The AS3301C vibratory screed features electrically heated screed plates and hydraulically driven rear-mounted extenders with heavy-duty support tubes that stabilize the extenders and provide rigidity for even material flow when paving wide widths. This screed performs well on interstates, airports and other high production applications. The AS3301C has a standard extendable paving range of 10 ft to 19 ft 6 in. and width of 24 ft 2 in.
