Trademark Soundproofing TMS Automatic Door Bottom/Heavy Duty High Sound Control/Fully Mortised / 36" Long

Pretty straight forward but a couple of installation notes.First, instructions say to cut the door bottom the same length as the door. It should be cut 1/16" short to allow an easy mortise of the door bottom side covers. If your door is tight before you begin. the covers will scrape against the jamb without them being mortised with a hand chisel.Secondly, the mortise cut for the door bottom should use a 15/16" straight router bit to a depth of 1-1/4" and a 5/8" straight router bit should be used for an additional 7/16" depth to accommodate the narrower top part of the automatic door bottom. The covers need wood to screw into and a full 15/16" mortise removes the wood where the screws would be screwed into. I found this out on the first install and had to use epoxy to fill the void so I could attach the cover plates.I used a full sized Bosch router and two Bosch edge guides that were snug and centered on the middle if the door bottom. I routed vertically because the edge guides aren't very deep and didn't want the router to tip, if done horizontally, and mess up my door. The setup takes much longer than the router cuts, so take your time and double check that everything is secure and centered.Once setup, you can bang a bunch of these out in a relatively short time with doors that are all the same thickness.I installed one on our bedroom door and another on our home theater door. Huge sound difference since I took the time to insulate staggered stud wall cavities prior to drywall.

We installed some new flooring and in the process of leveling the floor - we had to take off the door sweep so that is would open properly, but that left a BIG air gap at the bottom of the door. I first heard about these door mechanisms from "Ask this Old House" (ASK This Old House | Drafty Door, Clean Paintbrushes (S16 E25) FULL EPISODE - About 8:20 into the clip). The big challenge for me was cutting the mortus required for a hidden installation. I took the door to our local "The Door Store" and they did a great job. Brought the door home and installed all the hardware. IT WORKS GREAT. Nice not having the ants march one by one (under the door) to get out of the rain.

Not a difficult install, just take the time to slowly do it correctly.The great benefit of this door sweep is that it lifts upon opening and does not rub or wear to make black marks on the carpet or vinyl flooring.When the bar does lower to seal at the threshold, it makes a great wind & light seal when adjusted correctly (and keeps the bugs out).

This seemed to be a well-made, well designed product. I was going to install it in my front door, but found extensive insect damage necessitating replacement of the entire door and frame assembly. So, I won't be able to use need it and returned it to Amazon.

works well
