I am trying to join PC-1 SRAM chain, it has such snaplock:

enter image description here

And the problem is, the distance between holes is slightly less (IMHO) than distance between the pins. Every hole on its own fits any pin, but so far I am unable to put the golden part onto the pins, either one holes fit, or the other -- and I cannot make them both snap at the same time.

I have manual for this chain, but irony, it describes how to use silver power lock (asymmetric), not this one.

So, how to mount it? Should I use tools like pliers?

I run a Rohloff on my bike and this is the first time using this kind of chain... THANK YOU FOR THIS INSTALLATION TIP!!! I was going nuts :) – user11129 May 2 '14 at 3:40

Put link into chain, hold chain on either side, use thumbs to hold snaplock over link. Gently pull chain using thumbs as fulcrums...this will put pressure on the pins forcing them just a tiny bit inward. Snaplock should slide over. (Think of it kind of like bending but not breaking a pencil...both hands on pencil (chain), thumbs next to each other, gentle pressure.

Oh boy! And btw. for second time with chain, I missed the rigid axis of the chain, and initially I tried to rather squeeze it :-( Anyway, it worked, thank you very, very, much! – greenoldman Dec 12 '12 at 19:56
@greenoldman Confused the heck out of me first time too! – PeteH Dec 12 '12 at 21:57
I am having absolutely no luck installing the snap lock. My hands are now killing me and I'm no closer. Is there any other way? – user19829 Jun 5 '15 at 23:21
It worked.. Easy peasy... Thanks – Manuchao Jan 4 at 20:03
