I have a new RDM mast extension from Chinook. I can't for the life of me get the collar pins to seat into the aluminum. I've had a few Chinook extensions over the years and have never had this problem. In about 40 minutes of wrestling with it, I've managed to get it seated into the holes three times. Each time it worked it just sort of snapped into place - I don't know what I did differently. Once in the holes it's easy to snap out by pushing/twisting it with my thumb. This collar has 4 pins whereas my older SDM extension has only 2 pins.

Any clues on how to do this? It can't be this hard...

I have the aluminium one and yes it was difficult to snap in at first. No trouble now I just knead it from round the back toward the pin. Don't know if it because its worn in a bit or I just know the technique sub conciesly now great mast extension though

40 mins !!! It shouldn't be that hard, I'd be tossing it after 40 seconds. Could be faulty, I've had bad boom clips. Take it back for a replacement.

Maybe try spinning it 180 degrees and coming at it from the other side.
The holes might be slightly of centre

Yes now that I think about it that's what I had to do spin it 180 degrees, haven't had a problem since.
