Our Stabilizer Bars  provide additional rigidity  for our Circle and Ellipse Jigs. They also provide  insurance against the router's vibration loosening any of the Micro Fence locking thumbscrews. Machined from aluminum bar stock, they clamp across all four rods of the Circle Jig and lock down with manual wing bolts.

We highly recommend the use of the Stabilizer Bar with every Circle or Ellipse Jig set-up and when cutting larger radii at 24' to 30" intervals (also see our Stabilizer Bar Levelers).
