ABSTRACT:
A hand tool used to quickly and easily remove an aluminum window frame from a window casing that comprises a slide hammer assembly with an adjustable clamp attached to one end. The slide hammer assembly includes a handle that slides longitudinally over an elongated rod. Attached to the proximal end of the rod is a replaceable stop cap. Attached to the opposite distal end of the elongated rod is an adjustable clamp. During use, the elongated rod is perpendicularly aligned with a surface on the window frame. The adjustable clamp is then securely attached to the surface. The handle then slides downward over the elongated rod and against the stop cap to generate a pulling force to the member. Using the above described hand tool on all of the attached members, is a quick and easy method for removing an aluminum window.
