I used them for my son's robotics team **Q: Is there a load capacity on these if you are using them as a pulley?** A: There probably is, the Plastic outer would be the limiting factor as excessive weight would make the cable or rope cut into the plastic. ## Customer Reviews ### ⭐⭐⭐⭐⭐ They were priced perfectly and worked great! *by S***T on November 10, 2017* We used these to build a Roman Curtain style rig for raising/lowering a projection screen in a recent Community Theatre production.
