National Hardware N220-020 Fixed Eye Single Pulley 3 in Zinc Plated Steel Heavy Duty Rope Pulley System for Lifting Indoor Outdoor Applications 650 lbs Safe Working Load

Seems to be of good quality only time will tell.

I have a Jet dust collector JET 708620B AFS-1000B 550/702/1044 CFM 3-Speed Air Filtration System with Remote and Electrostatic Pre-Filter that I wanted to fly over my table saw. I wanted it high and out of the way when not in use and also be able to lower it down to the table saw if I was sanding boards and wanted to suck the dust up. I put an electric cable hoist against the 15-foot ceiling and let the cable come down and through two of these pulleys and then back up to the ceiling. I can now control the height of the dust collector easily and change filters as needed, yet it's out of the way when not running. These pulleys are exactly what I wanted because they don't rotate, allow a bolt to go through the eye and have a removable pin so I can thread the cable through the pulley and then replace the pin. They are simple and strong. Exactly what I was looking for and they work great.

For $10.50, a great value. Works with 1/2" rope. Also, try to find these locally. Near impossible. I rated sturdiness as 3 star because I can't actually test function at the claimed 650 pound working load but I assume it is true. It will handle a LOT of load. The rope groove in the pulley wheel is deep and round-shaped; excellent for use with rope. The bearing is just a sleeve bearing on the pin; simple, effective but will produce more friction than a roller bearing at high loads. For general use it is an excellent product. I bought two more just to have around for the next "need a pulley now" project.

heavy duty, and very smooth. I bought a pair of these to hang from my celing in the garage to hang weights from for doing lat pulldowns, triceps, etc. my only complaint is that it is hard to get the pin back into its hole after removing the wheel from the housing to put your rope or cable through. i ended up putting it in a vice to hold it together while i got the pin through, but that is the last time i will have to do that, so not really a problem for me.

I originally bought four National 1 1/2" double pulleys to rig an eight-pulley block and tackle using 3/8" poly/nylon rope, but the system had too much friction and didn't operate smoothly. I replaced the pulleys with eight National 3" pulleys and now it works great. It is rigged for a 7/1 lifting advantage, ignoring friction. I just built a new garage that was designed with a 4' x 4' opening in the ceiling and floored above for storage. I use the block and tackle and a lifting platform to move stuff into and out of the storage area. I have to pull a lot of rope (about 90') to lift or lower the platform, but I can move heavy items with ease. I did a lot of looking before settling on National pulleys and found them to be the best quality per dollar out there.

It is a nice quality pulley, i bought a few more for my rigging box. The wheels spin smooth and easily under load, the hole on the top is reinforced by rolling the steel a little so it looks like it is solid. And the pulley wheel removes so you can attach it to a lead without having to thread it in to the pulley before hand. Overall it is a great pulley and for a good price.

I once had a frozen shoulder, so my doctor sent me to one of those medical exercise centers. There, they had me pulling on rubber tubing and weights on a pulley. The cost was outrageous and after I learned the routines, I decided that hey I could device something at home that works just as well and won't cost me $45.00 a visit. First I went to Ace Hardware for the rubber tubing ... OUCH, it was expensive! $2.00 a foot, but still cheaper than the center. Then I went to Home Depot for a good pulley. However all they had were these cheapos which squeaked a lot and full of grease to keep them lubricated. The problem is the grease turned black and it got all over the rope I was using and onto my hands and ..oops my shirt. Aaaagh! A couple of bodylastics handles and I was good to go. The squeaking woke up my neighbor a couple of times since I set these up in my back porch, and I do all my bike riding (5 miles each day) and my exercises very early in the morning. About 7:30 a.m. So, I decided to replace the cheapo with this pulley and the thing is very quiet and works smoothly. I may be purchasing a couple more just for the heck of it ... LOL! Who knows, I may find other uses for it.

These pulleys are great and are easy to pull the rope for bikes. I use a pair to make it easier.
