Pop top question

Makes sense.. cheers

If anything the lowering of the top creates a PRESSURE in the van and not a vacuum. So it won't be sucking in the skirt at all. With door open and zips closed you won't notice any difference raising or lowering. Most skirts have vertical spring strips to initiate the onward fold and designed that way to make it come inward.

No it does not make sense. When you lower the top you are decreasing the volume of air enclosed in the van. If you pull the top down with everything closed up you will force the skirt outward so as to try to maintain the same air volume.

We totally close the zips as there seems to be dust collecting inside if the zips are left open a bit. At any rate you need the vents closed up so they are not creased by becoming badly folded when the top comes down.

Guess that bungy cord could apply to a windup unit.

Every 6 inches of down ward travel I go around pushing walls inside so they don't get pinched or left dangling outside

Yea the amount of skirt in the windup might be too heavy for a bungy. You could try just wrapping a length of rope around it with a loop and keep pulling it in as you lower the lid.
BTW - I have a mate with one less eye after pulling too hard on an old bungy cord. So please be careful and check for wear or slipping knots.

I would never use "elastic bungy cords" in this method for that very reason.

I have mentioned before young kid was killed after one let loose in karratha centro shopping centre when he was collecting trolleys, first day on job too.

From what I can gather attachment end (hook and coil) came adrift and flew through air collecting him in neck causing major trauma and injury to neck area preventing breathing to occur.

when I refer to bungy cord, its really shock cord like used inside a dome tent pole allowing - this could be somehow tension when fully wound up and then pull sides in as you lower the roof down pulling in side as you go.

I have heard that about the young fella collecting trollies.. very sad..
I had a mate that had to carry his eye ball in his hand, still attached.. for 5 hours, while his wife drove to the nearest hospital.. camped out back, just about finished packing up, when the ocky strap on the roof let fly...
The Skirt seems to fold in neatly, no dramas, no fold marks or anything.. just been told contradicting things... thanks for the replies all.. Cheers Odog

We had an old pop top yrs ago and as mentioned door open and put the hook on it I didn't one day and it pulls you up quick when it slams shut form the suction while pushing the roof up. Always left vents closed with roof down do a lap around the van check the skirts not hanging our then done up the clips.

Use stretch cord around the middle...same stuff as bungy cord without the hooks...buy by the length in different diameters from Bunnings or the like.

Bungee cord (note the spelling) does not necessarily have metal or other hard ends on it. See the link.

I accidentally left one zip undone on my Quantum & when the roof came down it broke the zip slider!

Gidday Shaker,

I have a Q4, and haven't had any hassles at all. Go figure.... I check that nothing is going to catch before I lower the roof. Can't see any potential catch-points....

I couldn’t either, but it happened.
