Non-binding fence for a table saw

A guide assembly for a saw device includes a pre-load mechanism located at one end and a slide mechanism located at the other end. The slide mechanism establishes two fixed contact points between the guide assembly and a guide rail of the saw device. The pre-load mechanism establishes a third contact point between the guide assembly and another guide rail of the saw device. The guide assembly has an unlocked condition in which the pre-load mechanism continuously generates a first clamping force on the saw device between the third contact point and the two fixed contact points. The first clamping force self-aligns the guide assembly to the saw device and permits slidable adjustment of the guide assembly on the saw device. The guide assembly has a locked condition in which a second clamping force is generated between the contact points and the guide assembly is fixed on the saw device.
