Smart Spa Supply Spa and Hot Tub Top Mount Cover Lifter - Industry Standard Design (Black)

Can this work with the cross bar perpendicular to the hinge and rotate cover in one piece and not folded?

Do you have to manually lift one side first and then use the hydraulic lifter when the cover is already doubled over?

Do you sell just the arm? I need to replace mine after it was damaged in the wind.

Are the parts from this assembly interchangeable with the leisure covermate i ? the wind bent all the bars, but i don't want to disassemble the brack
