GS38 compliant Electrician's Test Probe, Tip Shrouds (the cover that goes over the end of the probe leaving just the tip exposed)
Fit's most standard 4mm 'lantern' type test probes including Fluke, Megger, Robin, Silvertronic, Kewtech, Seaward, Cliff etc....
The price is for 3, all in black. Made with a semi-flexible synthetic rubber insulating compound that grips the 4mm lantern tip.
It's always worth carrying some spares, because the NICEIC inspector will expect to see them. (we all know how easy they are to loose)
