Do these fit other hard hats or just JSP ones; thanks in advance

I've tried them up with 3 different hats none of which was JSP. They've fitted all of them but in some of them didn't snap while mounting them into the slots in the hats. As a result, they can slide out with time but it wasn't a trouble for me. Just had to mount it again.

Please can you tell me if the defenders can be rotated around when on the hard hat I assume they can be, but it doesn’t actually say they can be.

Yes, they can be positioned on the top, front and or rear
