ABSTRACT:
An extendable support arm for a carpet stretcher is provided. The extendable support arm is a multiple section telescoping arm having several telescoping sections made from angle aluminum extrusions. The angle extrusions all have the same cross-sectional shape and size thereby reducing manufacturing costs and allowing the changing of the total telescoping length by either removing or adding telescoping sections. Gravity-operated locks hold each section in the extended position, while a combination in gravity-actuated and manually-actuated locks allow fine adjustment of length on one of the telescoping sections. Turning the entire assembly over to the upside down position unlocks all sections allowing the arm to be collapsed. A tail block with casterable wheels is provided to allow easy movement of the stretcher within a room.
