Area of application

The 50 mm protective jaws consist of a smooth plastic covering with pressure lock and are able to use to our ball joint vise 9-205-K. The smooth surface provides protected hold and good fixation of the parts and components to be machined. This snap fastener is a kind of Velcro tape with a very stable and precise fixation. By simply pressing them together - with small mushroom heads interlocking - a very firm, but removeable connection is created. The pressure fastener can be clicked crossed, offset or overlapped. It provides a permanent mechanical fastening that will not loosen even with sustained jarring motion. In contrast to a common Velcro fastener, this quickly releasable connection is characterized by high shear strength. The self-adhesive back immediately adheres with excellent final adhesive strength, even at high temperatures and on rough surfaces.

General information

Product fits to our SPANNFIX the 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.
