  • These kits supply an external relay and installation instructions for driving existing OEM lockout valves on your crane when retro-fitting the L25 Radio Anti-Two-Block System. These kits, when properly installed, will insure that the L25 actuates your lockouts independently of any existing load system and will not interfere with their operation.  
  • These kits include some of the basic items we want on hand when installing one of these valves. The kits include 10 feet of oil resistant, flexible SO cable, crimp terminals, cable ties and the installation instructions. (We typically supply one kit per valve, so if you need purchase 3 valves, you would also get 30' of cable and sufficient terminals, ties etc. for 3 valves)
