Monument 3240U Tap Backnut Spanner Set & T-bar Grip

This is a set of three double-ended box spanners complete with a tommy bar. A great problem solver, that saves a lot of time and frustration when it comes to gaining access to tap back nuts. The set comprises the following sizes: 8 x 10mm, 9 x 11mm and 12 x 13mm. Each is approximately 150mm long, to fit over an extended threaded stud. The Monument 3240U box spanner set is just the job when working in those awkward under sink areas.
