### ⭐⭐⭐⭐⭐ Review
*by A***L on 5 September 2023*

Purchased this for my extension ladder to attach a rope and it fit perfectly onto my ladder and looks to be a sturdy pully. I bought the rope they suggested for it but was a total waste of money, have to buy a different one that can be tied into a knot and stay into a knot, the suggested one won't.
