Tap Backnut Spanner 1/2" - 3/4" is rated 3.7 out of 5 by 21.
Rated 2 out of 5 by from Doesn't fit I bought this, a 1/2" and a 3/4" brass backnut, all from Toolstation. The spanner fitted the 3/4" but not the 1/2". I shall be returning the spanner.

Rated 1 out of 5 by from It is definitely not 1.25 inches Bought this 04-Aug-2019 from Bracknell branch. Packaging says it fits most 1 1/4 inch back nuts but the item is marked 46x50 mm which is 1.81 x 1.96 inches.

Rated 2 out of 5 by from Not 1 1/4" It's 1 3/4" Seems good enough but advertised as the wrong size. Even the Markings say 46mm - roughly 1 3/4 " not 1 1/4. Reviews are aggregated from smaller sized product.

Rated 4 out of 5 by from Spanner that removed backnuts Picked one of these up today as the telescopic spanner i had was too awkward to get a cross threaded nut off bath taps (yes, the furthest one away) No bar supplied with this, which is a bit poor really, but improvised and this tool mated snug with the brass nut and with some profanity and aching wrist, the offending nut came away. Used much easier on 1/2 in plasric nuts on basin taps so can confirm this tool is as described.

Rated 5 out of 5 by from Good quality Bought this to remove and replace the waste on my bathroom basin. The metric nut came off easily with this tool just what the doctor ordered. However the replacement waste had an imperial nut !!! This nut being 2 1/ 4 af was just oversize so proving the spanner was correct to size. Judicious use of a file soon had the offending nut to metric proportions and everything reassembled. Great spanner for tight locations.
