查看詳細說明Needed a replacement for the left side and this one lined up perfectly with the frame threads, no wobble once I tightened it down. Saved me from buying a whole new setup.
Took a while to find the exact left-side replacement, so I'm glad this one matches the original perfectly. The threading is smooth and it locks into place without any wobble, feels just as solid as day one.
Replacing the old worn-out screw was painless since this one fits the frame exactly like the original. The threading is precise and it tightened up without any wobble, so I’m back to using the system daily. Glad I could get just the left part instead of buying a whole new setup.
