The 3490-025 Stainless Steel Base w/Outer Corners contains:
• Ball prism base for outer corners, for ball-Ø 1.5″ (38.1mm)
• Integrated permanent magnet (often available with two holding forces)
• Height-offset: 25mm
The base is placed on the corner/edge and the ball prism is aligned with the tachymeter for measurement. With magnetic surfaces, the integrated permanent magnet ensures that the base sticks automatically to the measuring object and does not have to be held by hand during the measurement. For measurements in the vertical or overhead position, we recommend the version with the strong magnet.
