About This

• [Improve Efficiency & Say Goodbye to Bending Over] This tool is designed for quick and precise installation of backer rods. It presses the backer rod evenly deep into the joint, ensuring consistent depth and improving the efficiency and quality of caulking while saving caulking agent and time.
• [Compatible with US Standard Threaded Rods for Standing Use] The tool interface uses US standard threaded holes, allowing direct connection to your own US standard threaded rods, This allows you to install backer rods in concrete joints while standing. No more frequent bending over, significantly reducing lower back and back fatigue—ideal for long-term site work or large-area road projects. (Note: This kit does not include an extension rod; you will need to prepare your own US standard threaded rod.)
• [Height Adjustable + Dual Auxiliary Wheels] ① CENTER WHEEL - The pressing depth can be easily adjusted by manually tightening the screw, flexibly adapting to different caulking depth requirements. ② SIDE AUXILIARY WHEELS - These ensure constant contact with the ground for stable support during operation. Regardless of depth, it maintains balanced support, ensuring precise and consistent results with every application and preventing seal quality issues caused by depth deviations.
• [Multiple Sizes Available] Equipped with four different width center wheels (sizes: 1/8", 1/4", 3/8", 1/2"), allowing selection of the appropriate roller for different joint widths and backer rods widths. The included hex wrench makes center wheels replacement easy, flexibly adapting to joint widths and meeting diverse application needs.
• [Wide Application] Ideal for road works, building construction, and interior sealing applications. Its versatile design makes it suitable for a wide range of applications, improving work efficiency and ensuring proper backer rod placement in all sealing and caulking projects.
