The sectional beam designed for the Baby Wolf is a set of 4 rakes that are screwed into your existing warp beam. The wooden pegs are spaced at 2" on center. Adding these rakes gives your beam a 12" circumference. When the Baby Wolf with a sectional beam is folded, the depth is 20". Once the sectional beam is installed on the 8 harness Baby Wolf, the loom cannot be folded up completely.
