I was able to pull 4- #10 solar power wires through a 2\" conduit with a long sweep 90 degree bend at both ends. Great value for a good quality product.
I have never used it before, mostly fiberglass. I don’t know how long it will last, but the guys said it’s a useless thing. It's better to buy from Klein Tool and use. But for the money it sits well on the shelf.
Tried this out the other day and it was light weight and performed well in a short conduit. I haven’t tried longer yet but expect it to work just the same.
As a cable tech I run my line through smurf tube everyday. Sometimes these tubes are jacked up, missing a string or the string breaks. This bad boy will glide through 99% of smurf tubes with minimal pushing.
