Box Immersion Spanner is rated 3.9 out of 5 by 52.
Rated 4 out of 5 by from Good Quality Seems to be a good quality strong tool, tried it to undo the heater but couldn’t crack it, ended up using a sash clamp which was spot on. Used the spanner to tighten up the new heater and worked well, no leaks.

Rated 5 out of 5 by from Good quality tool Good quality tool. Spanner fitted well over the immersion heater head and the lever is of a good length allowing application of some controlled force to break seal between immersion and tank.
