The railing attachment is very poorly designed. The railing attachment for the worley bird is not strong enough to hold the the worly- bird upright when the wind is blowing. The threads on the railing attachment strip off when tightening it down enough to hold the worly-bird upright. As well, the railing attachment will not fit on an oblong boat rail. I suggest you redesign the railing attachment. The two I bought from you are unusable.
