Yeah what vudu commented might be the issue causing the screw to be too long and touching the tube. One quick solution, try to see if by any chance you dropped one of the spacers that sit between the knob and the frame. Solution 2: file down the screw of the knob. Otherwise, get in touch with us like Kayleigh said and will send you a Screw and spacer replacement right away.

The Direkt vise has been revise to clamp both steel and plastic tubes as long as they are up to 8mm in diameter.
