Flexible installation

FATH Friction Joints can be attached to the profile lengthwise, crosswise or on the front. The sets already contain the installation material for lateral attachment with T-slot nuts in profile slot 8 or 10 as well as for front attachment on a profile piece with an M8 core hole. To reduce a ø 10.2 mm core hole to thread size M8, you can use a FATH Cutting Bush with Shank 09308801. 

For installation on flat surfaces, the supplied slot fixing plates are simply omitted.

Optional M8 connection adapter

This stable connection to profiles with slot 8 or slot 10 is ideally suited for the construction of customized solutions. The M8 connection adapter can be attached to the profile both longitudinally and on the front. When using the centering piece, the central M8 screw connection can be secured against twisting. A friction joint half and an assembly set suitable for the profile size are required to install the M8 connection adapter at the end of your system arm.


Available in 7 different versions: with a fixed friction torque of 0.5 Nm, 3 Nm, 6 Nm, 9 Nm, 12 Nm or 15 Nm and with freely adjustable friction torque from light to strong.
