The CSV 35: Honda Reliability in a Handheld.

##### Grind Ceilings Without the Ladder.

The NorthRock PRO 1200 transforms the most fatigue-inducing job on the site—overhead grinding—into a safe, ground-level operation. Designed to remove form marks, seams, and imperfections from concrete ceilings, this unit eliminates the need for scaffolding or stilts. **For jobsites requiring silica dust compliance, the PRO 1200V model features an integrated vacuum guard system** that captures dust at the source, keeping your air clean and your site compliant.

- Safety First: Operate entirely from the floor. No ladders, scaffolding, or stilts required.
- Dust Control: Available with a dual-vacuum HEPA cart system to meet silica dust regulations. The dust control is also available with a single vacuum system attached to the ceiling grinder frame itself.
- Self-Adjusting Head: The pivoting head automatically contours to the ceiling surface for an even finish without gouging.

## Engineered for Overhead Work

Eliminate operator fatigue and scaffolding costs.

### Cam-Lock Pressure System

Consistency is key. The PRO 1200 utilizes a **spring-loaded cam arm** that applies constant, even pressure to the ceiling. This prevents operator fatigue and ensures a uniform finish across the entire slab.

### Dust Control (PRO 1200V)

Breathe easier. The PRO 1200V model comes equipped with a floating **vacuum guard** with brush seals. When paired with our HEPA vacuum cart, it captures silica dust at the source.

### Pivoting Head Design

No gouging. The grinding head is mounted on a multi-axis pivot bearing, allowing it to **self-adjust** to the contours of the concrete automatically as you move.

### Winch Height Adjustment

Setup is fast. A heavy-duty winch allows you to raise and lower the mast to fit ceiling heights ranging from **7 feet to 12 feet** in seconds.

### Made in the USA

Built with pride in Bohemia, New York. We manufacture and assemble our grinders domestically to ensure rigorous quality control and long-lasting durability.

### Rapid Shipping

Downtime is expensive. We stock a massive inventory of finished units and spare parts, allowing us to ship most standard orders within **24 hours**.

How high can the unit reach?

The standard mast adjusts to reach ceilings between **7 feet and 12 feet** high. The height is easily adjusted using the manual winch system on the mast.

What maintenance does the flexible shaft need?

Every **50 hours** of operation, you should remove the inner core, wipe it clean, and re-lubricate it with a 1/16" coating of high-quality lithium grease. This prevents overheating and extends the life of the shaft.  

How do I attach a grinding stone?

The grinding head utilizes a **5/8"-11 R.H. thread** spindle. Simply thread your chosen grinding stone onto the spindle. Ensure the unit is unplugged (or spark plug removed) before changing accessories.

Can I use this for wet grinding?

While the manual primarily describes dry grinding with vacuum attachments for dust control, the unit is rated **IPX4** (splash resistant). However, always ensure you are using a Ground Fault Circuit Interrupter (GFCI) and proper extension cords marked for outdoor use (W-A) when operating in damp conditions.

How does the pressure system work?

You don't need to manually push the grinder against the ceiling. You set the initial height about 2 inches below the ceiling, then use the **tension handle** to cam-lock the head against the surface. This spring-loaded pressure ensures a consistent cut.
