The Jackhammer Support Arm is a labor-saving device for electric jackhammers and other heavy power tools that supports the weight of the tool, allowing for total concentration on the job at hand. It has three setup options—tripod, scaffold, and shoring pole—each of which takes less than five minutes to assemble. Removable pins hinge each joint, making the device portable. Its universal clamping system allows for the attachment of most hammer drills. British Columbia Institute of Technology – BCIT. 604-434-5734.
