Pivot Shoe Info. Needed

A quick learner from New York says:
hi, would like to know what if any advantage there is to have a close "pivot shoe" for a window sash? Having such a rotating cam is very user unfriendly if you try to remove the sash; so could you explain what is going on.Thanks for your prompt response----attached is an image of the closed version of a "pivot shoe".

You can see from the other image that the window sash has been opened to 90 degrees to view
how the plastic housing of the pivot shoe has been slightly cracked away when the sash was

This type of shoe is bewildering to me vs the open shoe as it is so user unfriendly for the layman and
very high risk to have a consumer try to take out a sash with this type of shoe???

thanks and look forward to hearing your thoughts,

Hey, Ronnie. I don't think there's any particular advantage over this shoe to any others. It's just how some manufacturers make them. We don't really find them that difficult to handle, though. It just requires you to twist the sash when you remove it from the window. Also be sure to raise the sash a few inches before tilting it in, or you will cause damage to the shoe or even the sash itself. See our video below to get an idea of how we remove the sash for this kind of window. As you can see, it just takes one twist.
