Splits Logs into Four Pieces • Tool-Free Drop-On Installation • Rotatable Design • Fits ED10T20 Only
Increase firewood-processing efficiency with the Boss Industrial CW-D1 4-Way Cross Wedge. Designed specifically for the Boss ED10T20 10-Ton Dual-Action Electric Log Splitter, this accessory divides compatible logs into four pieces during one splitting action, reducing the number of times each round must be repositioned and split.
The drop-on, lift-off design makes it easy to switch between the splitter’s standard wedge and four-way splitting. The attachment can also be rotated to accommodate varying log sizes and preferred firewood dimensions.
Key Features & Benefits

Four-Way Splitting
Divides compatible logs into four pieces to help reduce the number of splitting passes required. -
Tool-Free Installation
Drops onto the existing wedge without complicated installation or permanent modification. -
Easy Lift-Off Removal
Remove the attachment when the standard splitting configuration is preferred. -
Rotatable Wedge Design
Allows the wedge orientation to be adjusted for varying log and firewood sizes. -
Improves Firewood Productivity
Helps produce smaller pieces with less repositioning and repeated splitting. -
Designed for Dual-Action Splitting
Made specifically for the Boss ED10T20 electric splitter and its double-direction splitting configuration. -
Compact Accessory
Weighs approximately 10.5 lbs. for manageable installation, removal, and storage.
Compatible Log Splitter
The CW-D1 fits only:
- Boss Industrial ED10T20 10-Ton Dual-Action Electric Log Splitter
The ED10T20 is powered by a 2.5 HP, 115V electric motor and features a double-direction splitting system. Compatibility is based on the exact model number—not splitter tonnage, wedge height, or visual appearance alone.
Easy Drop-On Installation
The CW-D1 installs by placing it over the ED10T20’s existing splitting wedge. When four-way splitting is not required, lift the attachment off and return the splitter to its standard configuration.
Before installing, removing, rotating, or adjusting the attachment:
- Turn off the log splitter.
- Disconnect it from the electrical outlet.
- Allow all moving parts to stop.
- Relieve any trapped hydraulic pressure.
- Keep hands clear of the wedge and ram.
Adjustable Firewood Sizing
The cross wedge can be rotated to accommodate different cutting needs. Straight, consistently shaped rounds generally provide the best four-way splitting results.
Knotted, irregular, stringy, or oversized logs may place additional resistance on the hydraulic system and may split more effectively with the standard wedge.
Ideal Applications
The Boss CW-D1 is well suited for:
- Residential firewood preparation
- Fireplace wood
- Wood-stove fuel
- Processing straight-grained rounds
- Reducing repeated splitting passes
- Owners of the Boss ED10T20
- Indoor or outdoor electric splitting operations where permitted by the splitter manual
