The ESD ball joint base SPANNFIX for screwing on (threaded pin 20 mm) is a dissipative, 360° rotatable ball-joint quick-release holder designed to secure heavy components and enable precise alignment in electrostatically protected areas (EPA). It provides stepless locking and is suitable for connection to workbenches, tables or adapter mounts.
Features- Ball-joint quick release for heavy parts, 360° rotation, stepless locking; quality product Made in Germany
- Screw-on base plate (footprint 150 × 106 mm) with four through-holes Ø 9 mm
- Threaded pin M12 × 1.5, pin length 20 mm; support surface approx. Ø 20 mm
- Inclination angle ±45°; movement adjustable via screw at the ball seat
- Cast aluminium with black ESD powder coating; dissipative resistance 10^7–10^8 Ω (EPA suitable)
- Dimensions approx. 90 × 180 × 110 mm; weight approx. 800 g
Area of applicationBall-joint holders are available with different ball diameters and corresponding holding forces. Minimal lever pressure enables stepless locking with high holding capacity. Typical uses include quick clamping and precise alignment of cameras, monitors, sensors and measuring instruments; fixtures in instrument and model making; carving plates in woodworking; and repair work on e-scooters, e-bikes and bicycles. The vice fastening fits table thicknesses up to 80 mm; the screw-on base is fastened via four Ø 9 mm through-holes. High-performance magnets are available for quick-change individual fastening.
