Rated 4 out of 5Â by steve1951 pretty good tool
Fitted well - I have tried the flat spanners before and they do not work and you have to cut away a lot of the tank insulation. The tommy bar is not really long enough - we are in a hard water area and the old heater had been there 20+ years. But using a long pair of heavy-duty grips to hold the box spanner got it moving. I read that it is best to leave the water in the tank while trying to get the first movement on the spanner - water adds to structural strength of tank and reduces risk of damaging it - of course drain before taking it right out!

Simple tool - does the job well.
Good value even if you only use it the once!

Rated 5 out of 5Â by bugbug great immersion box spanner
great box spanner , the length of it keeps it away from fouling on pipe work that might be in the way and the tommy bar gives good leverage for removal and refitting immersions

I found this spanner slightly too big for the immersion heater nut and unless you're very careful it will drop completely over the nut and dig into the copper cylinder while turning it. Had to go back to my flat immersion spanner which easily undone the immersion and was far more controllable.
