Over many years of selling battle ropes, we have found that the typical tug of war or shipping ropes when used for BATTLE TRAINING simply fall apart. We changed to using Dacron Ropes and find that we have had very few issues with them due to the way the ropes are designed. These ropes are able to withstand years of shaking and slamming them on the floor over and over again on a daily basis. Why not call us for more info regarding our BATTLE ROPES and we will help pick the product that will suit your needs!
