Pictures: before & afterSimple installation. Dimensions were perfect, no need for alteration. Sealed the door gap entirely. Great product.

Door sweep fit perfectly to my door. Easy install, with the four screws on the inside of the door, I also drilled into the bottom of the sweep/door four additional screws for extra securement. Cosmetically looks great, and functionality outstanding! Well made product right here!

Used to replace seal on a 42" outside door. Fit well and easy to install, added screws to the outside to hold rubber seal against the threshold, works much better than the original.

Great product but did not come with instructions. Easy enough to figure out but screw cover (inside) is difficult to slide on. I used soapy water and with a little effort was able to complete the project. My exterior door was 1-3/4” thick and the threshold seal fit perfectly.

I've had this installed for about 4 months now. Summary: It was an extremely good purchase. Enough for me to write this review.This was for a garage side door that had about a 3/4" gap between the sill and the bottom of the door. The garage is heated and it is where we sleep our dogs. I had tried other door skirts and was getting resigned to needing a Door Sock, which you have to move and place each time your open the door. But then I tried this one.What a difference. The temperature in the garage jumped to within 1 degree of the main house, even in sub-freezing weather. Older, less effective sweeps would let the garage fall 6-8 degrees below the house; you could feel the cold getting in, and it was from that door gap.Installation was straightforward. The height is easily adjustable and covers a very wide range, easily closing my gap problem. The multiple bottom seals are very effective and were set to be just-the-right-snug, offering extra protection against pests, which was a bonus.But the big win was stopping the cold air drafts. This item was worth the extra cost. It's hard to quantify in engineering terms, but I''ll bet this sweep is 10x more effective at stopping drafts than cheaper single sweep solutions due to the better fit and seals. At least for me.And my dogs stay warm. Yay!

… but, I wish they wouldn’t have cut the outside so short. This is for our inside door leading to garage. Was not able to use the rain guard part to cover up how short they cut the other side. Had to drill new holes since it doesn’t line up with the original holes. It makes the door hard to close even pushed all the way up. The contractors who built our home put the door in super crooked since they also didn’t put the drywall in straight the door frame is not square. We added new hinges and new insulation plus this. Outside of machining issues and being cut too short on one side, it still looks better than what the contractors who built it gave us. Hoping over time the rubber compresses a bit so we can close the door normally again. It seems to help with drafts but is really a tight fit and makes the door hard to close.

Probably the fastest and easiest home improvement project I've ever done. (Okay, maybe replacing an outlet wall plate is easier but this was close.) The whole thing was done in close to 15 minutes, including rehanging the door and putting away my sawhorses and tools.Here's what you do:1) Be sure you're buying the right size for your door.2) Pop the hinge pins, and lay the door on a surface you can work on.3) Remove the old sweep. This may take some doing, depending on yours, but mine pried right off.4) Slide the screw cover panel of the new sweep off its track. (No need to pop it off or back on, which might be where some people have reported this being difficult. It's not. Just pull lengthwise and sliiiiide it away.)5) Dry fit the new sweep, screw holes facing INSIDE the house!6) Rehang the door. The sweep should stay in place as you do. If not, try a little painters tape to hold it in place?7) Adjust the sweep to the level you need for a true fit, then set the screws. I recommend starting with the two end screws. This allows you to micro-fit the middle to perfection. The screws self-tap, but if you have a metal door like mine, you may need to lean into it at first.8) Slide the decorative screw cover panel back on from the edge of the door. Again, don't try to "clamp" it in place. Sliiiide it in like butter.9) You're done. Put away your tools and enjoy the rest of your day.The only downside to this whole process is that I was done so fast that my neighbors probably didn't even have a chance to be impressed with my door-hanging skills. Still, thanks KS Hardware for designing something that's a breeze to install but will keep the breeze out!

I viewed the mixed reviews for this product and looked at the alternatives at Lowes, Home Depot and local hardware stores and decided to spend the extra bucks for this sweep. I decided it was easier to remove the three hinge pins and the door for installation rather than mess with trying to slide it on with the door hung. I slide the sweep onto the door with it sitting on edge on the floor then reinstalled the door. The sweep was at the perfect height so I drilled the holes and installed the mounting screws, being careful not to overtighten so as to not warp the plastic. Next, I slid on the screw cover trim without a problem, gently tapping it the last few inches with a hammer until flush with the end edge of the sweep. Very happy with the end result as it closed the gaps that were present with the old sweep and the door still closes easily. Total time for installation was less than 15 minutes, start to finish. I would definately buy this product again.

Best door sweep available - period. I gave up replacing cheap ones every year - these work better and are of a quality that will help avoid regular replacement. Excellent.
