Suits Carefree and Dometic awnings
Here is your complete guide to caravan anti-flip kits in Australia.
How to select the correct size Aussie Traveller Anti-Flap kit for your caravan or motorhome awning.
Many people select the wrong size of anti-flap kit, because they measure the wrong part of their awning. They also measure the awning when it is incorrectly setup.
There are 3 sizes of Aussie Traveller Anti-Flap kits:
The length dimension refers to the "Nominal Length" pictured here.
All awnings vary in "extension" length. It depends on the brand, and also the year of manufacture. You MUST measure your ACTUAL awning when on the van to get this dimension correct.
Correct Awning Extension - Not Completely Rolled Out
IMPORTANT: Note here the rotation of the roller tube. The first "roller tube polyrod" (which is where the awning vinyl first connects to the roller and normally has a plastic type spline) is NOT directly up.
If you FULLY extend the awning, the roller will be rotated clockwise a bit further than in the above diagram, resulting in a "gutter effect" as below. This is extended TOO FAR, and needs to be rolled in a bit so it looks like the above. The problem with the gutter effect is that water will pool in this area, and eventually leak inside your annex wall.
Incorrect Awning Extension - Completely Rolled Out
Based on setting up your awning correctly, the diagram below shows how the anti-flap kit fits. You need to measure this dimension to select the correct anti-flap kit length.

Curved roof rafters fit in the middle of your awning to raise and tension the vinyl roof. As a general rule awnings lengths:
As an added bonus, when positioned appropriately, the rafter can give you a bit more height over your door so the top edge of the door doesn't rub on the vinyl roof.
There are a few different types of curved roof rafters:
Over extended durations (months/years) the curved rafter will tend to stretch the vinyl roof, but by that stage, the awning is probably due for replacement anyway.
