604 crate what do you recommend non slip collar or slip collar ?

I'd save the money and get a non slip collar version. If it's end up needing adjusting then you can always shim to fit but I believe the 604 crate is on spec as I know lots of guys using the non slip collar without issues.

You can always cut the collar off and buy the slip ring down the road if you end up with a motor it wont fit
