You can almost guarantee the stopcock will be in the most awkward spot. Mains stopcocks are often located in a dark recess at the back of kitchen cupboards or under the kitchen sink or maybe it’s just an outside tap that's too stiff to turn. This mini stopcock key gives you that necessary extra bit of leverage. It has a crutch head design and a removable tommy bar (or you can use a 13mm socket or spanner on the hexagon shaft). Overall length 225mm, to fit stopcocks from 1/2" upwards.
