TMH Premium Pure Silicone Kerf Weather Stripping Door Seal, Window and Door Frame Sealer Bulb/Ring Shape, Black - 20 Feet

This is great weatherstrip but it took me a little bit to learn the trick for installing it. The same pliancy that enables it to seal so well creates a difficult install at first. The kerf on my door was poorly set up and ended up hiding a ledge that was slightly recessed behind the bulb. This made it difficult to align the tab with the kerf. The solution was to hold a rigid piece of material that matched the ledge thickness ( in my case 1/4" thick bar stock) against the jamb so the tab had a straight path into the kerf. The other trick is to wet the kerf and the rubber with water. Then the seal can be inserted with a 1" putty knife or something similar (do not use a putty chisel) by compressing the bulb in order to press against the upper edge of the tab strip. Then just work your way along the length of the seal. It stays where you put it, remains pliant in cold weather, and seals well. It is easy to cut to length with household scissors.

Wish I’d paid attention to other reviews but hubris got the better of me. I’ve installed multiple doors and replaced all kinds of weather stripping so I thought I could trouble shoot this. No such luckThe material is soft, so soft that it tears easily with a putty knife or wood shim trying to help it (yes after lubrication with soap and water) get into the groove. Save your money and look for an alternative

If this was easier to install it would get SIX stars... and I'm a contractor.The product itself is great; super flexible so the door can squish it closed easily, seals almost a half-inch gap, yet bounces back to shape. Yay silicon.Unfortunately, I agree with other reviewers that it's hell to install. Definitely not a homeowner "pull out the old, slide in the new" product.In a nutshell, most door kerfs need to be widened to a full 1/8 inch, then the product needs to be stretched with two hands in short sections WHILE sliding into kerf back and forth. After entire length is in, still needs adjustment and sometimes pressure from a wide-blade plater knife... which can cut the slime kerf-retaining wings.I'm clever, a pro, and have good equipment... still took an hour!Now that its in, great product.

Would be a 5 star if the kerf was of a more durable material other than silicone. Tears easily and is slow to install since it tears with moderate force applied.

I was excited to find this as I have a round top front door and can never find suitable weather-stripping to fit my door at the big box stores. This looks like it was going to work for the kerf cut on my door and was the correct size. The issue is there is no rigidity to the kerf so I was unable to get it in the kerf cut. Wanted to love, but ended up returning. Return process was easy.

What differentiates this weatherstripping from others I have used is the stiffer material used on the barb flange, making it more secure and easier to install.

Easy installation, good insulation

I have been having a hell of a time finding kerf seal that will fit the front door without stopping it from closing. This looked promising as it is a soft silicon tube that should compress. The problem is it has no spine on the kerf part so there is literally no way to insert it into the kerf of the jamb.
