Welcome to our forum.
Simple fix is to expand the outside tubes of the cover lifter they are self tapping screws. These lifters are fully adjustable . Worst case you might have a screw hole showing on the side bars.
I concur with Chas....Sell it and buy a real spa! FYI...Hot Springs is the #1 seller,and over-all,the best spa you can get for your money. .
Why are they giving you the "biz" about your spa? What kind is it, if I might ask? (I ask 'cause it looks similar to mine! )
I think you should ask for a new spa.Just move the thing. It's totally on wrong, but if you simply moved it a couple of inches you should end up with two or four holes to plug. What I mean is: slide it over one or two screws and use the existing screw holes but in a different hole on the bracket.
Bill you don't have to move the brackets, just take out the 3 screws on both side arms that have the little black plastic caps on them, slide the center tube to be even slightly back from center then with your drill gun reinstall the self tapping screws. I am having a bit of a problem seeing if the screws are there at all in your pictures which would not only cause this problem but would let the lifter twist and be harder to open.If you need some of those self-tappers PM me with an address and I will toss some in an envelope along with an instruction sheet on the lifter install and mail them to you.BTW, if you put a straight-edge along the back of the spa and then measure from the center of the pivot hole to the straight edge you should be right about 4 inches.
