Rothenberger Tap Backnut Spanner is rated 4.5 out of 5 by 27.
Rated 5 out of 5 by from box clever with this spanner When you can only get one hand in the space a basin spanner will not help. But!, with this box spanner you can do the job one handed. I purchased this spanner to change our bath mixer tap and only had a confined space,This box spanner undid the back nuts and retightened the new ones no problem at all, brilliant piece of kit. Also it stopped a lot of swearing and cursing!.

Rated 5 out of 5 by from Back it spanner Purchased this item when changing over back nuts on sink taps. So much easier to use than an adjustable spanner which can be quite tricky to to you in the limited space under the sink. Well worth investing in and made the job so much easier

Rated 5 out of 5 by from Tap back nut spanner Real well made tool, and really handy for tightening back nut on cloakroom sinks where space is limited for tooling.

Rated 5 out of 5 by from Beauty backnut spanner A proper tool that does its job well! This is my second, the first one beat me in a game of hide and seek!

Rated 5 out of 5 by from Great Tool But Expensive A bit of a steep investment for the DIYer (as you don't your replace taps very often) but effective and well made. Was the only tool that could reach in a tight space to properly tighten the bath tap back nuts. Wasn't enough space to insert the Tommy bar but could get enough torque using my hands.

Rated 5 out of 5 by from Great Tool Had mobile taps on a basin and would have taken hours getting off wall and replacing. With this, it took 5 minutes including isolating, disconnecting pipe tails and reconnecting! Brilliant

Rated 4 out of 5 by from Backnut spanner Does what it says on the tin but be aware that both ends of this tool is too large for the brass 1/2" backnuts sold by Screwfix, hence dropped two stars on features and overall ratings influenced by this. Works fine for the plastic backnuts supplied with Screwfix basin taps.

Rated 4 out of 5 by from Sorted in 5 minutes Struggled with various spanners, wrenches including much more expensive tap wrenches to remove bottom sealing nut on water inlet valve on cistern. Got this in less than 10 minutes from local Screwfix. Old nut off. New inlet valve fitted. No leaks. Less than 5 minutes. Saved a load of grief on a Sunday afternoon from the Mrs. Did what it was supposed to at a fraction of the cost.
