Ease Of Use

Has a surface that provides a secure bond.

Prevents cold air and dust from entering.

Includes multiple easy-to-read directions.

I received product reimbursement in exchange for my honest review. this silicone gasket was super easy to install. I was able to cut it with a regular scissor, and apply it no problem to all three sides of my door frame. it does have a very strong rubber smell, but that dissipates within a few hours of applying it. so far it's been great at keeping out drafts.

Great for keeping out drafts

I received product reimbursement in exchange for my honest review.  I've used this before and it's just as easy as I remember.  The adhesive is really sticky and holds onto the surface you put it on.  Mine hasn't come off yet, not has it peeled away any.  It's a little smelly when you open it but that disappears and it's only from the glue.

Still holding tight!

I received product reimbursement in exchange for my honest review.

This door seal really is all purpose. I like that it is self adhesive, and can be used on windows or doors. It really does a great job at insulating my home, which I really appreciate during the winter months.

Perfect

I received product reimbursement in exchange for my honest review. I like that there are clear and many instructions on the packaging as I usually don't know what I'm doing with home improvement projects. I also love that it is a self-adhesive, it's one less thing to worry about. I like that it is smoke tested as safety is important when I have little ones.

Clear and easy to use

I received product reimbursement in exchange for my honest review. this is the silicone gasket all purpose used to seal doors and windows:-) this is a 20 ft long strip and has double stick backing on it as so you can apply to any purpose as needed. good for both doors and windows is very thin as to not make it too bulky to make the door unclosable:-)

Very thin and good for any purpose:)

I received product reimbursement in exchange for my honest review. I'm really glad there are many instructions on the packaging. If you are installing on a door, you are not supposed to install this in one whole piece. You cut into three smaller pieces. It is self adhesive so it was very simple and straight forward to stick. It seems like it's made out of durable rubber so it will last a long time. This will keep my 70's home weatherproof.

great quality

I received product reimbursement in exchange for my honest review.  This silicone gasket can be used for sealing doors and windows to prevent draft.  The strip is 20 feet and can be trimmed to your desired size.  The product is self adhesive and the directions are easy to follow, so this is easy to install.

Easy to Install

This did the trick for an old seal on our garage door into the house.  It was easy to apply and is so far holding fast.  This is enough to complete one door with some left over. I'm happy that is is Made in the USA. I received product reimbursement in exchange for my honest opinion.

Very easy to install

I received product reimbursement in exchange for my honest review. The instructions are very easy to read and follow! I like that they included instructions for both doors and windows for me. The gasket looks and feels like it's made with quality silicone!

Quality!

Please Please do not order this item. I ordered it 3 times and 3 times I was given a refund .The package was opened and the item looked warped as if the heat had gotten to it from sitting on the shelf in the warehouse. The packaging that was send was not the original, there were no tears from where the package was opened.
