- Square-to-square inlet transition with a tapering, diamond-shaped interior. Transition is constructed from 400 Brinell Hardness Number (BHN) abrasion-resistant steel.
- V-notched blade constructed from 400 BHN abrasion-resistant steel.
The abrasion-resistant steel addresses the abrasive properties of sand. The diamond-shaped inlet transition and the V-notched blade work in tandem to provide precise metering of each sand color, so that subsequent production runs will create matching shingles of the same color.
