Size of CO2 Tank

[ascha]

I'm picking up some wood today to build a collar for my keezer and I want to make sure I have enough clearance for the CO2 tank. Does anybody know how tall a 5lb tank with a Taprite dual regulator is?

Mine aluminum and steel cylinders with regulators connected are 19" +- 1/2".

Mines not a tapright, but it's 18 3/4", there shouldn't be a big difference between regulators.
