Hope it works out for you.
BTW, I'd suggest putting thread lock on the screw clamp. First time I fitted it, it popped off (helpfully in the middle of a junction of course

)
To be honest I think it was probably more to do with me not having tightened it properly, because where I was fitting it was completely inaccessible with tools, but just in case...
nb: it's been on there for 3 years since with no problems.
