Indonesian Made On-Demand Posi Locker
Some creative young Indonesians have designed and made a cable operated on-demand positive locking differential. Until recently, 4-wheelers in Indonesia still mostly purchase posi lockers from overseas, commonly from the US.
This Indonesian made posi locker provides 100% differential locking when operated. I haven't seen the stuff, but I think it is almost similar in principle with the US made Ox Lockers.
