Splits Logs into Four Pieces • Tool-Free Installation • Rotatable Design • Fits Select Boss Electric Splitters

Increase firewood-processing efficiency with the Boss Industrial CW-S 4-Way Cross Wedge. Designed specifically for select Boss electric log splitters, this accessory divides compatible logs into four pieces during a single stroke, reducing the number of passes needed to produce smaller firewood sections.

The simple drop-on, lift-off design installs without tools and makes it easy to switch between standard two-way splitting and four-way splitting. The wedge can also be rotated to accommodate different cut sizes.

Key Features & Benefits

  • Four-Way Splitting
    Splits compatible logs into four pieces during one stroke for faster firewood production.
  • Tool-Free Installation
    The drop-on design allows the wedge to be installed and removed without tools.
  • Rotatable Configuration
    Rotate the wedge to adjust the resulting firewood size for different applications.
  • Improves Productivity
    Reduces the number of splitting passes required compared with the standard two-way wedge.
  • Compact Accessory
    Weighs approximately 4 lbs. for convenient handling, installation, and storage.
  • Made for Select Electric Splitters
    Designed specifically for the compatible Boss models listed below.

Compatible Boss Log Splitters

The CW-S 4-way wedge fits only the following Boss Industrial electric log splitters:

  • EC5T20
  • ES7T20
  • ED8T20

This accessory is not universal. Similar-looking Boss splitters may use different wedge and beam configurations. Confirm the complete model number on the splitter’s identification label before ordering.

Easy Drop-On Installation

The CW-S installs by dropping it over the splitter’s existing wedge. No permanent modification or tool-assisted installation is required. When four-way splitting is not needed, lift the attachment off and return to the machine’s standard splitting configuration.

Always turn the splitter off and disconnect it from its power source before installing, removing, rotating, or adjusting the wedge.

Adjustable Firewood Sizing

The wedge can be rotated to change the orientation of the cross-cutting wings. This allows the operator to adjust the resulting piece sizes based on the diameter of the log and the desired firewood dimensions.

Straight, consistently shaped rounds generally provide the best four-way splitting results. Knotted, irregular, stringy, or unusually small logs may split more effectively using the standard wedge.

Ideal Applications

The Boss Industrial CW-S is well suited for:

  • Residential firewood preparation
  • Fireplace wood
  • Wood-stove fuel
  • Cabin and seasonal-property use
  • Processing straight-grained rounds
  • Owners of compatible Boss electric splitters
  • Users seeking fewer splitting passes
