Magswitch Featherboards use an ingenious rare earth magnetic device to
tenaciously attach themselves to any cast iron or steel machine surface. In
the off position, the polarity of two stacked magnets oppose each other allowing the device to be moved to any position. Rotate the switch to the
on position, and the magnets align and activate to stick themselves to your
tabletop.
The Magswitch Pro Fence Featherboard will attach to a steel/iron
fence at least 3-1/2" tall for 3/4" stock and acts as a vertical hold down. 1" thick x 9" long and 2-3/4" wide.
