341A2M A favorite among municipal and utility crews for compacting around both utility line repairs and new installations such as street lights, fire hydrants, and telephone poles prior to pouring concrete. 441A2 This unit features all of the same rugged design features as the 35 lb model, but adds extra weight and power to extend deep into the soils and substructures for those applications where deeper backfill is necessary. 130A1M Ideal for compacting sand molds in a foundry or casting facility, the short size, light weight and long throttle lever allow this unit to be used on smaller models that are set up waist high. 241A1M This unit features a long handle, heavier stroke, two times the weight, and double the BPM of the 130A1M. This unit is easily held from a standing position while compacting very large molds at floor level.
