I just bought a 20 ft. extension ladder and it came with a rope and pulley system. How do you operate this. If I untie the knot, it seems like I can just push the ladder up and lock it in place. Is the rope just another alternative to extendind the ladder or is it a safety mechanism that I need to do something with. If not, it is necessary to tie the rope around one of the lower steps after extension to secure or just let it dangle in place.
Thanks for all the advice.
