No, it has locks. It can be free both ways, only in, only out and no way, Jose!
Sounds like the one I ordered from Amazon yesterday. Since Kater is chipped it should work properly. I'll know in a couple of weeks after it gets here and I have installed it through a 5" thick wall. My house is coming along, the furniture is finally all glued together and looking good. still have to cut, sand, oil and mount a few hardwood shelves, and hang up around 50 trophys.
Today I'll get started installing my livingroom sound system running all the wiring for a 7.1 system through conduit. That should be fun since each of the CEN, LS, LR, RR, and RS locations will have 4 small bookshelf speakers mounted. LF and RF speakers are older Klipsch Heresys which sound good without being doubled or quadded.
The beginning of next week I'll check all my sensors in a pressure pot, analyse all my tanks and check my rebreathers. Hopefully I can then talk Pete into giving me a "Discover Local Diving" refresher course in one of the local sites since the last time I was diving was the beginning of March before I started packing for the move to Lake City.
