Standard asphalt drum discharge flights tend to wear down prematurely, allowing asphalt to accumulate and clog the discharge area of the drum. Kenco Discharge Flights with a 1" x 1" tungsten carbide impregnated wear bar are designed to stay at full size for a much longer time. As a result they provide superior clean-out performance while minimizing asphalt buildup Additionally, the 1" x 1" wear bar provides an easy visual check of flight wear from the access hatch on many drums.
