Anyone have experience with hanging a heavy bag from an I-beam? I am considering putting up a heavy bag (100 lb) in my basement using an I-beam attachment, but I'm worried using the bag will shake/loosen up the floorboards upstairs.
Here are some pictures of the beam:
It is a 3 1/4" flange and the bottom of the beam is 7'4" off the floor. Any advice is appreciated. Thanks.
