Can this be used for bedroom doors?
Asked by Nick July 3, 20202
AnswersThis is intended to be installed in a door frame with a kerf. I doubt an inside door frame will have a kerf. There are better alternatives for your application.
What can i use for a garage door that has a small gap
Asked by Smiley September 8, 20192
AnswersIf you are referring to an entry door from the garage you need to look at the existing seal to see if this is a match. If you are referring to the overhead door, this is not a match. It is way too small.
Will the foam take paint off of a painted steel door?
Asked by Brandon June 5, 20192
AnswersNo. It fits in a precut section of the door. The part that comes in contact with the door is very spongy.

Asked by pict May 11, 20192
AnswersProperly installed, it fills the gap it is sized for. If gaps show (A) it may be a flaw in the frame. (B) It isn't the product for your job.

After waiting around 4 or 5 weeks to get the product the overall quality was good. Inner foam core is dense and grey in color which keeps daylight from penetrating through. The only unfortunate thing was I ended up with one piece defective. The inner Kerf plastic liner that goes into the kerf joint wasn’t properly glued into the foam core. As a result, it deemed that piece useless.

Cheap door seal.
I guess you get what you pay for. I bought 3 of these to replace the old seals on my front door. I cut the pieces to size and installed them. Now it takes brute force to close my front door. And I cant dead bolt it without extreme effort. This is the EXACT same size seal as the one I replaced, only it is alot stifffer, keeping the door from shutting correctly.

Exactly what I needed; this fit my door perfectly!
The original stripping around my door was beige so I replaced all of it with this white Kerf which required 3 pieces (this is NOT a kit as others have mentioned in the Q&A; this is a single 96 inch piece). I had the job completed, including removing the old Kerf seals and cutting the new ones to length, in just over 10 minutes. The white color matches the white door frame and is a much nicer look, in my opinion, than a different color Kerf.
REMOVAL
You may need to use a flat blade screwdriver to remove the old seal but only to get it started. Once you have one edge separated from the door, you can just gently pull and it comes away from the door like peeling away tape after painting.
PREPARATION
Once you have all the old removed, take a close look at how the top and side Kerf/slots overlap or how they do not. It's important to understand how each corner at the top of the door overlaps to insure you cut the pieces the correct length. For example, I needed a full "door length" piece on one side, 95% "door width" at the top and 95% "door length" on the other side for the top corners to meet properly and create a complete seal to the door.
INSTALLATION
To install the new Kerf, just press the PVC piece into the slot on one end and slowly work your way to the other end. You don't need any tools, you can just press it in by hand. I found standing outside the door with my thumb on the outside of the frame, wrapping my fingers around the Kerf and closing my hand was the easiest way to install it. Be sure to lay your piece in properly so the "top point" of the Kerf (where the two foam edges meet) always faces towards the center of the door opening.
Now the next time the dog decides to tear it up, I'll know what to do.
