| 1. A setsquare for use in conjunction with a power tool guide rail, comprising:
a body comprising an arm having a vertical surface arranged to depend downwardly from an underside surface of a guide rail
when the setsquare is in use and/or disposed on a guide rail, the vertical surface being arranged for abutting an edge of
a work-piece;
an attachment member arranged to attach the setsquare to a portion of a guide rail, such that the vertical surface is in a
predetermined alignment with respect to an edge of the guide rail; and
a locking member moveable between a locked and unlocked position such that the setsquare is removable from a guide rail when
the locking member is in the unlocked position,
wherein the attachment member comprises a linear component having a cross section arranged such that, when the setsquare is
removed and re-disposed on a guide rail and the locking member is in the locked position, the alignment of the vertical edge
with respect to an edge of the guide rail remains unchanged.
