MD Building Adjustable Aluminum & Hardwood Threshold, Bronze, 36in

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.

If you want it longer then 4 and 5/8 of an inch there is an add-on you can buy which tapered the nose down should have came with it I think but it's good quality

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.

A good resolution to my problem.

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.

36" exterior door over concrete with 2×4 wall PERFECT product

When I got the product it was missing 4 of the screws to adjust the riser. I contacted the manufacturer through Amazon and they made it right. Took a week to get the missing screws.

French door threshold was my use and it worked very well. Things to note: as the instructions (hopefully your comes with them) stated that the supplied washer looking lock rings need to be tight against the underside of the floating plate. I used the barrel of a universal screwdriver to bang it tight. Once in place they are very difficult to remove. I needed to convert a single door threshold to non-adjustable and had to cut the washers off. These washers create the adjustment feature. Why "3rd time a charm" It took 3 shipments to Hawaii for them to get me the item I ordered. I gave up on Prime free shipping and paid for for it and magically the right item arrived. Oh well, at $75 with shipping it was a steal.

Not a lot I can say, but these are nice. Had this shipped to Australia, as what you can get in Australia at big box stores are low quality plain. This one is adjustable and seen these in the USA, and they are nice with the adjustable feature. Installed on our external door, and looks fantastic! Far better than what I can find here.

This door threshold exceeded my expectations. It was easy to fit, and was made from quality materials, we are very pleased with the purchase.

It was perfect for a double door we installed in our cabin. Fits perfectly in a 2x4 wall construction and was easy to cut to size.

Disappointing! For what you pay it looks like a chipmunk chewed the anchoring holes. If you’re looking for a quality finish I would not recommend this product. Thought I was getting a quality, finished product.

I am so happy with this purchase. It is impossible to find door sills these days. Door and window companies stopped supplying framing materials for old doors. I wanted to re-purpose older doors that suited my needs without having to buy new doors and toss them out. You have to purchase the door to just get a new frame. This was the best thing ever! Thank goodness.
