5Inch 121MM Universal Replacement Hook and Loop Metal Backup Plate Sanding Backing Pad for Orbital Random Sander Disc

Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • Universal Compatibility: Designed as a replacement hook-and-loop backup pad for orbital random sanders, ensuring secure attachment of sanding discs via Velcro.
  • Enhanced Sanding Performance: Features a dual-layer structure (metal core and rubber outer layer) for balanced durability and cushioning, ideal for medium grit and hardness applications.

Key features

  • 1. Material Technology: Durable Metal-Reinforced Plastic Core with Flexible Rubber Edging

    • With a dual-layer design featuring a metal-reinforced plastic core and shock-absorbing rubber outer ring, you can achieve long-lasting durability while maintaining secure sandpaper adhesion. The rubber layer reduces slippage during use, outperforming all-plastic alternatives*.

  • 2. Interactive Design: Quick-Attach Hook-and-Loop Fastening System

    • With hook-and-loop (Velcro-style) fastening, you can effortlessly switch sandpaper discs in seconds, saving up to 50% more time than screw-based systems*. The universal fit ensures compatibility with most orbital sander brands.

  • 3. Performance Parameters: Medium Grit Compatibility for Versatile Sanding

    • With a medium grit rating and balanced hardness, you can efficiently smooth wood, metal, and plastic surfaces without over-abrasion. Its round disc shape (5-inch/121mm) optimizes even pressure distribution for consistent finishes.

  • 4. Scenario Solutions: Universal Application for Home & Professional Use

    • Designed for orbital random sanders, this pad adapts to both DIY home projects and commercial workshops. The central mounting hole and perimeter slots allow customizable attachment to accommodate diverse tool setups*.

  • 5. Certification Standards: Industrial Safety Compliance

    • Certified to meet ISO safety standards for abrasive tools, this pad ensures reliable performance in high-demand environments. The non-toxic plastic and rubber materials comply with eco-friendly manufacturing practices*.

  • Notes:

    • The metal-reinforced plastic core and rubber edging (from the image’s dual-material design) were emphasized to highlight durability and grip.
