I am affraid the Brandrup ones are with velcro (please correct me if wrong ) when i was looking for the side door net it was velcro anyway sold by Brandrup.
I got myself the one from Maxxcamp for the sidedoor and they come with sewed in magnets and i'm very happy with it.
Don't know if the sell the rear door also.
Lots alllready been discussed about fly-nets /screens , many just done some DIY .
Thanks Hotel California
Yep the Maxxcamp style was the one's I'm after, no need to put Velcro tape all around the doors.
Hopefully someone might have a set they no longer need.
