The BOLT® 3 boasts our Quad Agitation System: an industry leading design composed of three rotating agitators and a patented spiked auger. These combine to thoroughly open compressed loose fill, eliminating clumps and best conditioning fiberglass, cellulose, stone wool, and fireproofing materials for proper installation. Effective coverage in attics, walls, and cavities is easy, thanks to its 100 FT hose.
