The Monument 3240U 8-9-10mm & 11-12-13mm Mono Tap Back Nut Spanner Set is designed specifically for the tightening and loosening of the nuts used on modern Monobloc taps. These nuts are found at the base of the taps and thread on to exceptionally long tails which makes these long (175mm) box spanners the perfect tool to carry out the job effectively. The set contains three double ended box spanners and includes a tommy bar to help apply extra pressure when needed. Box Spanner sizes are 8x10mm, 9x11mm and 12x13mm.
As an accessory to the Monument 3240U we have designed the Monument GRIP+ 4562P Step tools which is a set of two 3-Step Hex Fitting Tools made to fit 3240U 8-9-10mm & 11-12-13mm box spanners allowing improved access when tightening or loosening Monobloc tap backnuts. This Monument Grip+ setis one of a number of tools making up the innovative advancement to the bestselling Professional Adjustable Basin Wrench 345V. The step tools fit the swivelling head of the 345V wrench and one end of the box spanner thus lengthening the box spanner. Please see 4562P."
