Looms with fixed beams cannot be converted to removable beams.
How to Install
If necessary, remove the old back beam.
Slide the new back beam into the slots cut in the top of the inside legs.
Insert a 1/4-20 barrel nut into the hole on one end of the back beam. Place a 1/4" fender washer on a back beam knob and insert the knob through the inside leg into the back beam. Tighten the knob into the barrel nut.
