As a shortcoming, I consider that rod relatively easy to get out again rotates when you turn the patch Einspannhife, or moved to pull her up to change sides. I turn now only halt this principle clockwise. If I am nervous but even more I give assurance paint onto thread as it is anyway permanently mounted with me.
Conclusion: No matter what stand (Table 2 assembly variations or with clamp) a buy recommendation from me for a useful accessory.
