Frankie Aira tap - fitting issue undermount sink box spanner

[Haggistrap]

Hope you can help. I am trying to fit a Aria pull out tap in a very confined space, from under a worktop with the under mounted sinks. The issue being I need a long “box spanner” or a tool to allow the securing nut to be tightened to the worktop.

Can anyone advise on if such a tool exists, I need a hollow one with enough room to allow the brass screw section to protrude out into the box spanner while tightening. Normal tools even a basin wrench for confined spaces are not able to complete the job.

Images below, the box spanner will need to be long enough to allow it to b tightened ideal below sink level. It will reach the nut in front of the plastered wall but behind the wood support section. It need to be hollow as a pipe must run through the box spanner.

Amy help appreciated!

Forgot to say, the "nut" is 21 - 22mm in size, most mono-block tap box spanners do not go that long....

22mm AF sounds big to me for a monobloc clamp....
