I know that Spector uses a similar locking mechanism for its bridges.
Well, the Spector bridge (at least on my Euro 5XL) had bridge saddles that just kind of sat/floated on the platform base of the bridge and then could be locked in place once you'd manually slid them around to get the intonation set. There weren't the screws and springs whereby you could move the saddles forward and back using a Philips head screwdriver. I did not like that Spector version—although I did like the bass otherwise. [Edit: Just did a Google search and I see that at least some of the Spector bass bridges have the screw/spring set-up.]
