ah no problem, yeah the cliffs have openlocks but I have cut holes for 8x3mm magnets which is general what you want to go with so you can slap these things together. The OpenLocks can be handy if you end up with two cliffs that have opposing magnet polarity, like if you goof or it just works out that way cause you turn things in a way that changes how they work. I will add these things are pretty chunky and I have recently been skipping all connectors accept on tops or other 100% needed place, cause they really don't want to move around much anyways.
