Review: Awesome piece of hardware for professional installation - Wow this was a pain in the butt to install, but it works and looks amazing! I live in a condo and can't change the look of the outside of my front door, so this was the only feasible alternative to those cheap sliding foam door sweeps. The construction feels very solid and the mechanism is smooth - no one knows it's there unless I point it out. Just keep in mind you need a solid door and professional tools. A local woodworking shop crafted a jig and routed it; a metal chop saw worked well to trim it a small amount to fit in a 35-7/8" with end plates. Another thing to keep in mind is that it can clearly handle angles/slants in the frame no problem, but can't seal gaps caused by waves, divots, or similar, curved imperfections. The drop adjustment was easy, but no way of knowing if it will stay put over time. If anything changes, I'll update this review.
Review: Missing gasket: product ineffective - Despite arriving sealed and new-in-packaging, the product is missing a very important piece: the gasket (see pictures). The product listing shows the gasket, as seen highlighted in red in first attached photo. However, upon receiving the sealed, unopened product, it did not contain this part. As such, its ability to create an air seal between faces of the door is entirely compromised, as well as any “soundproofing” capabilities. In reviews for other similar products (different lengths) by same manufacturer I am now seeing similar complaints about the same part missing. It’s upsetting to see that after several years, these products are still being sold without the shown parts from the listing. Update: I contacted the manufacturer, to which they seemed very surprised (though I'm unsure how, as this issue has been reported in the reviews of these products since at least 2019). They told me order replacement through desertcart. I received the replacement, which like its predecessor, is also missing the same gasket/seal. I will contact the company again and will update this review if the issue is addressed. Until then, it's a safe assumption the entire batch is missing this critical part.

## Questions & Answers

**Q: Are both the internal and bottom seals included?**
A: All the seals are included.

**Q: When routing the door 0.924" wide is specified in this Q&A.  0.924" is not a standard router bit. How is this done?**
A: Use a smaller bit and take 2 passes

**Q: A commercial doorway is 36" with the door being just under that. Will this need to be trimmed to fit??**
A: Depends by how much less than 36" the door is. There is a possibility you may have to trim a bit or it may fit if there is some space between door and frame.

**Q: When routing the door 0.924" wide is specified in this Q&A.  0.924" is not a standard router bit. How is this done?**
A: I'm going to say that 1" is probably fine, as long as you have at least a 1-3/4' door
