FLEX XC 3401 Mini 4.5

FLEX XC 3401 Mini 4.5" Rotary Polisher Backing Plate


The FLEX XC 3401 VRG Mini Rotary Polisher Backing Plate is 4.5 inches in diameter and allows you to use 5 or 5.5-inch pads with your FLEX XC3401 polisher. The plate is designed specifically for this polisher and creates the forced rotation that sets the FLEX apart from other dual-action rotary buffers.

The secret to this polisher’s professional-grade performance is in the rotary backing plate. The unique design forces a true dual-action motion, rather than jiggling. The backing plate’s fit and design reduce vibration and give you a smoother, more comfortable motion around your boat hull and other areas.

Because of its special features, the FLEX XC 3401 VRG Polisher only accommodates a factory FLEX backing plate. Use a hex wrench to tighten the new plate securely onto the polisher. Add on a foam pad and you’re ready to polish your marine paint or gel coat!
