Has anyone used the racking systems on van roofs that prevent the need for someone to use stepladders to get their ladders down or climb on the rear wheels (which happens)! I have seen various products that can be pulled down from ground level and put back up using the same method, eliminating work at height and reducing manual handling.

If anyone can put me in touch with a supplier or recommend someone to get in touch with re costs etc. it would be appreciated. We have a few vans that I would like to see fitted with these systems and I need to put my case to the directors.
