Suptikes 4 Pack Door Sweep, Door Draft Stopper with Strong Adhesive, 1.8" W x 37" L, White

What size gap does this work for?

Does the tape goes in the inside part of the door or out side ?

Could I attach to bottom of warming/storage drawer on stove to keep cat toys from rolling under the stove?

how come 4 pack product has lower ratings than 2 pack product?
