manual crank for electric tongue jack?

[MillMitch]

Hey guys,
I have a 2018 Grey Wolf 23MK and the front storage was broken into a couple weeks ago. I've replaced everything that was taken, but am having a hard time with the manual override crank for the electric tongue jack. I carry a socket set, so would like to replace the crank with a socket, but can't figure out what shape the head is. Hex? Splined (like a gear, not sure that's the right word)? normal 6 sided socket? thanks.
Regarding the breakin: I no longer keep anything in the TT that I need to hookup the trailer. They took my E2 snap up tool, and the pin for the hitch receiver; plus some other metal items immediately behind the door.

thanks again,
Mitch

Lippert jack? If it is there is a rubber grommet on top hiding the 3/4" hex override.

Thanks. Not sure if it's a lippert, but there is a grommet. I'll look for a 3/4" hex.
