Joe,
I'm assuming that the cover that usually fits on the front of this disconnect, would make the operating lever even harder to get at, once fitted. [Linked Image]
One way you could do it, is to slip a piece of tubing or pipe (with the end flattened slightly) over the operating lever.
Not the best solution, but what else can you do?(apart from getting the idiot that installed it with his eyes shut to move it or put a longer lever on it). [Linked Image]
