The Monument 349H Adjustable Basin Wrench is a professional plumbing tool designed for tightening and loosening nuts in confined spaces, particularly beneath basins and baths. This British-made basin wrench features the Monument GRIP+ system, offering reliable performance for plumbers and heating engineers working in awkward positions where standard spanners cannot reach. The adjustable jaw capacity ranges from 15 to 42mm (1/2 to 1 1/2 inch), accommodating various nut sizes commonly found in bathroom installations. The toothed jaws provide secure grip on uneven shapes and worn fixings, whilst the swivelling head design allows access where fixed spanners simply won't operate. Built from solid steel with correct heat treatment applied to all components, this basin wrench delivers durability for professional use. The profiled handle end accepts sockets and extensions, enabling increased reach when working in particularly tight spaces under baths or behind wall-mounted basins. Features and
