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 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.
