Monument 361T Box Ring Immersion Heater Spanner
The Monument 361T Box Ring Immersion Heater Spanner is made with an octagon at the base of the cylindrical section to enable really tight immersion heaters to be loosened by striking the handle.
The one-piece casting enables full transmission of power to the spanner unlike loose tommy bar types. Overall clearance around the spanner is 7/8in (22mm) allowing easier fitting on insulated copper cylinders.
Made in Britain.

Quality product. Had a few knocks with a lump hammer over the years to shock old immersion heaters out. Much better than any alternatives there are

Super heavy, but works a treat.
Always a risk of damaging the cylinder when removing the immersion.
This locks over and positively engages with it giving good grip minimising the risk of damage to the cylinder when removing. It is just so damned heavy.

Great spanner, it's a heavy well built addition to the toolbox excellent for removing old faulty immersions, you can give it a tap of a hammer to shock the threads without the fear of breaking or bending the spanner.

Nice sturdy immersion spanner key. I’ve got a few other options in the van. Flat spanner, angled spanner and this one. The other ones are ok for fitting a brand new immersion (as it this one) but this one is usually the only option for removing an old one that’s been in foe years

This immersion spanner is by far the best one possibly available on the market . Make life easy by only needing one hand to hold it leaving your other free to give it a gentle tap with a hammer

Excellent tool for the van we have had all other types of immersion heater key and have failed. This is the only key to use.

I prefer this unit to the others as I keep loosing the metal rod you to thread through on the others. It’s handy to have it all as one piece. Again excellent build quality you come to expect from this manufacturer. However sometimes even with these immersion tools they are hard to remove. However a little bit of heat applied soon loosens up any old jointing compound. Don’t force it, just warm it. Obviously with the tank drained and electrics disconnected.

Great price. needed for a single job. The spanner fitted onto the immersion perfectly. The one piece design meant i wasn't hunting for a separate bar, in the mystery tool bag!

Oh my god this is good. Just get one, you won’t regret it if you want to loosen or tighten an immersion heater. The spanner will take it even if the immersion heater boss doesn’t.

Another must have, I’m definitely a fan boy, I didn’t even need a new immersion spanner. But this was so cheap that I couldn’t resist. Perfect tool, works, doesn’t slip, it can take a whack from a hammer. 10/10

This is the one and only Immersion heater spanner you will ever need. Good thing there is no tommy bar to lose and you can give the the handle a good tap with the hammer and nothing will happen. If you need more leverage just cut a scaffold pole to size and slot over the cast iron handle to make it longer.

I have this in my tool box but I couldn't get on with it and converted back to my original, the handle is nice and bulky for a good grip bit sometimes old immersions are too tight and need a bit of leverage, I usually stick some 28mm to the end of it, which I couldn't do with this one. Maybe I should just get down the gym?

I have been using this spanner for years it is very strong you can even hit the handle with a hammer to crack the thread to stubberen jobs. I would even consider buying another one just in case they. Stopped making them.
