Bought the Model 32 for 11-14 foot ceiling. Received all the parts, etc needed with the ceiling cover received damaged (most probably by UPS). No problem. Called Customer Service and they sent a new one directly. When all parts came in I got to working on putting the upstairs and downstairs pieces together. No issues. Then, I got a contractor friend to put the whole in the ceiling, making sure that the framing was done correctly. We then lifted the head assembly and made all the adjustments to secure it and assure it lifted without obstruction. All in all, the install went smoothly, taking about 6 hours or so.
