TRC: Compact form and lightweight functionality, this sewn eye to eye is not only more streamlined that tied knots, but also stronger. Clear tubing allows for easy inspection and protects the stitching. Manufacturer recommended Prusik cord for OpLux, this 6mm specialty cord by Sterling features a durable Technora sheath and a nylon core. Our TRC hitch cords are 23″ in length so that users have the ability to tie more hitch variations. Shorter lengths greatly reduce the amount of hitches that can be tied.
