Available in 7.25", 9.5" and 12" radii, right-handed and left-handed variants.  

I currently have a quickie/not professional video that details a couple of the finer points to the bridge set up. PLEASE NOTE:  For 2022, I have made the switch to spring-loaded intonation screws and I now ship with the adjustable post collars rotated 180 degrees from where they are in this video.  The bridges are shipped "pre-intonated" but depending on the thimble location of your particular guitar and if and how you need to adjust your collars you may need to tweak just a bit.
