The urethane construction absorbs shock from impack and allows the broom to flex slightly, lessening fatigue and extending the life of the block. The handle is firmly attached to the block without threads for extra strength and to prevent handle wear. The fill material is is medium brown styrene, which offers high resistance to most common solvents such as gasoline, kerosene, etc. Note: Floor broom handles are sold separately.
