Mann4ducks,
Here are some more photos. The bottom of mine is 56” from the rafter. I have 60” clearance then to the ground. If you had shorter straps with loops on both ends, you could get a few extra inches higher on the lift. I used the stock straps.
I would note, there bike models and kayak models at Fleet Farm. I think the only difference is the additional straps for hugging the kayak whereas the bike model only has the hooks. Hooks-only would make it very tough to raise and lower.
Let me know if u need more pics.
