If you have an old kegerator or were planning on buying one, this is most likely the size of the tower that you would need. Check the dimensions. If it's 2 1/2", you're in business.
It's not hard to install at all. All you need is a screwdriver to tighten the tower. If you're planning on a different project, you'll need a drill, drill bits and plans. But, it's not hard to get it right. Installing a beer tower is not brain surgery.
You can dress up your tower to look and pour the way you want:
Bottom flange with 4 screw holes
Complete with faucet and 3/16" beer hose
2-1/2" Column Diameter
Weight: 5 lbs
