This is definitely a heavy duty cover - much better than any tarpaulin i have used in the past.
I didnt measure the cover as it was the largest one available and based on the picture, i thought it would be ample size for my run. This was my mistake. Its not big enough a cover for my run.
I have the standard, single tier zippy run and this covers the roof and one side (2panel side) which is great for now but after my extender kit arrives, this cover wont be big enough to cover the roof. I am extending the basic zippy single tier by 1 in length and width.
Overall, sturdy cover and sturdy ties but measure first.
The cover is big and strong but I have used it to wrap around the end of the run to protect from driving wind and rain so an extra bungee along the centre of one of the long edges would be an improvement as it sags in the middle. Other than that it’s superb.
