Review on Erickson 06845 Black 36 Inch Industrial Bungee Cord - Pack of 4: Durable and Reliable Bungee Cords for Industrial Use by Kevin Williams

Good elastic cords are very hard to find. 65% junk and 30% only weak. It's 30%; They look strong, but it takes little effort to push them to the limit. For example, these Ericksons require 8# power to push them to the limit. This means the wind pulling on your tarp doesn't have to be very strong to maximize these bungees where they lose all effectiveness. A good bungee will withstand at least twice that force or more (20#), and a great bungee will withstand 32#+, which is 4 times the holding force. These Erickson bungees are like a four year old child pulling on a rope compared to an adult. I will look elsewhere for more bungee.
