Our spacer frames are made from 1/4" steel and can support the weight of a hopper and loader,
so they can be mounted directly over the feed throat. Color is metered in by a removable nozzle.
Inside the frame, a canopy directs resin to either side the nozzle to help prevent color and resin clumping together.
The spacer /  nozzle option is a good solution in situations where a slide gate prevents us from metering
into the throat directly over the screw. By using a removable color nozzle,
this is also a good option if you frequently change from using color to running natural resin.
