Something else while your at it. During a recent sudden high wind, went to roll in the auto awning. The U- shaped storage arms didn’t line up by about 1/4“ ,at the top. Had to use a large screw driver to force them in to line up. Once home unfurled the awning and saw it had shifted all the way to one end, causing it to skew and wind up crooked tugging the arms so that they didn’t line up. Lots of soapy water to lube and tug the 18’ awning back in place on the roller tube. 2 stainless screws on each end should now hold it from shifting again.
