   If there's a threshold under the door opening, I would use the neoprene door bottom. If it's barely clearing the concrete floor, I would use the brush type for its greater flexibility. Keep in mind that the brush type is inferior to the neoprene as far as weatherproofing and critterproofing.

   The brush doesn't seal as well in ideal circumstances, but will tolerate more irregularity and misalignment -- will seal reasonably well where the neoprene seal would either show a gap or wear/tear out rapidly.

   Thanks for the replies.

   The door is actually two of them -- both 4' wide doors that are an entrance to a garage with a concrete floor. There is no threshold, just the floor, which is smooth concrete, save for a crack or two. There is a crown in the floor, so the gap to close is about a 1/2 an inch at the center where the doors meet and between 3/4" and 1 1/4" at either end where the jambs are. Where it swings out the driveway slopes down.

   I'm leaning toward neoprene, primarily for the ability to keep out the rain.

   How much longer should the neoprene be than the gap it is closing?

   Thanks again.
