Rated 5 out of 5 by from have spanner love box I already had a spanner but didn't want to be caught out with a defective hot water cylinder element in a tenant's premises!! As it happens the box spanner was needed as the element was stubborn! Gives you precisely the right amount of feel for the job.Robust tool will last my time out!!

Rated 4 out of 5 by from Tool for the job Well made tool for the price. Could be improved by having a slightly longer tommy bar.

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.
