This is a great set, but it should come with two prusik ropes.
This is a great set, but it should come with two prusik ropes. You'll probably want to get two more carabiners if you're just getting started as well. One is usually used for progress retention and the other would be used for the load. I used them with 1/2" rigging line and they stayed it very nicely.There isn't much of a manual with these either. I don't think it would hurt to toss in a piece of paper with a few rigging and knot examples.

Just what the job needed
As a solar contractor. I use block and tackles to move heavy panels and tanks in to place for hot water systems. These are high quality and stout. It made moving a 300 lbs tank into place very manageable (along with other blocks).I am very pleased with the convenience and performance of the equipment.

It'll do.
It's best suited for 1/2 inch rope or fatter. The supplied eye-n-eye prussic gets rolled unto the frame opening when using 1/2 inch 12 strand dynamic arborist climbing rope. Not a very good "prussic minding " pully.

Worked great.
Had to load a gun safe into a moving truck. Used the pulley setup to pull up and lower the safe on the trucks ramp. Worked great.

Light weight, compact, yet strong.
Quality of hardware is tops. A page illustrating alternative ways to use the system along with how to best care for it would make it 5 stars.
