M-D Building Products 78600 5-5/8 in. x 1-1/8 in. x 36 in. Silver Adjustable Aluminum & Hardwood Threshold Kit – Versatile Solution for French and Exterior Doors

Great threshold, much less expensive than the big box stores
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.

Disappointing Experience All Around
Delivery Issues:I had to wait an unreasonable 4 weeks for this product to be delivered. The extended delay was frustrating and inconvenient.Poor Quality:When the threshold kit finally arrived, I was extremely disappointed to find a large knot in the wood with a significant chunk missing from it (see attached image). This defect is not just an aesthetic issue but also compromises the structural integrity of the threshold.Durability Concerns:Given the poor condition of the wood, I have serious doubts about the durability and longevity of this product. For something that is supposed to withstand frequent use on an exterior door, the quality is simply unacceptable.Overall:I cannot recommend the M-D Building Products 78618 threshold kit. The long wait and poor quality control make this product a bad choice. Save your time and money, and look for a better alternative.

Looks and works great.
Would have given 5 stars but screw package was not secured inside box and ended up making marks on the metal surface of threshold. Could have easily been prevented. Otherwise it looks and works great. I did have to trim a little bit off the metal corners to fit around existing door jam.

Difficult assembly. Moderate quality issues.
I bought three of these thresholds to replace the factory thresholds on some Jeld-Wen doors that had to be reinstalled (removing the doors damaged the originals). I found the following:Pros:++I got them to work.+My carbide-tipped miter saw had no problem trimming these to a true 36″, my required dimension. Out of the box, they were ~1/8 inch larger than this.+Aluminum components seemed sturdy, and were well bonded to wood base.Cons:—[THIS IS THE TLDR PORTION!!!] The “washers” used to keep the adjustable threshold up have to be press fit onto the provided bolts, or the threshold will just fall back down. I did this with a hammer and a bit of tube. In the disassembled provided state, the washers won’t move above the threaded portion of the bolt as described in the instructions without mechanical force. These really should have come preassembled to the adjustable oak component.—Very poor instructions (see above). If you follow the instructions to the letter without extrapolation, the threshold will not work (will just go to the lowest position and not stay up). I had to disassemble the factory threshold for guidance on how to make it work.-The various sub components were not completely aligned (trim stuck out further than aluminum, which stuck out further than the wood base, etc.).-Front trim piece is very lightly stapled on, and will come off and need reattachment.-M-D also makes a 2″ extension piece to make these work with a 2×6 wall. The extensions work…sort of. They tend to “pop” back up after installation, as the bottom aluminum retention lip is miniscule.Meh:-Oak pieces chip easily. This is kind of expected though for a wood piece, so not really a con. It may be a reason to consider a vinyl or composite-style threshold instead.

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.

Benchmark for other suppliers. Fast-fits-Fabulous. Thanks.

Missing hardware, warped trim stapled on. When I contacted the manufacturer they told me to contact Amazon adding more time to correct a problem created by the manufacturer. This is not help. I value my timeI replaced the very poor quality wood products with my own wood as I felt the large knots at each were not stable enough and may over time become loose. Not everyone can do this nor should they have to.The aluminum sill is top notch but everything else lowers my rating.
