ABSTRACT:
A carpet stretcher of the type which normally uses a rear wall as a backstop when stretching carpet toward an opposite forward wall may be converted into a stretcher which pulls against a forwardly disposed tack strip during stretching if a rear wall is not available or is too remote to be of practical benefit. The converting attachment is secured to a stationary part of the basic tool behind its shiftable carpet-engaging head but extends forwardly beyond the head and terminates in a normally upright blade that catches behind the far side of the tack strip when in use to provide an anchor point for the stretcher. The head can thus be located in close proximity to the blade to minimize the unstretched margin of the carpet as it is presented into overlying relationship with the tack strip.
