Claim:
An adjustable fence for use with a table saw, wherein the table saw has a rotatable blade that extends through an aperture of a table top, the table top having indicia that provides a reference of parallelism to the plane of the blade, said fence having at least two recesses in the side and bottom thereof, each having an angled surface configured to have a rocker mechanism attached thereto, said fence comprising: a front clamping portion having a mechanism for securing said fence on the table saw; an elongated portion attached to said clamping portion and extending from the front to the back of the table top, said elongated portion being substantially parallel to the plane of the blade; at least two visual indicating devices positioned on at least one side of said fence at spaced locations along the length of said fence, said devices enabling an observer to compare the lateral position of the fence at each location relative to the indicia and determine if said elongated portion is substantially parallel to the indicia, said visual indicating devices comprise at least two light emitting laser LED units mounted on respective adjustable rocker mechanisms that are mounted on said fence at spaced locations along the length of said fence, each laser LED unit being configured to direct a narrow beam of light beam a predetermined distance from a first side of said fence toward the indicia and enable an observer to compare the location of each point relative to the indicia and determine if said elongated portion is substantially parallel to the indicia.
