The largest of the disposable, Halon blend models, the RT A1200 is a popular alternative to the 2.5 lb. gauged extinguishers for those who put a premium on light weight and low maintenance vs. the desirability of a gauge and the ability to recharge after use.
The A1600 offers a superb firepower to weight ratio. Aluminum construction helps this model achieve a gross weight similar to many 2.5 lb models, despite the fact that it contains 40% more Halon 1211.
