![Heavy Duty Zip Line Brake Block - Zip Line Stop](http://www.ziplinestop.com/cdn/shop/products/heavy-duty-zip-line-brake-block-parts-accessories-7130946994238_{width}x.jpg?v=1563154163)
The Stop Block can be used to create a no-pass point on any zip line cable, such as dropping over a body of water, prohibiting riders from reaching the end of the cable or it can be used as an emergency backup to a brake system. The Stop Block is not intended for use as a stand alone primary brake; riders should have little to no momentum upon impact with the Stop Block. Choose the cable size. The Stop Block is not a braking system.
