About RunLock
RunLock is a braided polyester rope whose two halves are braided together every few centimetres and run free in between. Every free stretch is a loop, and every lock is the rope through one of its own loops: no knots, no hardware.
- 100 % polyester, nothing added
- Washable, does not rot
- Shorten: cut across the middle of a loop. Extend: join two ropes loop to loop
- Braided, tested and packed in Tösse, Sweden
