If you're asking about the slide-locks, then there was a recent thread with some good answers:

I'll reiterate mine here:
I don't use them for the short distance between the storage lot and home, but even at that short distance I've noticed a gap at the top of the slide by about 1" so I use them whenever I'm running on the highway.
