I'm a high school science teacher and one of my biggest laments is not being able to SHOW the students the science we teach sometimes. This pulley will allow me to do so. It is a simple table-clamp pulley so it may not fit on all tables, but it will allow me to demonstrate and show the students how a pulley changes the force's direction when applied.

I needed some pulleys with a wide enough clamp ASAP. They aren't entirely frictionless. Used for makeshift Atwood machines for my freshman students and they mostly performed smoothly. I think I bought 6 of them 2 had more friction than the others. Might have some issues using for masses smaller than 50 grams. I'm glad I got these over the other options though (it's been a while since I purchased these on Amazon so don't know what else is out there). Keep in mind I needed these asap. These will do the job. If you want to have more precise demonstrations you'll definitely want to go with something that has ball bearings or something other than a plastic cylinder sleeve on a metal axle for example. Overall I was satisfied. The clamp quality was decent and I was able to get a good amount of torque on them. They seem pretty durable I think they could last years for a repeatable class lab experiment.
