Area of application

The variable Spannfix base parts allow precise and secure positioning in all directions. From sensors, gauges, monitors and surveillance cameras. The ESD versions have a dissipative black surface with a resistance between 10^7 and 10^8 ohm.
The SPANNFIX is a universal ball-joint-clamping-device. A third hand as a meaningfully clamp-and-hold-devices with a quick-clamp mechanism, a useful help in every workshop.


Technical description

EPA suitable. For working in electrostatically protected areas (ESD workplace / ESD protection zone). The ESD versions have a dissipative black surface with a resistance between 10^7 and 10^8 ohm. The base can be connected to the earthing point with a 10 mm push button.
Connection recommendation: 9-359-1 ESD earthing module 3x10 mm push button for table screw connection or 9-359-2 ESD earthing plug 2x10 mm push button and M5 connection for EU sockets. (Cable: 9-343-1 ESD earthing cable 1 MOhm, length 1.8 m)
Max. Torque or action on the joint head, ball force: ball Ø 40 mm = 160 N / 17 kg / ball Ø 60 mm = 450 N / 47 kg Please note that we cannot guarantee the holding force for safety-relevant parts without knowing your specific application. Under various physical conditions the ball can behave differently. Than in our test laboratory with an optimal test environment


General information

The SPANNFIX is a multifunctional vice with a flexible head and many possible applications. By using a high-quality ball joint, the head of the SPANNFIX can be tilted and fixed in any direction and offers optimum hold in any position. With the help of an adjusting screw at the lower seat of the ball, the ball mobility can be individually adjusted. The ball is held and released with a simple lever movement. Long service life is guaranteed by the high-quality, the powder-coated cast aluminium and the surface-finished steel parts!
