Abstract
A plumb guide for facilitating the laying of end bricks or other masonry units of a tier successively in true vertical alignment without the use of spirit levels and the like. The guide is adapted to be removably attached at selectable points on the usual bricklayer's gage line. A flat surface of the guide is disposed perpendicularly to the gage line, serving as a reference for the placement of end units in successive layers about windows, fireplaces and the like.
