Description
Northrock PRO 1.5+ Electric Concrete Vibrator Motor — 1.5 HP, 115V, 13 Amp
The Northrock PRO 1.5+ (model 25L1, or 25L1QD with quick-disconnect) is a 1.5 HP single-phase electric power unit built for slabs, footings, columns, and light-to-medium residential and commercial pours. It drives Northrock flexible shafts and vibrator heads up to 1-1/2" diameter, delivering the mid-frequency vibration profile Northrock designs specifically to consolidate homogenous concrete mixes without destroying the freeze-thaw pressure-relief chains that higher-frequency competitive units can damage.
Like every Northrock electric vibrator, the PRO 1.5+ is designed and manufactured in Bohemia, New York, and is UL / cUL Listed.
Why contractors choose the PRO 1.5+
- High-strength cast aluminum housing — acts as a heat sink to dissipate motor heat on long pours, unlike the plastic shells used by many competitors.
- Shock-absorbing outer frame — protects the housing from jobsite drops and doubles as an ergonomic carry handle.
- Watertight, strain-relief power cord — prevents accidental cord pull-outs and resists water intrusion in wet-site conditions.
- Protected rocker switch with water-resistant seal — shielded inside the frame.
- Field-serviceable — brushes, switch, bearings, armature, and field are all accessible OEM-replaceable items. DanseUSA stocks the full 25L1 parts breakdown.
- Universal countershaft — order with adapters to drive existing Wacker, Wyco, Stow, Oztec, Mikasa, Multiquip (Mikasa PMA), Stone, Dynapac, Viber, Master, Denver, Dreyer, or Remington shafts and heads.
- Quick-disconnect option (25L1QD) — swap shafts in seconds on rental fleets or multi-trade jobsites.

Best applications
Footings, slabs-on-grade, driveways, sidewalks, curb-and-gutter, small columns and walls, residential foundations, and any pour where a 3/4", 1", 1-1/4", or 1-1/2" head provides the right radius of influence. For heavy wall and precast work, step up to the PRO 2+ or PRO 3+.
What's in the box
