This rope uses our ultra-light but strong 4" LDPE handles that have been modified to accommodate the attachment of our new patent pending tear drop ball bearing and swivel system. Our custom made replaceable ball bearings are machine screwed and thread-locked to the handles to prevent the bearings from loosening. Loop locks allow for easy length adjustment by the user - no special tools required (wire cutters are required to cut to length). Handles have our limited lifetime warranty. Bearings have a limited 90-day warranty. For PVC options, see the PVC version.
