Just received this rail fitting from one of the vendors, but the mounting "slots" barely reach the mounting holes in the rail ('90). I specifically ordered the 1G outlet fitting, is this not what I got or is the 1990 rail different

but Niu at ExtremePSI responded that this fitting was apparently designed to fit both 1G and 2G rails. Guess the 1G fitment wasn't tested 
I'm pretty sure the large one goes to the outlet and the smaller one goes to the inlet.
