M-D Building Products Vinyl Cinch® U-Shape Door Bottom Seal, Slide-On Weatherstripping Draft Stopper, Easy to Install, Fits 36” x 1-3/4” Doors, Fills 3/8”- 3/4” Gaps, 43336, White

I'm surprised at how strong the material is! I recommend using a saw, I used an inexpensive ($10-15 at Lowe's or HD) miter saw, or at least use a hack saw. This is not soft or weak plastic that you can cut with a utility knife. This product is functional and easy to install.

These replacement door sweeps were much easier to install than I expected 👍 🔧 Installation • Pulled the old sweeps off and used them as a length guide • New ones slid right on with no fuss • Took just a few minutes per door ✂️ Cutting options (worked great for French doors) • We cut one with a hacksaw, as recommended • For the second sweep, we used tin snips instead and it worked perfectly • Tin snips were especially helpful because this was a French door where the trim between the doors doesn’t touch the ground • The outside piece fit neatly over the trim, while the inside covered the gap 🚪 Fit & function • Covered gaps well • Sealed nicely at the bottom • Everything lined up cleanly once installed Overall, these are very easy to use, forgiving if your door setup isn’t perfectly standard, and worked well with both a hacksaw and tin snips. If you’re replacing worn door sweeps, this is a straightforward, DIY-friendly option.

This gasket is the best you can buy out there (IMHO). I find it is best used if the gap is ½” to ¾”. Less will possibly work, but you may quickly shave off the dangling legs. These can be somewhat hard to install on a 1 ¾” door as the fit is super tight (compression fit). That is why there are no holes for screws. Here is the installation that worked for me (second one installed and lessons learned). 1) The Mark: (if required. Yes, I know it is 36” and so is your door, but trust me). Lay at base of door, flush at one end and mark opposite end at end of door. Trim as below - if length is perfect, skip to 3). 2) The Trim: (lesson learned from installing as is - ¼” extended past the door edge hitting the side frame. Not fun to remove). Use anything you are skilled with: Hack saw, band saw, chain saw or whatever. Here is what I used/did. I used the heavy duty scissors to snip both upstanding legs (as far as I could). I then snipped each dangling leg at the same distance as the upstanding legs. I then used a sharp blade against a small section of 2x4 to cut the bottom – was tough and takes patience / great force. (see cut piece in pics – yes, my door is 36” and I still trimmed off about a ¼”. 3) The Install: Spray Windex on both sides of the lower sides of the door along with a shot that length of the seal (insides). Yes, Windex – as any avid dirt biker knows – lubricates for install and evaporates for a extremely tight seal (like grips on your dirt bike!) Should have bought this stock in the 70’s. 4) The Slide: Before the Windex evaporates, slide the seal from outer end of door (as if you could install any other way). It will be easy for the first 6”, then you will need a gloved (leather preferably) hand to pound it on most of the way. I got it to about to 3-4” left before my palm gave out. From there I used a block of wood (to protect the seal) and a small hammer (yea, the one shown is a tiny tike hammer, but the one I use the most) to tap the seal flush to the door. Now you are almost done. 5) The Pop: More than likely, the seal is up to the bottom of the door. I couldn’t even move my door as it was sealed to the floor. I used a rigid scraper (metal as shown – I have rigid and flexible and had to use the rigid one) sliding under the seal (gently not to damage the dangling fingers) in 6” increments and pulling up (you will hear the pop as it seats with the bottom of your door. I did this to both inside and outside of door. Key: From the Windex spray to the end was done before the Windex dried. Hopefully this helped with the installation.

Not as easy to install as advertised. My door is 1 3/4” so it should just slide on, but it wouldn’t, I had to use a mallet and WD40 to get it to slide on. The outside snapped into place, but the inside would not, leaving a small gap. It could be that after 20 years, the very bottom of the door may have swollen a bit. It works though.

I used Tin Snips to cut off the excess as my door is measured 35.5". It cuts well and I had to use rubber mallet to pound the cinch fit onto the door base. My door threshold has almost the same height as the floor and thus the fins rubs on the floor. Regardless, while the switching from opening to closing has a bit of resistance, once the fins faced the other side, the door glides close smoothly. This solution works better than my previous solution of one layer of adhesive sweep on the outside. The adhesive doesn't stay too long. But this particular solution is very secure and I have the confidence that it won't detach for any reason. My only concern is taking it off if the sweep degraded because of the friction with the floor. But hopefully it won't need to be done. Regardless, the fins seal pretty well and I'm happy with the purchase. Update: The inside fins are very flimsy. Our floor scrape the bottom of the sweeps as the door is very low to the ground. The fins outside are fine but the fins inside get dragged and pinned to the outside fins and ripped them out and left an ugly trail that I need to cut off or it will keep peeling off.

Fit front door perfect, doesn’t move and has air tight seal. Great quality weatherstripping. Also easy install and to trim length with light sanding of edge to give finished edge.

This U-shaped door bottom weatherstripping seal product is made well. It is made in the USA with globally sourced materials. It is a bit difficult to slip on the door bottom when the door is attached to its hinges, but it can be done by starting with the top of the U-shape and don't push it upwards to the door bottom until you slip it inward as far as you can by hand, then using a mallet the remainder of the product can be set flush to the door edge. The instructions state to use a hacksaw to measure and cutoff any excess product but this is not a good instruction because a hacksaw can result in the end of the product not being cut square to the door edge and then leave a gap at the edge of the door. PRODUCT SUGGESTION TO THE MANUFACTURER: SINCE A STANDARD DOOR WIDTH FROM EDGE TO EDGE CAN TYPICALLY RANGE FROM 36 IN., TO 35 7/8 IN. (35.875), TO 35 3/4 IN. (35.75), IT WOULD BE MUCH BETTER IF THE PRODUCT WAS FACTORY PRE-CUT TO FIT THESE THREE (3) POPULAR DOOR WIDTH SIZES. THEN THE BUYER CAN MEASURE THE DOOR WIDTH AND ORDER THE BEST SIZE TO FIT THE DOOR. BECAUSE OF THE PROBLEMS ASSOCIATED WITH USING A HACKSAW TO HAND CUT A UNIFORM SQUARE CUT IN THE PRODUCT TO PROPERLY FIT THE PRODUCT FLUSH TO THE DOOR EDGE, I WOULD NOT RECOMMEND THIS PRODUCT TO THOSE WHO DON'T HAVE THE SKILL TO MAKE A STRAIGHT CLEAN CUT.

Extremely easy installation! I had a very old Larson storm door which needed 3 seal fins. The MD Clinch seal was cheaper than just one of the seal fins!!! The door was only 1 5/8" thick rather than 1 3/4", so I added a strip of aluminum to act as a shim ... worked great!

Item as described and keeps draft out

So easy - slides on to bottom of door (Use a hammer to tap it along, into place). It was a little too long - Instructions recommend trimming with saw, but I managed to use a kitchen knife to make a groove, and then I twisted off the extra plastic with a wrench. Just be innovative! Now door closes perfectly and no gap under the door. Once I took off my old door stop piece to replace with this new one, I saw why there was a gap - the old one had all the vinyl flaps worn off. Seems we need to replace every 3 years or so. Worth it for 20$ and so easy! This one has lots of vinyl flaps to keep the cold out.

Excellent product! Easy to cut to the length size-was able to do the both double doors and just looks incredible. I may have to order more. Thank you!

Altamente recomendado. La pieza llega de un tamaño estándar a lo largo en el que se puede ajustar al tamaño de la puerta donde se desea colocar. Es fácil de cortar a la medida deseada y, una vez colocada en la puerta hace un cierre hermético que no permite el paso del polvo. La instalación en la puerta es superior sencillo.

Es muy bueno no entra ni el agua ni los bichos. Desafortunadamente con el uso se le están cayendo las bandas internas. Mira la foto.
