JCBIZ 1-Pack M50 Single Pulley Block Stainless Steel Heavy Duty Hardware Single Wheel Swivel Rigging Lifting Wheel Fixed Pulley For Wire Rope Loading 400kg

Excellent item , strong

I use this for my personal gym and it’s still good after a month everyday use! Me and siblings need a pulley for lifting heavy weights. I’m really happy that it works as intended.Pros:- Really durable, even after a few drops.- stainless!!! We sweat a lot and this is a must!- Smooth even after lifting with 70lb+ weights.Con:- Buy a W4 to keep it smooth and to keep it silent. We have to spray some every other weak. But works really smooth.

They are your basic pulley. Not rated for every day commercial applications. They are a little noisy, but well made.I have a 4-pulley combination to lift heavy items into the attic.It’s amazing what you can lift with this set up.

I use this as a pulley for my gym equipment. It makes a squeaky noise at times, but it holds up pretty well. I use an assortment of weights and haven't experienced any downsides yet. If something changes, I will update. In the meantime, I would recommend.

I use it for home-made workout system with a lot of repetition. I don't think this was designed for constant repetition as it squeaks noticeably and heats up a little. Looks/feels sturdy though and will keep using it until it breaks.
