Relieved to hear this....our Vango Palm always tries to work its way out of the rail even in the best of times. Thinking about it, so does our Debus Canopy but we use the little Kampa Rail clips in the end of the rail which stops them escaping!No problem, it was the Kampa trip air, no damage at all, used screw in pegs, so it was just the constant tugging that worked the plastic along enough for the Kador to pull out of the end and then once it started it carried on.
