From Anritsu - What is this? Grounding Rod? Probe? Curious!

Does anyone know what this is? It came from Anritsu but i’m not sure if they made it or what it even is? Is it a probe or something for grounding? Hopefully someone has seen something like this.

Edit: Added one more image.

Temperature sensor?

I just wish I knew for sure, lol. I tried looking into Anritsu Temperature Sensors but didn’t find anything similar.

Looks like a shorting plug for an old cathode tube TV. Before doing repairs the HV charge held inside the tube should be discharged before disconnecting the HV lead. The edge of the rubber flap can be lifted up and the round probe end slid in to make contact with the electrode while the clip is connected to a good ground to bleed off the charge. Then the electrode can be extracted using the rounded end without scratching the glass (such as a flat blade screwdriver would do). The TV tube might be sitting at 10 to 25 kV, so the handle is made of some really good insulator material.
