M-D Building Products 80630 36 in. Bronze Aluminum U-Shape Commercial Screw-on Under Door Seal

I am very happy with my purchase, this thing blocks all the water from coming under my door during a rain storm even with driving wind, This got tested during Hurricane Grace.Pluses:Well built out of good metal and a very impressive wide rubber water stop on the bottom that can slide out and be cleaned or replaced.Installation is easy but remember to coat the inner side of the metal strip that face outside with a bead of silicone or caulk. Water will hit the front of the door and drain down under the front metal lip and rot out your doors bottom if you don't use some kind of sealant.Cutting it to size was easy and can be done with a hacksaw or Dremel.Negatives:Paint coating on the metal can chip easier than I expected. I ended up with two 1/8" chip marks on the outside. I touched them up with black paint.Mine did not come with screws but that was an easy fix as I had some in my tool box.Don't see replacement rubber strips online, I would feel better knowing I could buy them.Summary:Overall very happy with the purchase. It looks good and does it's job very well.

Works great

This door weather seal is a very well-made item. The product is anodized aluminum 36" in length and MUST be trimmed to fit, if you have other than an exact 36" door, of which there are MANY. If you do not possess the tools, nor the skills required, then you should probably opt for one of the cheap plastic substitutes - this item is designed and manufactured to last a lifetime but it requires SOME handyman skills to install correctly. For example, those complaining about the rubber strips tearing on the unit, obviously, do not understand the need for a PROPER clearance between the bottom of the seal and the door sill/threshold; this is most easily accommodated by an adjustable threshold. If you have too great a clearance = NO adequate seal. If you have too little clearance = abraded rubber strips, often in short order. Proper tools consist of something adequate to cut aluminum: hack saw, Dremel tool, chop saw, etc. and scissors to trim the rubber strip. Some other complaints consist of missing items, e.g. rubber seal, screws, etc. These MAY have been missing from the manufacturer's packaging but my guess is it's more likely a result of a "return" which was "recycled" to another customer, who can be sure? Another couple of complaints refer to an improper fit but, as one reviewer offered, if your wooden door has already taken on water for a protracted period and, thus, has swollen, you won't get this precisely manufactured item to fit - by then it's too late. Some have commented on the product supplied being darker than the picture; this is true, so beware if you want the color in the picture. I find the actual tone to be fairly accurate to what I see advertised as oil-rubbed dark bronze. OK, so now having lauded the qualities of the product and, hopefully, corrected a few misconceptions, here is what I find inadequate in the design of this product: there is NO thermal break to deter FRIGID outside temperatures, experienced in the winter Northeast, from migrating to the inner 3/4" strip of the U-shaped component. On VERY cold days, I have experienced condensation on this interior aluminum strip as the warm interior house heat contacts this cold strip - not very desirable, especially when it is situated above a hardwood floor. The manufacturer should have allowed for this and provided a thermal break in the design. I have installed this setup on an interior-swing atrium door above a M-D exterior threshold, which does incorporate a thermal break for this reason. M-D should have split this component longitudinally into two overlapping aluminum pieces with an insulator between, or, change the design to a L shape rather than a U shape to prevent cold transmission to the interior "U" strip. Otherwise, GREAT product but I have to knock it 1 star and give it a 4 for this reason.

I’ve installed 3 of these, figured I’d give step-by-step instructions.* cut your door 1/2 inch from the threshold. Your can slide the door bottom an additional 1/2 inch down, so err on the side of larger gaps. I cut mine to 5/8th to account for the threshold not being perfectly level.* cut the door bottom to the width of the door. I used a mortise gauge to mark the line and a hacksaw.* use a sanding block (220 worked for me) to clean the cut edges. Also, sand the inside where the holes are drilled as they may have burrs which will mar your door* test fit the door bottom and mark where the weather proofing on the sides touch the door bottom.* use the hacksaw again to remove the drip cover (curved bit on the front) so it doesn’t interfere with your weatherstripping. A Dremel also works and is better, but takes longer.* slide in the rubber bottom and cut it to fit* close the door and push down the door bottom until the river barely touches the threshold, you shouldn’t see any light* screw it to the door* use something to paint the cut metal, I used a sharpie, but I don’t now if it’ll hold.All in all a good product and pretty easy to install. I wish they sold pre-cut versions.

Strong, reasonable price, good quality. Fits well with one caution, it is 36" exactly, too wide for a typical 3-0 door.
