Pulley ReviewOkay for laundry or light duty. I put up two sets (of 3 & of 4) to lift our bikes off the garage floor during winter. Tested my rigs & they work.I’m not worried the pulleys will fail. Would give a better review except they are very noisy & add more friction than I expected. You can see I used good quality line, not too large for the pulley. A better bearing would help, but that’s another class of pulley. If I buy these again I will get the larger capacity, 25 or bigger.

I used it to create a pulley system for a 16' canoe and have not been disappointed. Highly recommended.

Purchased this for my aging mother who loves to feed her hummingbirds but cannot climb up and down the ladder to access the feeders.She received the pulleys the day after I ordered them. She said they are the perfect size and we are looking forward to putting them to use!

Check out the line/rope that you plan to run through it and make sure that this size is appropriate- I used 1/4" line and it works fine. When I ordered, it said next day delivery and it was instead 2 day, but it was still quick. As advertised- simple, well constructed; these are not large pulleys, but they are great for the "reel in" system I used for my small Sunfish sailboat. Open question is whether they will hold up in the water 24X7X365. I suspect that they will.

I wanted something weather proof to raise my ham radio antennas. These pulleys are good quality and are well made. They don't feel cheap at all. Worked perfectly and made the task as easy one. Highly recommend.
