A relatively thin, stiff, flat guide line holder or “trig” for accurately supporting and positioning intermediate portions of tautly stretched guide lines such as are used by bricklayers and stone masons in laying courses of bricks, blocks and stones during the erection of masonry walls has a centrally located body portion, and an integrally formed, forwardly projecting guide line support portion. During use, the body portion is positioned atop a flat surface of a wall being erected to support the line holder at a desired height to be met by masonry elements added to the wall, with the support portion projecting forwardly beyond a front surface plane of the wall being erected. Passage formations defined by the support portion open downwardly through a bottom surface of the support portion at two spaced locations along the front surface plane when the line holder is properly positioned. Slot formations defined by the support portion provide a track, or tracks, along which a loop of the guide line can be moved into the passage formations so lengthy portions of the guide line located on opposite sides of the loop can extend along the front surface plane in opposite directions away from the line holder when the guide line is drawn taut at the desired height.

The line holder of claim 8 wherein the elongate strip has a substantially rectangular shape. 11. A line holder comprising a one-piece stiff, flat, elongate strip having one end and an opposite end defined by the elongate shape of the strip, having two side-by-side passages extending through the strip at locations spaced substantially equidistantly from an end surface at the one end of the strip, wherein the passages each communicate with a different one of two slots extending through a thickness of the strip and in a lengthwise direction relative to the elongate shape of the strip to open through the end surface, wherein the passages are transversely wider relative to the lengthwise direction than are portions of the slots located adjacent to and communicating with the passages. 12. The line holder of claim 11 additionally including a single passage extending through the strip at a location spaced from an opposite end surface at the opposite end of the strip and communicating with a third slot extending through the thickness of the strip and in the lengthwise direction to open through the opposite end surface of the strip. 13. A line holder for supporting and positioning an intermediate reach of a mason's guide line when drawn taut to extend away from the line holder in opposite directions along a linear path at a desired height adjacent a front surface plane of a wall being built, comprising a thin, stiff, elongate member having a centrally located body portion positionable atop a horizontal surface of the wall at the desired height, and having a guide line support portion formed integrally with and projecting forwardly from the body portion 1) to define passage means opening downwardly through a bottom surface of the support portion at two locations along the linear path within the front surface plane, and 2) to define slot means communicating with the passage means to provide a track along which a loop of the reach can be moved into the passage means to depend through the bottom surface at said locations; wherein: the passage means defines two bottom surface openings at said locations, both of which openings are elongate in directions extending along said path;the passage means includes two elongate passages each communicating with a different one of the two elongate bottom surface openings;the slot means includes a single C-shaped slot communicating at one end with one of the elongate passages, and at the other end with the other of the elongate passages; andthe one end opens into the one elongate passage midway along the length of the one elongate passage, and the opposite end opens into the other elongate passage midway along the length of the other elongate passage. 14.
