This "Fast-Release" kit is the ideal complement for your Harken Micro 468 jammer. Quick release wire for microphone cleat - It quickly releases the stuck rope. The 494 and 495 quick release threads set up at the outlet of the tracker. They include stainless steel wire guides with low friction that keep the cleat away to avoid its accidental blockage during maneuvers. They are perfect for applications requiring rapid release of ropes, especially when it comes to collapsed the SPI when passing a buoy. Harken threads for taps are made of robust abrasion -resistant composite materials. Use the 495 model with CAM-MATIC® micro 468 and 471 TAUCTORS.
