## Customer Reviews

### ⭐⭐⭐⭐⭐ Great for gym pulley replacement. Excellent quality.
*by J***M on May 25, 2018*

I build my own gym racks and such, i had been using the pulleys from home depot and they would last about 3-4 weeks. THis pulley is indesctructable, ive now had it for 6 months and its going strong. I use it for lat pulldowns and cable rows with 200+ pounds and its smooth as silk. It's quiet and feels like it has incredible build quality.

### ⭐⭐⭐⭐ Great pulley, great price!
*by R***T on March 25, 2016*

Installed on a dog run with both a full sized Boxer and full sized American Bulldog.Smooth, quick, quiet, very low drag...One note: I recommend using Loc-Tite or comparable threadlocker on the only removable screw, as it will inevitably begin to slowly back out.

### ⭐⭐⭐⭐⭐ Five Stars
*by J***S on March 24, 2016*

Sturdy. Exactly what I needed for my homemade lat pull system in my gym.
