This bracket is designed to be used during the new-construction (or pre-construction) phase of a build to rough-in the location of your speakers. There are several features that make this ideal for your in-wall or in-ceiling speaker project. The arms (or wings) are translucent and have center markings which allow you to make visual adjustments to the stud, up to 90° . The bracket can either be screwed or stapled into place, and for easy reference.
