anyone know where to get the Lance roof grab handle?

My camper has a ladder but nothing to grab onto to actually get on the roof which makes it pretty dangerous. I was checking out some videos and I see that Lance has a nice grab bar but I don't know where to find it. Was hoping someone would know where to get it.

I couldn't find a picture but if you check the video below at the 3:10 mark is what I'm talking about
