Very disappointed in this product! When we put it together the bars already had dents and rust on them the cover on top has a letter and number marked on it that doesn’t wipe off! Now the clamps to hold the cover down don’t hold tight enough so they slide up the poles! I would not recommend this product to anyone!  Prior to purchasing the pergola canopy I saw several reviews claiming this was very good at withstanding high winds.  That has not been my experience.  We had normal windy days for Michigan and I just spent 15 minutes gathering up the canopy and several parts that broke off due to wind.  You shouldn’t have to take the canopy off every time you think the wind might blow.
