Marshalltown Shockwave 9 Inch Hole Spacing Blade 10 Ft. Power Screed Board

Description

Standardized nine-inch hole spacing allows you to mount this high-frequency screed board to multiple competitive powerhead brands without custom drilling. The Marshalltown Shockwave 10 Foot Screed board delivers reliable aggregate consolidation across mid-sized slab bays. An extruded magnesium profile floats paste smooth. Operators must clean concrete from bolt holes between uses to prevent thread bind.

Extruded magnesium alloy forms the Shockwave blade profile, delivering structural rigidity with superior vibration conduction across ten-foot pour spans. The blade profile features an engineered curl face that pushes aggregate forward while the flat rear base floats the surface flat. Net blade weight registers 13.5 lbs, spanning 120 inches with a standard nine-inch bolt center mounting pattern that fits leading powerheads.

Key Features of Marshalltown 32407

Commercial concrete finishers and residential flatwork contractors bolt this ten-foot blade onto powerheads for garage floors, driveways, and commercial slabs. Compare dealer pricing to buy Marshalltown 32407 power screed boards for universal power unit compatibility.

• Industry standard nine-inch bolt hole spacing fits Marshalltown, Magic Screed, and MBW units.
• Extruded magnesium alloy transfers high-frequency vibration to consolidate dense aggregate.
• Ten-foot working width fits standard residential garage slabs and commercial bays.
• Engineered curl blade profile rolls surplus concrete forward to eliminate hand shoveling.
• Flat trailing edge seals the concrete surface to float rich paste cream to top.
• Lightweight thirteen-pound magnesium profile reduces worker arm fatigue on long runs.
• Non-corrosive metal construction resists harsh chemical concrete accelerators and salt.
• Rigid extrusion cross section prevents blade curl under high vibratory force.

Magnesium Resonance Load Deflection Metrics

Center-span deflection measures 0.035 inches across the ten-foot unsupported length under operating load. When coupled to a screed power unit running at 7,000 VPM, vibration amplitude measures 0.038 inches at the center mount and 0.031 inches at the outer tips. The magnesium extrusion transfers vibratory energy four inches deep into low-slump concrete mixes. Bottom edge straightness holds within 0.022 inches total indicator reading along the 120-inch length. Torsional twist remains under 0.30 degrees under full aggregate head.

Garage Slab Operator Service Realities

Weighing under fourteen lbs, a solo finisher can pull this screed across ten-foot garage bays without helper lines on medium-slump concrete. The flat float bottom glides across edge forms without binding or gouging lumber. Do not buy this ten-foot blade for wide twenty-foot warehouse pours or narrow two-foot trench cuts. Residential driveway contractors and patio finishers gain outstanding leveling speed from this blade.

• Wash concrete paste from the extrusion profile with clean water after each pour.
• Inspect the bottom float edge for stone gouges and file burrs smooth.
• Check mounting bracket bolt torque before connecting the vibratory powerhead.
