Main Unit Assembly 5170055-53

Restore the performance of your laser level with this main unit assembly, the core component that houses the primary operating and leveling systems of the tool. Replacing a damaged or malfunctioning main unit can help restore accuracy, reliability, and overall functionality without replacing the entire laser level. Designed as a direct replacement for the original assembly, it is an ideal solution for major repairs and rebuilding projects. Because this is a central internal assembly, refer to your model's parts diagram or service documentation to confirm the correct application and installation before repair. Sold individually.
