Alpha(R) recognized the need to add a rigid version of this backer pad to its product line for straight edge or flat surface polishing applications. We realized that Ceramica, with a flexible backer pad, was too flexible for these applications and produced wavy finishes. Features High-Quality Backer Pad Is Super Rigid and Flat Eliminates The Wavy Finish When Polishing Hook and Loop Backed with A Long Life The Rigidness of The Pad Enables Work in Small Areas Such As Corners or Staircases Accepts Polishing Pads, Sandpaper and Felt Wheels Choice Among Fabricators, Tile Contractors, Monumentalists and Restoration Workers Fits On Most Popular Polishers and Grinders .dst-accordion { margin-top: 25px; border: 1px solid #FDDCC5; border-radius: 6px; overflow: hidden; } .dst-accordion-item { border-bottom: 1px solid #FDDCC5; } .dst-accordion-item:last-child { border-bottom: none; } .dst-accordion-toggle { display: none; } .dst-accordion-label { display: flex; justify-content: space-between; align-items: center; padding: 14px 20px; cursor: pointer; font-size: 17px; font-weight: 700; color: #231F20; background: #fff; transition: background 0.2s; } .dst-accordion-label:hover { background: #FFF3EB; } .dst-accordion-label::after { content: '+'; font-size: 22px; font-weight: 700; color: #F15C22; transition: transform 0.3s; } .dst-accordion-toggle:checked + .dst-accordion-label { background: #FFF3EB; } .dst-accordion-toggle:checked + .dst-accordion-label::after { content: '\2212'; } .dst-accordion-content { max-height: 0; overflow: hidden; transition: max-height 0.4s ease; padding: 0 20px; background: #fff; } .dst-accordion-toggle:checked ~ .dst-accordion-content { max-height: 5000px; padding: 15px 20px 20px; } Models GP35/8RG — 3.5in x 4.5in x 1.25in Property Detail Size 0.30 Maximum RPM 749173520242 Type 3.5in x 4.5in x 1.25in Threads 8466.91.0000 GP45/8RG — 4.25in x 4.5in x 1.25in Property Detail Size 0.40 Maximum RPM 749173520396 Type 4.25in x 4.5in x 1.25in Threads 8466.91.0000 GP55/8RG — 5in x 5in x 1.5in Property Detail Size 0.50 Maximum RPM 749173520549 Type 5in x 5in x 1.5in Threads 8466.91.0000 GP3M14RG — 3.5in x 4.5in x 1.25in Property Detail Size 0.30 Maximum RPM 749173520273 Type 3.5in x 4.5in x 1.25in Threads 8466.91.0000 GP4M14RG — 4.25in x 4.5in x 1.25in Property Detail Size 0.40 Maximum RPM 749173520426 Type 4.25in x 4.5in x 1.25in Threads 8466.91.0000 GP5M14RG — 5in x 5in x 1.5in Property Detail Size 0.50 Maximum RPM 749173520570 Type 5in x 5in x 1.5in Threads 8466.91.0000 GP3M16RG — 3.5in x 4.5in x 1.25in Property Detail Size 0.30 Maximum RPM 749173520297 Type 3.5in x 4.5in x 1.25in Threads 8466.91.0000 GP4M16RG — 4.25in x 4.5in x 1.25in Property Detail Size 0.40 Maximum RPM 749173520440 Type 4.25in x 4.5in x 1.25in Threads 8466.91.0000 GP5M16RG — 5in x 5in x 1.5in Property Detail Size 0.50 Maximum RPM 749173520594 Type 5in x 5in x 1.5in Threads 8466.91.0000 RGSPACER — 6.5in x 3in x 0.5in Property Detail Size 0.01 Maximum RPM 749173430039 Type 6.5in x 3in x 0.5in Threads 8466.91.0000 How to Use Select the appropriate grit for your current stage of polishing.
