FebosDoor Noise Blocker - 36 inches Grey Door Draft Stopper- Door Silencer Sound Proof Door Draft Guard

My son's dorm room door is 1.7" thick. Will this work ok with a carpeted floor or will it get jammed nd not allow the door to open???

How do you adjust the inserts that the foam is supposed to go in? I understand you can cut the foam part, but will the inserts fit my 2 foot door?

Where was this made?
