Manfrotto 546B 三腳架用撐開器連接組件 R546,12

Finally found the exact replacement part for my 546B after searching—this coupling assembly fit perfectly and feels just as sturdy as the original. The metal construction is reassuringly solid for a part that takes so much weight.

Replacing my old spreader connector felt like a gamble, but this assembly clicked right into the mid-level mount without any wobble. The metal feels sturdier than the plastic original, and it locks tight even on uneven ground.

The threads matched up perfectly and the coupling feels solidly machined, no wobble at all. My mid-level spreader is finally secure again, which saved me from buying a whole new tripod.
