Last year on August 16th Cody the star of “Wrangler Star” you tube channel posted a review of the Nifty-Lift block and tackle pulley system lifting a generator high enough to load into a pickup. He explained that it was made of solid aluminum with stainless steel fasteners. He also demonstrated the strength of the hi-tech parachute cord that has a mil-spec break strength of 1,700 pounds per strand.
Ever since his review the folks all over the world have been ordering the miniaturized rope block and tackle for everything from snowmobiles to four wheeler s, to tree work, bug out bags for survivalist, to cave exploration.
All I can say is I had no concept of the power of the internet.
