storage tanks are available in six sizes (10 lb., 20 lb., 30 lb., 50 lb.,
125 lb. and 250 lb.).
Mounting Bracket (10, 20, 30, 50) – Tank mounting bracket consists of
a rugged, welded steel back plate and clamp arm assembly. The bracket
is designed to retain and protect the agent storage tank in the normal
hostile environment that these systems are installed in. The bracket is
painted red enamel and can be mounted by bolting or welding.
