Multi-Fit Bifold Seal - 5mm, 7mm & 10mm T-Heads, Trims to Any Gap up to 32mm

What this seal is

The multi-fit option in our bifold range: one clear soft-PVC extrusion carrying three T ridges — 5mm, 7mm and 10mm — so one seal fits most channel widths. The 32mm body is designed to be trimmed down, sealing any gap from 1mm to 32mm. If you're not certain which single-size seal your door takes, this is the safe choice.

The matching T ridge slides into the aluminium or plastic channel on your door — no adhesive — and the seal runs horizontally along the bottom rail or vertically between glass and wall.

How to check it fits your door

Measure the slot in your channel — if it's roughly 5mm, 7mm or 10mm wide, one of the three ridges will fit. Then measure the gap you need to close and trim the 32mm body down to suit with scissors. If your gap sits between measurements, trim slightly long — the soft PVC compresses for a tighter seal.

Specification

Why fit this seal

One seal, most doors. Three T-head sizes on a single extrusion mean you don't need to identify your exact channel width before ordering — a 5mm, 7mm or 10mm slot is covered.

Any gap up to 32mm. Rather than hunting for a seal with exactly the right blade depth, you cut this one down to precisely the gap under or beside your door.

No-mess fitting. The ridge slides into the existing channel — no adhesive, no drilling — and swaps out again in minutes when it eventually wears.

UK stock, fast dispatch. Order before 2pm and your seal is dispatched the same day from our UK warehouse.

Fitting in three steps

1. Measure. Remove the old seal, clean the channel, and measure both the channel slot and the gap you need to close.

2. Choose. Pick the 1000mm or 2000mm length, then trim the body height and length to suit with scissors.

3. Fit. Slide the matching T ridge along the channel until the seal is seated flush across the full width.
