I have Googled for this, looked on Burley's site, and searched these forums and I haven't been able to find any sign that anyone else has this issue. So I'm asking it here and hoping someone has encountered this or has some advice.
Basically, the flag on my Burley Encore trailer (bought new in 2012) gets pulled out of its socket just a bit after riding for a few minutes. Then it falls over about 45 degrees while staying in the holder. So far it hasn't gotten yanked all the way out, but I do worry about that happening someday. I have tried pushing it into the socket as hard as I can and it's certainly difficult to pull it back out. But it seems the wind on the flag or possibly bumps in the road are enough to dislodge it after just a little riding.
As far as I can tell, there is no securing mechanism; the flag pole is just supposed to be stuck in the socket and stay in place with friction. I've thought about using a screw or something to keep it in place, but I'm not sure how to do that without ruining the flag pole or the socket. I've also thought about wrapping the pole with some tape or something, but haven't tried that yet.
Anyone seen this before, and/or have any ideas for how to fix?
