Renae's Red-E-Edge Snapper Clamps 16"

Make sure that when you choose the size you allow some wiggle room to move the longarm over the edge to change the bobbin. The best size would be about 4-5" less than the throat of your longarm. EXAMPLE: 26" throat works best with a 19" Red-E-Edge. 16" throat works best with a 12" Red E Edge.
