Abstract: A light module projects multiple light beams onto an installation surface to form multiple light indicia spaced apart in a pattern on the installation surface, with the light indicia identifying installation locations on the installation surface where construction mounts are then installed. Embodiments include systems in which the light module includes a light emitter that projects a source light beam and a diffractor that diffuses the source light beam into the multiple light beams, systems in which the light module is adjustably mounted to and movable with a handheld tool used to install the construction mounts, systems in which the light module is adjustably mounted to a static-use support, and methods of using these systems to install the construction mounts.

Abstract: Refractory anchoring devices include a main body and a mounting feature for mounting to a thermal vessel. The main body includes four anchor branch segments angled with respect to each other to form an X shape with four unenclosed cell openings, including two opposite triangular side openings and two opposite triangular end openings. In some embodiments, the main body further includes extension segments extending from and angled relative to respective branch segments to define two of the opposite openings as semi-hexagonal. Some embodiments include reinforcement segments extending from branch segments into openings, voids extending through branch segments, two anchor strips inter-engaged to form the four branch segments, and/or a single stud-welding stud for the mounting feature.
