1/2″ x 10′ V-Flip Wire-Core Flipline With A Swivel Double Locking Steel Snap. The V-Flip Flipline is constructed with a 12-strand coated polyester outer jacket over a cut resistant wire-core. A forged steel climb rated swivel snap is connected via a swaged eye termination and the tail end is terminated with a thimbled eye to prevent pull through. Swivel snaps are recomended when mechanical rope grabs will be used for length adjustment.
