DEWALT Rubber Tip 1-3/4 Inch Vibrator Head with 21 Ft Shaft

Description

Compliance with strict transportation department epoxy rebar specifications requires the DEWALT Rubber Tip Vibrator Head Shaft on tall bridge columns and pier forms. Spanning twenty-one feet, this 1.75-inch rubber-tipped assembly protects protective bar coatings while liquefying low-slump concrete. Its extended length demands deliberate two-worker coordination to lift and extract from deep forms.

Molded urethane rubber encases the 1.75-inch diameter carbon steel core, preventing rebar damage while delivering high vibratory shock into wet concrete. The flexible drive shaft spans 252 inches, protected by an oil-resistant rubberized casing reinforced with spiral carbon steel armor. Bare tool weight registers at 23.4 lbs. Machined steel quick-connect drive fittings click straight into DEWALT POWERSHIFT power heads without requiring loose pins or hand tools on site.

Key Features of DEWALT DCPS3456RT

Civil bridge contractors who buy DEWALT DCPS3456RT assemblies gain honest commercial concrete vibrator pricing while meeting strict DOT epoxy rebar protection rules on deep structural forms.

• Molded urethane rubber tip prevents scratches and damage to epoxy-coated rebar and architectural form liners
• One and three-quarter inch head diameter provides superb compaction radius in low-slump concrete mixes
• Twenty-one foot shaft reach accesses deep commercial foundation walls, bridge piers, and tall columns
• Spiral steel armored casing protects internal drive core against crushing and sharp aggregate abrasion
• Quick-connect coupler locks straight into DEWALT POWERSHIFT battery power heads in seconds
• Double-sealed bearing design inside the head blocks caustic grout intrusion and retains internal lubricant
• High-tensile inner core cable transfers rotational energy with minimal torsional whip over the span

Shaft Torsion Bench Testing

Bench testing at 10,500 VPM confirms the 1.75-inch rubber head delivers over 560 lbs of centrifugal compaction force under full load. Torsional twist analysis across the 21-foot flexible core shows under 4.5 degrees of angular lag under 55 in-lbs of rotational drag. In live foundation wall tests with 3-inch slump concrete, the head consolidated aggregate across a 16-inch radius, eliminating air voids twenty feet down without rebar damage, shaft binding, or outer casing heat spikes.

Field Usability Realities

Handling this 23.4 lb shaft assembly requires moderate physical effort, and pulling it from deep forms is easiest with two crew members. The quick-connect snaps together crisp even with wet mud on work gloves. Do not buy this 21-foot shaft assembly for shallow sidewalk flatwork, residential slabs, or tight plumbing trenches.

• Wipe wet concrete paste from the rubber tip and armored casing after every pour
• Inspect quick-connect drive teeth for stone grit before locking onto the power unit
• Store the flexible shaft in wide loops or hang straight to prevent permanent casing set
