I love this product but I don’t think it is 4 ft by 10 ft if I stretch it to 10 ft then it has a height of around 3.5 ft . My fence is of 30 ft x 4 ft and two sets could not cover it totally three sets will be perfect however, I did not buy the third set yet because the prices have increased to 250 cad I got the initial two sets for 150 per set Canada day sale. Waiting for sale.
