This kit was put together to make your life easier. Compact enough to not get in the way but strong enough to get the job done. Combining the high-quality WestFall hardware and rope is a no brainer for strength and durability. The kit can provide 4:1 or 5:1 assistance depending on the configuration. Depending on how you rig the pulleys will determine the working length. The rope is 8mm and strong enough to get the job done.
