Harken Hoist installed! I have a roomy unfinished garage with a 4 foot deep shelf that hangs down along the rear and side of my garage.
The hoist was straight forward to install, though all the work over my head tired out my shoulders. The toughest part for me was knotting the ropes. I was never a Boy Scout and knots are not my thing. Thankfully my neighbor helped out.
I will shorten up the straps a bit to level out the top, and I will move the four pulleys forward an inch or so, this will allow the rear window to miss the angle iron that holds the shelf up.
The hoist itself easily lifts the top and the locking mechanism is simple and strong.
if you have the space it is a really solid solution.
