What are the “massive constant force springs” that the RollBak has?
Basically, the springs located at the core of the canister are always trying to retract the cover completly back into the canister. So, when you pull the cover towards the canister, the pressure of the springs are trying to pull it back into the canister. Our springs are guaranteed to retract 10,000 times. That means if you were to open your RollBak tonneau cover every single day, the spring would work perfectly forover 27 Years! Do you think you’ll have your truck that long? That’s why we say, our cover will outlast your truck!
