Non-breakable, trapezoidal tool is the newest to join Allied Construction Products LLC's full product line. No greasing required, and the tool has no tie-rods, tie-bolts or side-bolts. It has one bushing made of composite wear-resistant material instead of usual steel tool bushings. The compact design helps tool work in narrow areas. Available in four models—the Model 8, Model 11, Model 15 and Model 22. The working weight ranges from 152 pounds to 453 pounds with operating pressures from 2,030 psi to 2,175 psi.
