Product review (5 stars): Heavy Duty Hardware - Great Quality!
Installation was easy and the quality is amazing.  Very heavy top-quality hardware and connections.

A few tips:

1. Most CO2 refill companies will require you exchange your tank for theirs - be prepared to give up the nice aluminum tank.  Check your local fire extinguisher refill companies in the yellow pages and DO NOT use paintball refill retail outlets (some add lubricating oil to their CO2).

2.  If running the tower mounted on a bar outside of the refrigerator, you will need to keep the beer line temperature at a cool 38 degrees.  Do this by running the line through 2" PVC and using a 12 CPM pole fan (and 1" tube) inside the fridge to circulate the cool air through the pipe and tower.  I used a 2.5" hole saw to accommodate the piping.  Failure to do so will result in lukewarm foamy beer.

Enjoy!
