<p>An adjustable setsquare for a power tool guide rail is described. The setsquare comprises attachment means 20, in the form of a bar, for locating into a channel on the guide rail. The cross section of the attachment means is generally V-shaped and arranged such that the setsquare can be removed and reattached to the guide rail with consistency, whereby the angular displacement between a reference surface 18 of the setsquare and the intended line of cut to be made by a power tool disposed on the guide rail remains constant after each reattachment of the setsquare.</p> |
