Abstract
The invention relates generally to plumbing control joints in masonry walls, and apparatus for plumbing a control joint in a brick wall surface. A mounting bracket supports a bracket rod and cylindrical collar which may slide axially along and pivot about the bracket rod. The plumb rod is slidably received in an adjustable holding member. The plumb rod is then secured relative to the holding member. A spirit level is fixed within a circular bore of the holding member, which can be adjusted to the user's desired position. To ensure the plumb rod is perpendicular to level ground, the holding member is pivoted until the spirit level indicates the desired result and the position is secured. A plumb control joint is guaranteed by successively laying the brick layers against the plumb rod in a manner which is typically known in the art.
