Bifold Shower Seal - 7mm T-Head, 19mm Tall, Seals 12-19mm Gaps
Price shown updates with the option you pick.
What this seal is
The tallest of our 7mm T-head channel seals: a clear seal with a 19mm-tall body that closes large gaps of 12–19mm under bifold shower doors and bath screens. The T-shaped head slots into the aluminium or plastic channel in your door frame — no adhesive required.
It fits horizontally under the bottom rail of the door, and works just as well vertically between the glass and the wall.
Choose your length
Two lengths are available — 900mm and 2000mm. Pick the length at or just above the width of your door; the soft PVC cuts easily with scissors, or add our custom cutting service and it arrives ready to fit (custom-cut items are non-returnable). If your gap is smaller than 12mm, our 7mm, 8mm, 10mm or 12mm-high 7mm T-head profiles will suit better.

Why fit this seal
Closes large gaps smaller seals cannot. With a 19mm body covering 12–19mm gaps, this profile seals doors that sit well above the tray and would otherwise let water pour straight out.
No adhesive, no mess. The T-head simply slides along the existing channel in the frame — nothing to glue, and it slides back out when it is next due a refresh.
Cuts with scissors. The soft PVC trims to the exact width of your door in seconds — no saws or special tools.
Easy like-for-like replacement. Match the 7mm T-head and the 19mm height, compare the cutaway photo with your old seal, and the new one drops straight into place.
Fitting in three steps
1. Measure. Check your channel slot suits a 7mm T-head and that your gap is 12–19mm.
2. Choose. Pick 900mm or 2000mm at or above your door width, and compare the cutaway photo with the end of your old seal.
3. Fit. Slide the old seal out, clean the channel, cut the new seal to width, then feed the T-head in at one end and slide it across.
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.
