UltraBrake Polymer Zip Line Brake Block

Made by CMI. Crafted from an ultra high strength polymer designed to outwear some metals, nylons, and urethane. Designed for hard use and maximum UV resistance, the material has a low friction coefficient and is self-lubricating with a non-adherent surface. It's black color blends in with forest surroundings and galvanized hardware prevents rust for a long lifetime. Available in two different sizes to accommodate a wide range of cables. Mounts around cable and attaches to a static point with a bungee cord (not included). This brake block is sold as a component to an integrated braking system. It is designed to be used as part of a gravity based brake system and be attached to a shock cord. It should never be used alone or without a backup emergency brake in the event of a failure. There are two eyebolts installed in this block. One should be rigged to take the impact from the rider. The second should be connected to the first with a slack tether.
