The CADAC dual control extension arm is one of the accessories that should not be left at home when going on a camping trip. It is used to enable two appliances to operate off one cylinder simultaneously. When you are living outdoors you may want to use two appliances at once, but require the functionality of having control over the heat for each appliance. This is when you will need the dual control ability of this unique unit. It extends far enough from cylinder to make cooking possible on two appliances. Save time and also gas by not having to wait for one dish to be prepared and then putting on the next dish. You can also run a lamp and a cooking appliance together making it possible to have light in the camp and to cook at the same time from one cylinder.
