Our old threshold was in bad shape due to water infiltration. Looked around for a comparable replacement. Saw one online at Home Depot for over $100 but it was not in stock locally. Looked on Amazon and found what looks like the exact same item for less than half the price. Got it quickly but it only came with 4 nuts and bolts - we got the 73 inch version which should have come with 8 nuts and bolts, to match the 8 mounting holes. I contacted Amazon but they could not send additional hardware - only offered a refund or replacement (which I thought was overkill). So I contacted MD Products and they are shipping the extra hardware for free. I did a test installation with the 4 bolts and it looked good and fit nicely, once trimmed. As others have said, the wood part is held together with staples that don't hold that well, so I reinforced that with wood glue and a few finish nails (with pre-drilled holes, so as not to crack the wood) and this made it much sturdier. Also, check the photos in other reviews here on Amazon for great tips on how to secure the washers to the bolts. The included instructions for that were a little vague.

This product was well manufacture and arrived in good shape. It was half the price of what you would pay in big box stores. I would re-order this again.

What a poor product and presentation. The wood plate is in such a poor quality and brittle. It arrived chipped at the corner although the box was ok. I see that I'm not the only one who got it like that. It's because the wood quality is poor. And it did not come with hardware. It's ridiculous that we have to buy all the hardware. It's not just screws and nuts. You would need T fitting to make the adjustable height work. People don't have T fittings just laying around in the garage. In the product description, it says it will come with the hardware. Then upon receiving product, the slip says it does not come with the hardware. What a lazy seller. At least make things clear so people know what they are getting into.

As another reviewer suggested, this 73" threshold seems to be from "seconds" stock from M-D, hence the lower price than the 72" version available at box stores. The one I received had a very minor flaw in the wood on the underside, nothing that would affect installation or use. I would not buy this without 'free returns' available, in case the one received has unacceptable flaws. But mine also did not match the provided instructions for pushing the washer onto the bolt. Instructions show it sitting flush, so using a hammer with a socket to tap the washer into place would work. The item I received has the bolts sitting below the top surface by about 1/8" (as if a small wood plug could be place above to hide it?) Because of this difference, I completed the assembly by using a bench vice rather than a hammer. This allows a spacer (I used a hex nut) to be taped to one side of the vice, against which the bolt head can sit while the socket presses the washer on. See images. This made it very easy to turn the vice until the washer was snug. Aside from the above, installation follows the instructions. An angle grinder makes short work of trimming. (Tip: to remove your old threshold, slice it down the middle and take it out in two parts.) The aluminum and visible wood on my unit was flawless. I really like that it is adjustable since my old house has some issues with level floors, and also seasonal changes can affect the tightness of the door. I paired my installation with the M-D Building Products 69554 1-3/4-Inch by 36-Inch DB003 U-Shaped Door Bottom with Drip Cap. It's a quality component and mates well with the threshold.

Had to replace the threshold on our door that goes to the sun porch. I was kind of nervous about trying to replace that since it was built into the door, but it was really easy. It was long enough. I only had to cut one end and then I stained it worked great I’d buy it again, but I hope I don’t have to.

It can be functional, but it all three doors that I used these replacements I had to be creative to make them work. The quality of the craftmanship is mediocre, the wood is very low grade and will have defects that may or may not require a return of the product or coming up with a fix that will last. They are also very slim compared to most thresholds that doors originally come with.

Complete garbage and waste of time! Poor quality, arrived without packaging and missing all the installation hardware, I waited 2 weeks for the manufacturer to mail me the hardware, and then this junk broke when installing. The "adjustable" wood part arrived with a slight crack and turns out it was a severe defect because when I installed the leveling screws, the piece split! Two of the t nuts also pulled out of the base. This after I took care to stain and poly! What a complete waste of time! Stay away from this product!!! Wish I could get a refund for the hours I spent prepping and installing this!
