Heavy-Duty Double Block and Tackle Pulley System – 100Ft x 1/2'' Rope, 7700 LB(35KN) Breaking Strength, 4:1 Lifting Ratio – Ideal for Garage, Attic, and Heavy Lifting Applications

Great rope great Pullys . Rope alone worth the price

I used this to pull the top of a tree in the direction I wanted it to fall (it was not a huge tree). Looped my bull rope around a solid limb near the top of the tree (using my throw bag and throw line), rigged the block and tackle to a solid (separate) tree near the base (using a couple of slings and a locking carabiner), rigged the block and tackle to the bull rope using knots and a locking carabiner. Took the slack out of the rope and applied a little bit of preload and 'locked' it with a stopper knot. In theory this keeps the top of the tree from falling backwards. Then made the notch cut and pulled on the running end of the block and tackle just enough to test the geometry. Finally made the felling cut (leaving a large hinge), then pulled on the running end of the block and tackle (made myself a loop) and it easily pulled the tree over in the 'right' direction. Much more convenient and more travel than the 'come along' winch I have used before. I was also further out of the path of the tree since I pulled at 90 degrees to the anchor tree. The block and tackle system does come with instructions but I am not saying they are clear. I am still learning my knots. The pulleys are really smooth and pretty. The rope isn't amazing but is very adequate for this application. I ordered a duffel bag and plan to store the block and tackle all set up, separate from my other ropes.

Very good quality. I have had to move some very heavy logs up a hill. This worked very well. No issues

These are really well made and should last a lifetime.

The weight and performance of this block and tackle have been really good. I use it to lower and retrieve a 150lb boat on a roller ramp, over riprap. Anchored to a tree with a tow strap, and it makes the job easy!

Well made and highly functional. Rope is a bit stiff for the application.

This was a nice upgrade for my attic block and tackle. My existing one worked but the cord was a bit small and hurt your hands if there was appreciable weight. This larger 11mm rope hurts less if you’re hoisting large weight.

Hauling and balancing heavy items with your hands up an attic drop-down ladder is dangerous. Using the Greteefor Heavy-Duty Double Block and Tackle Pulley System, I was able to solve that problem with ease. I used some scrap 2x4 lumber, glued and screwed its components to make a frame, and then lifted those large bins and storage items safely. I selected this lightweight pulley system and tested it by lifting air compressors and tool boxes weighing more than anything I would store in the attic. The thick rope and aluminum pulleys with roller bearings made the awkward size of heavy bins and boxes a simple solution. My seasonal storage capacity increased due to the ease of use of my handyman design. I bolted the base of the frame into the attic joists/floor for stability. The result was more room in my garage. If I move, I will remake another hoist system and take the rope and pulleys with me. It is not intended for lifting massive things like the weight of car engines or transmissions as I am not an engineer. Before use, I uncoiled the 100' long rope on my driveway in the noonday sun to unravel it. No kinks. No knotting. I highly recommend the Greteefor system.

Worked great. Needed to lift a new staircase into place.

Gute Handhabung . Laufen sehr leicht.

Very good construction smooth finish. smooth bearings. And they look and operate in a feel of quality. And of course this combination reduces the strength need to lift things.
