So you're going on a little getaway, and you don't want any zip line parties at your house while you're gone?  Perfect!  This little lock is invaluable.  Use this lock to secure the trolley to the top of your zip line by threading it through a carabiner slot and around your anchor or terminating hardware. 

Note:  COLOR & STYLE MAY VARY Designed for trolleys that are made to stay semi-permanently on the zip line cable. Trolleys that disconnect easily can simply be detached and stored indoors.
