Immersion Box Wrench is rated 4.8 out of 5 by 12.
Rated 4 out of 5 by from Does the Job A very sturdy tool, that did the job for me. One weak point in this is the Tommy Bar. As anyone who has removed an Immersion heater knows, it's not a easy task. The Tommy bar bent with me, as I had to use a length of pipe on the end of the bar. I ended up with a Blow Torch and a few solids hits on the side of it, to free it, but I don't believe the Bar is strong enough on it's own

Rated 5 out of 5 by from Boxed off Bought this to replace am immersion heater. Glad I did! Didn't have a spanner big enough and this boxed the job right off.

Rated 5 out of 5 by from Good Solid Construction I purchased this wrench to remove an immersion heater that had been in place for probably 20 years or more. It was still difficult to remove and a longer T-bar would have been helpful - when an extension tube was attached the T-bar started to bend. I managed in the end by using a long 1/2" bar so generally a good product & certainly no problem with the wrench itself.

Rated 4 out of 5 by from Did the job The heater I was replacing had been in place for around 60 years, so was well bedded in. Initially, I couldn't shift it. sliding a 2ft length of steel pipe over the tommy-bar gave more leverage - but the tommy bar bent, while the heater didn't move. Replacing the bar with a 1/2in steel rod finally allowed me to extract the old heater. Through all this, the box itself gripped firmly, with no hint of any slipping round the nut
