Ideal for Drayton lock shield radiator valves
Fits Drayton radiator lock shield valves. Can't grip the Drayton knob so remove screw & knob and use this instead. Perfect fit, much easier to turn.

Works perfectly with square Drayton TRV4 lockshield valve shafts.
Speedy delivery, good price, square socket fits the approx 1/4 inch square Drayton TRV4 lockshield valves I use. Much more convenient than using an adjustable spanner.

Good quality
Perfect for an outdoor 1/4" stopcock, . Replaced a red steel handle with this as it won't rust.
