I was going over the install instructions yesterday and realized my lift is also 220v. Good thing I hadn't run those lines yet.Agreed. Add a 220 line in. I am doing similar to you and also have a bendpak lift. The 220 version costs no more and operates faster so I got the 220 version.
Studs are covered now so too late. I could nail 3 2x6 horizontaly to spread the load across more studsPrincess Auto sell similar units, cheaper, all made in China, of course.
If studs are exposed, you could 'sister' them to become '4x4 or 6x4'
Had 1200-1400# of maple flooring on 5 homemade 'brackets' (2x4s), 2' from wall, ZERO issues
