This Monument 2 Jaw Adjustable Basin Wrench is 290mm long and features a silver steel construction. It is designed for tightening or loosening nuts in awkward positions, particularly those underneath basins or baths. The teeth on the jaws provide a secure grip on uneven shapes. The swivelling head allows access where fixed spanners cannot operate. The solid steel handle has a profiled end for attaching sockets and extensions for longer reach. Correct heat treatment of all components ensures a long life. Made in Britain, this wrench is supplied with small and medium jaws, suitable for sizes 15mm and 22mm (1/2" and 3/4").
