Sun Roof Hook holder

I was tired because i cant hang my wet things when i am camping with my Campervan. It fits perfect on my Sun roof (Reimo Mauritius L) but it should fit any roof with Pins at the Pols. 
At the Moment i don´t have the Hooks Ready but as soon as i have the perfect hook ready i will post it here. Meanwhile you should find some in the hardware store locally ;-) .
