ABSTRACT:
A pair of brackets (B1, B2) are mounted on the outside corner of a brick wall, one above the other. Each bracket (B1, B2) includes a pair of arms (16, 18) and inwardly directed cleats (32, 34) on the arms (16, 18) which fit into vertical joints (J) between the bricks in a corner. The cleats (32, 34) are adjustable in position along the arms (16, 18). Adjustment bolts (50, 52) are rotated to move the cleats (32, 34) towards the arms (18, 16) to in that manner clamp the corner bricks (78, 80) between the cleats (32, 34) and the arms (18, 16). Each bracket (B1, B2) includes a pair of pole sockets (82, 84). A vertical string pole (10) is positioned within the pole sockets (82). A vertical string pole (12) is positioned within the vertical pole sockets (84). Set screws (94, 96, 98) and (100, 102, 104) are adjustable to plumb the string poles (10, 12) and secure them to the brackets (B1, B2). Strings (S) extend horizontally between string poles (12, 14) at opposite ends of the wall part (112). The string (S) is set to provide a guide to the bricklayer, for laying a new horizontal course of bricks onto the wall part (112).
