Multiquip FS21 21-Foot Flexible Concrete Vibrator Shaft High-Carbon Steel Core Quick Disconnect for CV Series Motors & 1400-2600HD Heads

Maximum Reach for Deep Column and Wall Consolidation

Tackle the deepest pours and most challenging job site geometries with the Multiquip FS21 Flexible Shaft. At an impressive 21 feet (6.4 meters) in length, this shaft provides the extended reach necessary for vibrating tall columns, deep wall forms, and extensive footings without moving your power unit. Engineered for professional durability, the inner core is wound from high-carbon spring wire, specifically designed to resist unraveling and stretching under the heavy torque loads of concrete consolidation.

Built to survive harsh construction environments, the FS21 features the industry's strongest outer casing—a rugged composite of flat steel wire reinforcement, steel wire mesh, and a tough, abrasion-resistant rubber jacket. This multi-layer design protects the rotating core from kinking and crushing damage. The integrated quick-disconnect coupler ensures fast, tool-free attachment to Multiquip CV2 and CV3 electric motors or G55H gasoline drive units. Whether you are driving a compact 1400HD head or a massive 2600HD steel head, this shaft delivers reliable power transfer to ensure structural integrity and a smooth finish.

Specifications

Pro-Tip: Due to the 21-foot length, it is critical to avoid tight bends during operation. Keep the shaft as straight as possible to minimize internal friction and heat buildup. When storing, coil the shaft loosely (avoiding kinks) to prolong the life of the inner core and outer casing.
