Set of 4 Transparent Frameless Weather Stripping Silicone Seal Sweep for Door Window - Each size(inch) : 39(L) X 1.375(W)

I use it under my doors since I close the guest rooms in the winter when the wood stove is burning. It’s like arctic air blowing under the doors. Doubted it would hold because nothing else had plus my two cats shoving toys under the door then pawing to retrieve don’t lend to durability. I looked the other day expecting the corners at least to have pulled free but it’s still hanging in there. For me, it would be worth a new batch every year but I’m heading into winter two with the same strips on the doors

The tape is super solid and the quality of the material is good. I'm not really sure how much of insulation this tape is really doing but for a place that has lots of window leak I'd recommend it.

Fair warning - I didn't use this product entirely as intended. I bought this it lengthen the flap on a dog door. It mostly works, but doesn't stand up to weather. I had to reinforce it with duct tape. I tried it on a wooden mail slot as well, and it doesn't stay stuck to the rough wood.

Used this to replace a torn shower door bottom seal. Perfect fit and I have 3 spares. Great solution.

put this on the bottom of my shower door, because there was a small gap. This works great and because its clear, you don't see it.

Great quality and price
