Bergkamp Spreader Box

Variable-width spreader box (VSB) eases micro-surfacing where widths fluctuate. The box expands and contracts while paving. It has four augers; the first two feed the material to the center of the box while the other two evenly distribute the mix during placement. The VSB is available in 8- to 13-foot, 9- to 14-foot, and 10- to 15-foot models.
