WRSSilverline Offset T-Slot Foam Seal Weather Stripping-White, 24 Ft Roll

Outside noise is gone along with draft. Not super cheap but worth the money. Excellent product

Get ready for a fight. The likely problem (since it measured right) is the dirt that builds up in the track. I suggest cleaning them spraying the track AND product with WD40. Unless you have a couple of hours & knuckles to spare. Glad it's over. Did about 10.

Exactly what I was looking for...

I had difficulty identifying the t-slot weather stripping from my windows, the team and WHD fixed me up quickly and the product was as advertised. A bit difficult to install, until I used some dove soap (bar) to lube the window slot. Well done WHD!

Good fit to stop wind, rain and critters

We have a 17 year old house with vinyl windows. The window frames and glass are in great condition but the weatherseal felt strips and the bottom seal were compressed and no longer sealed well. I called a local glass company to see if they would replace the seals but they said they have the seals but did not replace them. So I looked on Amazon, measured the existing seals for height and width and ordered a small amount to see how hard it would be for me to replace them. Did it first on a small bathroom window. Removed the bottom sliding section, set it on a table with some towels underneath to protect against breakage. Removed the seals one by one and replaced them one by one and what a difference. Yesterday completed all 3 small windows and the 9 3.0x5.0 windows. The house is not only tighter but quieter and took about 5 hours and in total spent $156.00. I would highly recommend doing this and buying for this vendor. Great prices and very quick delivery
