M-D Building Products 47000 36 in. Brown Vinyl Concealed Screw/Nail-on Under Door Seal

Measure your gap. I have an adjustable threshold and all the way up I still had a gap with my old worn seal. This one was way thicker for up to a 3/8" gap. I then had to adjust my landing all the way down and it is just a little snug but good. My old one was glued on and I chose to screw this one on and it has a sturdy back for a firm mount. No mounting hardware included.

Perfect

It was slightly bigger than the door but not hard to just razor off excess. Would have given five stars if it also come with the nails required. Does not have sticky back, we used glue and then nailed in.

This was a good fit for my door. You have to use nails or staples and /or adhesive to secure it to bottom of door. Worked well for me.

Great product … worked great and fit perfectly under our back porch door

Product as expected. Deep enough that I had to adjust door sash to allow door to close easily. Seems to be of good quality.

The bottom seal on my front door was gone and I had not realized how much insulation we had lost due to this bad seal. I replaced the bad seal with this new one and we noted right away the house being cooler as the temperatures are already hitting all time high for Houston closer to the end of May. To install it, I had to remove the door so as to have good access to the bottom of the door. After removing the old seal and cleaning well the surface, I covered the surface of the seal that contacts the door with clear silicone caulking and finally re-using the same nails that were attaching the old seal I nailed about 10 nails spaced apart approx. 3 inches. There were no issues closing or opening the door after the installation and today, several weeks after the seal was installed, it is performing well. I recommend it.

Fills the gap. It's just flat on the bottom. No channels. Feels like thin rubber/plasti over thin metal. I had to tape it to the bottom of the door to nail it on. Better than a plastic one I guess.
