An extension table is for use with a table saw which includes a table with discharge end and power saw. The extension table includes a base, a cylinder and a support assembly which supports the base. The base is a rectangular member which has a bottom surface with a rectangular slot on the bottom surface thereof and two arms. The cylinder is rotatingly coupled to the two arms by two screws. The support assembly has a support beam, a slidable support and an adjustable coupler. The support beam has a first elongated slot. The slidable support is an inverted Y-shaped member having a leg which is insertedly coupled into the rectangular slot of the base and two arms which are slidably coupled to the support beam. The adjustable coupler includes a coupling beam which has a second elongated slot, two chains and a board. The coupling beam is mechanically coupled to the table at its discharge end adjacent to the bottom thereof. Each chain is detachably coupled to the table at its discharge end adjacent to the top thereof and is mechanically coupled to the support beam. The board has two ends each of which is disposed in one of the first and second elongated slots of the support beam and the coupling beam, respectively. The extension table is attached to the table saw in order to facilitate support of a comparatively long board throughout its entire length of travel.
