Angled-Pile Weatherstrip

Pile set at an angle to the backing rather than square to it. In a retractable screen track the leaning filament reaches into the mesh instead of stopping at it, so the edge stays closed while the screen travels. We run this from 30° to 90°, built to your drawing.

Made to order Backing width, pile height, fin, colour — all specified by you. Standard sizes run on existing tooling; non-standard is the larger half of what we run.

Also called angled pile, angle pile weatherstrip, angled brush strip, retractable screen pile, screen track brush, angled weatherpile, slanted pile weatherstrip and insect screen edge brush.

Made to your channel, not ours

The two dimensions called out on that drawing are both yours to set. The two things most often changed on this line are the pile angle and the pile height.

Same terms. Post us 50 mm of the extrusion and we cut to it; the die stays reserved to your part number

Send a drawing, and post us 50 mm or more of the extrusion — we match the backing to the section itself. Any tooling we have to cut is ours to pay for, and it stays reserved to your part number. Large suppliers sell from a fixed catalogue and treat a non-standard size as an inconvenience. We were built the other way round.

Why this construction

A square-set pile meets the screen mesh face on and stops there — the gap at the edge of the cloth stays open. Angling the filament lets it enter that gap and stay in it while the screen rolls up and down, which is what keeps leaves and insects out at the edge. It is also what holds a soft mesh in line: without pile in both side tracks the cloth has nothing to run against.

How to specify it

Four things get you a quote and a matched sample. If you only have two of them, send two.

  1. The backing width you runGive it however you have it — .270″, 7 mm, or the die drawing. We convert.
  2. The pile height you needOr the gap you are sealing, if the height was never specified.
  3. Fin or no finAnd silicone treatment or not. These are the two that change the part number.
  4. Annual volume and colourRough is fine. It decides the run size, not the price of the sample.
