Strong and effective weatherstrip
Cut to length to fit your door. You may need to trim off a small tab at each end so the plastic doesn't hit the door jambs if they are a tight fit with the door. Once tapped into place, the sweep stops drafts and seems highly durable.

Excellent product for a windy hallway
This definitely a two-person project. My Wife Christina tremendously helpful since we had to hold the door open and whack the length of 34 inches with a hammer against a 2/4 to get it in place. Then saw off the excess. But does the job!!!

Well made, designed for snug fit trim/saw to size
Trim to size of door with a hand saw of some Type (I used a hacksaw.) then slide it on to bottom of open door. Note; the more it slides on the more resistance to moving it became. (To hold it securely in place when on completely.) To push it on: I used a hammer turned sideways to tap-apply even pressure on the side to avoid any possible impact damage to finish sliding it in place. I would buy it again.
