Manfrotto Suporte 155

When I first got this, it didn't fit over the rubber foot for my 681B pod (the foot is too huge). I tried putting the spike on without the rubber foot and, though it fit, was heart attack inducing to tighten. Even after tightening I could still pull it off with little effort. So I messed around with the bearing on the screw and then the nut. I turned the nut around (so the text is facing outwards) and it became far easier to tighten. The tightening was then solid and took a lot more of me to pull off. So beware when buying this for a 681B, it works great now, but took some very lite tweaking.

I was originally going to buy a replacement rubber piece, but I couldn't find the one I needed. So I ended up ordering this spiked foot instead. Works really well and makes my monopod rotate smooth on the ground.

Bought this with my monopod and it serves its purpose very well
