Quick Summary
The M-D Building Products 68247 is a heavy-duty aluminum door sweep with a thick rubber seal designed to close gaps up to 3/8 inch between your door bottom and the threshold. It screws directly into the door face, comes with hardware included, and works on both interior and exterior doors. It’s UL-94HB rated for fire safety, and the aluminum body means it won’t flex, warp, or degrade the way adhesive foam strips do after a few months.
What’s in the Package
You get the 36-inch aluminum sweep with the rubber fin already attached, plus the mounting screws. That’s it — no adhesive strips, no complicated parts. The whole thing is ready to install out of the box. If your door is wider than 36 inches, M-D makes a 48-inch version as well.
How the Install Went
This is a screw-on door sweep, not a peel-and-stick. You hold the sweep against the inside face of your door, line it up so the rubber fin makes contact with the threshold, mark your screw holes, and drive them in. The whole process took about 10 minutes with a drill. No special tools, no measuring tape drama. The screws bite into the door cleanly, and once it’s in place, the sweep feels rock solid — it’s not going anywhere.
One thing to watch: make sure the rubber fin touches the threshold without bunching. If you mount it too low, the door will drag. Too high and you’ll still have a gap. Take the extra minute to get the height right before you drill.
Does It Actually Block Drafts?
Yes. The difference was immediate. Before the sweep, I could feel air moving under the door — especially noticeable with the AC running. After the install, that gap was sealed. The thick rubber fin compresses against the threshold and creates a tight barrier. Dust intrusion dropped noticeably, and the draft was gone.
The rubber is firm enough to maintain contact but flexible enough that the door still opens and closes smoothly. No scraping, no sticking. It just works.

Build Quality
The aluminum carrier is legit heavy-duty. This isn’t a flimsy piece of trim — it has real weight and rigidity. The rubber seal is thick, rated UL-94HB for slow burn, and feels like it’ll hold up for years. M-D Building Products has been making weatherstripping and door hardware for decades, and the quality here reflects that. You can check out their full door sweep lineup on the M-D website.
Compared to adhesive foam strips or stick-on sweeps, this is a different tier. Those cheaper options tend to curl, lose their seal, or fall off entirely within a season. The screw-on aluminum design eliminates all of that.
Pros and Cons
Pros:

- Thick rubber seal blocks drafts, dust, and light
- Simple screw-on install — 10 minutes with a drill

Who Is This For?
Homeowners dealing with drafts, dust, bugs, or energy loss under their doors. This is a permanent fix — not a temporary band-aid. If you own your home and want something that installs once and stays put, the M-D 68247 is the right call. Renters who can’t drill into their door might want to look at adhesive or slide-on alternatives instead.
