Currently there are three frame lines and 7 frame mouldings available. The Monolith Line is a series of simple flat frames (The HAL-1000, HAL-2000, and HAL-3000). The Autofac Line (Autofac 001 and Autofac 002) are frames cut with a 45 degree bevel. Based off of a Japanese frame, these are meant to be simple, but still have a little more character than the HAL or Multivac Line. My most popular set of frames is the Multivac Line (Multivac One, Multivac Two, Multivac Three). They are cut at a 22.5 degree bevel and add something extra to a piece, but do not take extra attention away from it.
