<p>A four sided template for use in cutting tiles, comprises two opposed pairs of linear straight edged arms 1a, 1b, 1c and 1d, which form a four sided figure. Each arm is formed with a longitudinally extending slot 3 of uniform width along the major part of its length. Four connectors 7 are provided, each having an internally threaded cap (9, fig 2) connectable to an externally threaded portion of a spindle (17, fig 2) of a base (11, fig 2), where the diameter of at least three of the spindles is marginally less than the width of its respective slot. The superimposed arms can selectively be locked together by tightening the respective cap on its spindle or, by loosening the cap, the angle created by the arms can be changed and the position of one arm relative to the other can be varied. The length of the arms of one pair of arms is the same, or substantially the same, and the length of the arms of the other pair is also the same, or substantially the same. The template may have only four sides, and the four arms may be of equal length, or opposing pairs of arms may be of different lengths.</p> |
