    Abstract: An add-on leg bracket for a suspended tom-tom prevents tom-tom from bouncing. The bracket consists of a main component that anchors the support leg, and two slotted arms that secure the bracket to the tom-tom. The face of the main component presents three openings: one centrally positioned opening leads to a conduit that receives the support leg; two openings positioned equidistantly from the central opening are threaded to accommodate screws that fasten the arms of the bracket to the main component. The outward facing side of the main component has a threaded opening that runs perpendicular to and pierces the support leg conduit. It receives a thumb screw fastening the support leg to the bracket. The arms are slotted with a closed track to accommodate thumb screws securing the arm to the main component and notched at one end to lock around tension lug on the tom-tom.
