The Brunson 1.5THEDN is a cost-effective, temporary magnetic adapter for use with 1.5" diameter SMRs. Featuring a flat back and no anodized finish, it's ideal for budget-conscious applications that still demand flexibility and reliability. The magnet holds the SMR in place, while the adapter itself can be temporarily secured using adhesive (e.g., hot glue) to machine tools, concrete surfaces, pillars, stands, or other mounting locations.

Made from lightweight aluminum, it offers the same 1.125" (28.6 mm) center height as higher-end models, with a 1.6" diameter and 0.5" height. A practical choice for portable or short-term laser tracker setups.
