Rover Backer Rod Installer — Walk-Behind Foam Rod Setting Machine

The Rover Backer Rod Installer is a walk-behind machine that dramatically speeds up the installation of polyethylene foam backer rod in horizontal saw-cut and expansion joints. A single operator pushes the Rover forward and it continuously feeds and seats backer rod directly from a mounted spool — at a precise, consistent depth — covering large floor areas in a fraction of the time compared to manual hand insertion.

Built for heavy-duty site use with an all-steel frame, it is the go-to machine for airports, warehouses, highways, and large-scale concrete floor projects where hundreds of linear metres of joint need to be filled efficiently.

• Fast one-person, walk-behind operation — continuously sets backer rod from a spool, covering large joint runs without stopping
• Adjustable insertion depth from 0″ to ¾″ — ensures consistent rod placement across the entire joint length
• Accepts joints from 1/8″ to 7/8″ wide and rod sizes from 1/8″ to 1″ diameter; extension kit available for spools up to 31″ wide
• Quick linchpin connections for fast setup and breakdown — no pipe threading required
• Includes two guide tubes to handle the full range of rod diameters without tool changes
• Sturdy all-steel construction built to withstand daily use on rough construction sites
• Compatible with the 640-Series hand insertion tools for starting, finishing, and cutting rod at joint ends
