Rated 5 out of 5 by 10 reviewers.
Rated 5 out of 5 by Door seal Have a puppy that loves to scratch at the door have had to replace many times,this seal works great I can tell the difference when it is leaking and not, installs very easy and works great. August 29, 2014
Rated 5 out of 5 by Easy to install, great value. My cat loves to destroy door kerf, so I keep some as back up too. Very easy to remove and replace. May 13, 2014
Rated 5 out of 5 by Great but why only replacement kerf? This seal material stays supple and continues sealing well even in the coldest weather. I'm puzzled, though, why I can no longer buy it at Home Depot with the slotted wood trim piece so I can do custom sealing of doors and windows. January 30, 2014
Rated 5 out of 5 by best product I can find! This door seal is the best I can find. Creates a wide seal area, capable of sealing large differences in deflection, by which I mean it fits the contours of a warped door easily. As a general contractor, I highly recommend this product. Far better than any of the peel and stick garbage. June 25, 2013
Rated 5 out of 5 by worked on my Peachtree door with 1/4" kerf I have an older door with the larger 1/4" kerf. I fit .175" diameter screen spline along the entire length of the new weatherstripping. I worked both into the kerf at the same time with a 3" flexible putty knife. This gave me a tight fit, better than the original Peachtree weatherstripping. The old weatherstripping had sagged and was damaged. No more drafts and I can still remove them for painting if needed. November 25, 2013
