at the door. A worn or shrunken bifold seal is a common cause of water escaping onto the bathroom floor. The soft body compresses across gaps of 4–9mm to keep the water where it belongs.

No adhesive, no mess. The T-head simply slides along the frame channel — nothing to glue, screw or drill, and it comes out just as cleanly when next due a change.

Barely visible once fitted. The clear translucent PVC blends into the frame and glass rather than yellowing on show.

Cut to fit at home. Trim it to your door's width with ordinary scissors, or use our custom cutting service and it arrives ready to fit.

Fitting in three steps

1. Measure. Check your frame slot takes a 6mm T-head, measure the gap to close (4–9mm suits this profile) and measure the width of your door.

2. Choose. Pick 1000mm or 2000mm — whichever is at or above your measurement — or add the custom cutting service.

3. Fit. Slide the old seal out and clean the channel, cut the new seal to the door's width, then feed the T-head in at one end and slide it across 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 height before you order — usually the same working day.
