2-in-1 Angle Measurer with Sliding Arm

This 2-in-1 measuring tool combines a semicircular angle measurer body with a straight sliding rule arm, eliminating the need to switch between instruments when transferring angles. Crafted from silver metal, it features deeply engraved degree markings on the rounded section for clear readability. The built-in locking hand knob and T-slot allow secure adjustment of the arm. The front end of the rule arm ensures the tool sits flat against materials, making it suitable for layout, drafting, and marking tasks in workshops and DIY garages.
