This innovative product from Armeg is designed to make a plumber's life a whole lot easier. Fitting or removing unsighted taps can be a fiddly and frustrating job, which is where the Jaw Dropper Spanner becomes exceptionally useful. With the sliding jaw locked in position it allows tightening or removal of the pipe union nut. With the sliding jaw dropped it allows tightening of tap back nuts without having to turn off the water and drain the system. The head is practically self guiding and locates with ease onto the nut, a swing out handle aids tightening or removal of basin or bath nuts. The set, contained in a carry case, consists of two spanners, one for 1/2" and the other for 3/4" BSP threads.
