The 9904 Magnetic Pedestal Base gives you the convenience of a magnetic base with the same stability and low beam height of our pedestal risers. It is great in applications where tight space means you can't use a holding fork. The magnet is strong enough to maintain its position as you make adjustments, but allows you to do some fine positioning with a firm push. Once your mount is positioned, you can even use our holding forks to lock these pedestals in place.
