K-Key 4000A service with portable generator

[jar546]

Is anyone familiar with these "Kurt Keys" for ensuring disconnect between a portable generator and the MDP of a 4000A service?

Don't know if it is Kurt Key, or Curt Key or Kirt Key. Have no idea, no specs given.

Apparently it is a "Kirk Key"

Need to contact Sq D to see if this is authorized

It is a surface mount or bored lock and should not void any warranty
