I [i]think[/i] the Warwick style (2-piece) units will do the same.
I've got a Kahler (2400?) on my Vigier. It's a royal bugger to do the intonation, and as Ped will tell you, the action adjustment is adjusted in half-turn increments of the saddles. That was too coarse an adjustment for him, but I found it fine. Beyond that, they're excellent but pricey!
I really don't know how tight the Kahlers will go, but I'd guess at 15mm or even tighter, due to the shape of the rail pieces.[/quote]
It was a Kahler I used the last time I did one of these so I know exactly how horrible they are to adjust and tighten up without them falling apart in your hands.
Aha, found one and not as expensive as I thought it would be

Just contacted the seller to double check that it will go down to 15mm but should as it looks to be the same model I used the last time
