The pros: Very strong with heavy loads and people easy to raise and lower.
Cons: Heavy to carry and the end caps prevent proper operation of the ladder stand offs we use that mount to inside the ladder rung holes.
We had to modify the latter be cutting off the inside rung caps. (Gutter protection is very important).
Recommend 2 people for set up.
Had a few spots on the side that were damaged causing small shards of metal to stick out. One of my workers cut his hand on it. Not real bad, no hospital visit or anything. Other than that, it gets the job done.
