Question Mortise key cylinder questions??

I have a mortise door lock that takes a Shlage keyed cylinder.
I replaced it with a US Lock cylinder which was about 1/8" shorter than
the old cylinder I removed from the mortise lock assembly. I was able
to get the new cylinder into the threads on the mortise lock but only
about a half a turn.
Are mortise cylinders standardised in their length and thread width
sizes, or do they come in several lengths?
Will a medeco mortise cylinder also be fit in the mortise lock?
Thanks for your help!

Hi mouln,

To answer your question, mortise locks do come in verious lengths: 7/8"; 1"; 1 1/8"; 1 1/4"; and I've seen them up to 2". As far as the threading, it is standard, so a medeco will fit in your lock body.
