      Q:I have a 32 inch wide, 1.75 thick exterior door with only a 3/16ths inch gap to the bottom door jam. Is there a product that can fit that small gap? Original seal was simple vinyl piece as far as I can tell without removing the door.

      A:  Hello SamD, We only make our Under Door Seals fit gaps from 3/8" to 3/4" just depending on which item you are to get. I'm sorry we do not have anything for that small of a gap. I would recommend looking at a door sweep as this will help seal that gap. Thanks!

          A:  It is going to depend upon what the clearance is between the bottom of the door and the threshold height. I would suggest that you slip the seal on the door while it is open, then measure from the floor to the bottom of the seal. That will give you an idea of how much clearance you have available for a threshold.

          by|Dec 15, 2020

          A:  Looks like you are on the right track here. Remove the old door threshold and replace it with this door seal.

            Looking forward to keeping the creepy crawlies out of my garage office. I received this item in exchange for a review. The door seal came with good instructions for cutting down the seal if it is wider than your door. Once I had trimmed it down with a hacksaw it fit just fine. The seal uses diatomaceous earth in the fins at the bottom to get rid of any bugs that rub up against the fins. Do be careful when trimming the fins. In retrospect I think I would have been better off trimming them with a box knife rather than continuing with the hacksaw. The seal fits fairly tightly against the door but if it is a bit loose I would use a bit of double sided gorilla tape or some small brads to secure the seal.

            Well, I just bought it a few days ago and my son just installed it so it’s kind of early for a review. But I can tell you that it looks like better quality than what was on there when I bought the house.
