Our I-Beam Mounts are stationary mounting systems for punching bags up to 300lbs. They are the sturdiest in the industry and built to last a lifetime. Simply slide the mount onto the I-Beam and tighten the bolts and nuts. Installation takes less than 5 minutes! No drilling and no mess. In addition, each mount is made up of 3/16” steel and finished with premium black textured powder coating.
