Abstract: A carpenter's level holding device and method for plumbing a wall partition is disclosed, characterized by use of a bracket to hold a conventional carpenter's level to removably attach and self-register the level on a wall partition and a method providing for the positioning, plumbing, and securing of a wall partition by a single user. The bracket includes a first portion adapted to mount one end of the level and a second portion formed to be selectively rested upon the top of a wall partition to thereby hold the carpenter's level securely against and parallel to the vertical timbers of the wall partition with the bracket maintaining the carpenter's level in position upon the wall partition, an individual user has both hands free to properly plumb and temporarily secure the wall partition in place.
