The PT300 Power Tamp was designed to replaceme the old hand-tamp. Ideal for stamping concrete, the power tamp features an adjustable throttle stop and a kickstand that can be used as an extension handle. It reduces crazing and cracking, does not blow the stamps apart, and is easy on the wrists and hands. The vibration of the tamp produces a high-quality and smooth finish, while reducing hazardous dust. JLIN.
