I was a little surprised that only 3 mounting tabs are available here, which is represented differently in the pictures. The claws (unevenness) on the ground burrow into the wood panel, making it the vise without it wobbles and move can be to fix. Why the 4 mounting missing is incomprehensible for me, but I was answered by Berlan that it is so. Whoever opens the vise too far run the risk that the product may fall a part of the vice - I hope that then neither foot is still underneath the floor is massively damaged. This field safety notice was dismissed by Berlan as non-critical. A fuse on the spindle-end would have been a simple solution. Who does not want to have protruding outward the two clamps of the rotation, to solve before fixing on the workbench the lower nut to such an extent that they will be implemented by a 1/4 turn, so is in the tensioned state no projection of the tensioner gone. Please check before tightening on the workbench. Otherwise this is a good deal.
