  "description_excerpt": "Aspects of this disclosure relate relates in general to weightlifting equipment, and more particularly, to weightlifting equipment that can be utilized with racks and rigs in the form of a bracket assembly configured to be coupled to a rack or rig.\n\nThe use of weightlifting racks and rigs is ever increasing. With the recent surge of popularity in “lifting heavy things” and the traditional weightlifting exercises, many more people are utilizing racks and rigs. In fact, there are many home gyms that are now centered around a rack or rig.\n\nTo support the weight of a barbell or the like, brackets or the like can be coupled to the beams of a rack or rig to support the weight. In certain embodiments, the brackets may be grasping hooks. These brackets, hooks or the like can be positioned at a number of different locations on the beams so as to adjust to different size individuals as well as to different lifting exercises. One such hook is known as a J-cup. Such a hook includes a pin and a channel for the beam. The hook may have an extended part, in many instances, that extends just above the channel. To assemble such a hook with the rack or rig, the hook is rotated so that the channel is out of the way of the beam. At such time, the pin is extended through a corresponding opening or aperture in the beam. Once the pin is inserted, the hook is rotated so as to direct the channel over the beam.\n\nIt will be understood that safety and strength of these brackets is paramount. In some instances, the lifter may be in a very vulnerable position and potentially exposed to extreme bodily injury if a bracket fails.",
