Hi, I purchased the 3.3mt cleva cover and I will say it does need something to attach in the middle due to being a slim long line. This causes a fair bit of slack in the middle.
Very happy with the quality of the cover.. was so glad that the cover is adjustable to suit any long clothesline with various holes as our clothesline is slightly smaller then the cover but still fits great :) would highly recommend this product to protect your clothes all year round..
As we are in a rental with a small line I opted for the larger cover and we structured an additional frame to create a waterproof shelter for our bicycles!
So impressed how the clothes still dry so quickly and no more rushing home if it rains as the cover keeps it dry.
Easy to assemble and all around great product
