834D ZINC GROOVER 6X4 1/4RAD

Overview

The Marshalltown 834D Zinc Groover (834D) is designed for hand-grooving concrete flatwork to create controlled expansion and contraction joints.

Technical Features

• Zinc blade construction: Provides a smooth, non-reactive surface that glides cleanly through fresh concrete without sticking or dragging.
• 6 in blade length with 4 3/8 in blade width: Delivers a wide, stable contact footprint, reducing rocking and maintaining consistent groove alignment across the slab surface.
• 3/4 in groove depth and 3/8 in groove width: Produces a precisely dimensioned joint channel that meets standard control joint depth requirements relative to slab thickness.
• 1/4 in curve radius: Produces a defined, rounded joint edge that reduces chipping and improves the long-term durability of the joint perimeter.
• DuraSoft handle, 4 1/2 in length: Provides a cushioned, fatigue-reducing grip during extended grooving operations on large concrete pours.
• 3.91 lb tool weight: Offers sufficient mass for controlled downward pressure without requiring excessive operator force on fresh concrete.

Applications

• Cutting control joints in freshly poured concrete flatwork such as sidewalks, driveways, and slabs-on-grade.
• Creating expansion and contraction joints that direct crack propagation to predetermined locations, preserving slab integrity.
• Finish grooving operations where a clean, uniform joint profile is required for both structural and aesthetic results.
• Use along a straightedge guide where the 6 in blade length provides consistent edge-to-edge tracking.
