RSP MPS Magnetic Preload Ring (11″, 14″, 16″)




Runyon Surface Prep is proud to announce the introduction of an innovative tool holding system for power trowels, auto scrubbers, and swing machines. The Magnetic Preload System allows for the fast and efficient changing of any 3″ velcro-backed tooling on a standard 11″, 14″, 16″, or 17″ pad driver. The system consists of a stainless steel ring that bolts to the pad driver and high-density polymer tool holder rings with embedded magnets on one side and six recessed slots for 3″ velcro backed puck style tools on the other.

Each MPS set-up comes with 2 of these tool holder rings. However, this ring by itself is ideal if you want to put all tool grits on rings at the beginning of the polishing process so they are loaded and ready to stick under the machine for each tool change. Purchase 10 of these rings for each extra tool grit step.

You can run 3, 4, or 6 tools on each ring. This means a total of 30, 40, or 60 tools for each 8′ trowel machine (10 MPS mounts total). Attach Turbo Tulips, Copper Transitionals, or Wet Slicks to these rings.
