These carriers can be used on any 4 1/2”
system where end openers are needed or
desired. The Economy carrier offers the
same type of function as the Deluxe. The
basic unit is black while the Mosler unit
is white. The Mosler unit requires a white
end cap in order to function properly
in the Autobanker. The Economy carrier
is less expensive because it uses a velcro
band and single air disc as the air seal.
