Clear Multi-Fit Bifold Seal - 4mm, 6mm & 8mm T-Heads, Trims to 32mm

What this seal is

A clear multi-fit seal for bifold shower doors: one soft-PVC extrusion carries three T-head sizes — 4mm, 6mm and 8mm — and a 32mm body that you trim down to suit your gap. Cut away the parts you don't need and this single seal covers most bifold doors and channel-fitted screens.

The chosen T-head simply slots into the aluminium or plastic channel on your door frame — no adhesive required — while the trimmed body closes gaps from 1mm right up to 32mm. It's also available in white, and in a 5/7/10mm T-head combination if your channel is a different size.

Which T-head do I need?

Measure the slot in your channel — if it's 4mm, 6mm or 8mm wide, this seal fits. Then measure the gap below the door and trim the 32mm body to suit. Trim a little at a time and re-test the fit — it's easy to take more off, impossible to put it back.

Specification

Why fit this seal

One seal, most bifold doors. With three T-head sizes on a single extrusion and a trim-to-fit body, you don't need to identify your exact profile before ordering.

Stops leaks under the door. A perished or shrunken bifold seal is the usual cause of water creeping out under the door — a fresh blade trimmed to your gap keeps it in the tray.

No adhesive, no mess. The T-head slots into your existing channel and can be replaced again in future without leaving any residue.

Cuts with scissors. The soft PVC trims cleanly at home — both to length and to gap height.

Fitting in three steps

1. Measure. Measure your channel slot (4mm, 6mm or 8mm) and the gap beneath the door.

2. Trim. Cut off the T-heads you don't need, trim the body to your gap and cut the seal to the width of the door.

3. Fit. Slide the matching T-head along the channel until the seal runs the full width of the door.
