What size brick do the hangers fit?
A Both hanger designs are made to fit a standard Australian brick of approximately 75 mms or approximately 3 inches. However the designs allow for a small variation in brick size of approximately 2 mms,( 1/8 of an inch) larger or smaller, (a total adjustment of approximately 4mms or 1/4 of an inch). If your bricks fall within these margins then Brick Grips hangers should work for you.
