Alpha® Corner RulersAlpha® Corner Rulers give fabricators a fast, repeatable way to mark, cut and grind the square corners of glass, tile, stone, porcelain, plastic and wood. Each set delivers seven of the most common corner patterns in a stainless-steel storage case — choose the Radius Set for rounded corners (3/8" to 1-1/2") or the Straight Set for 45° chamfered corners. Used with the Alpha® Corner Nipper or a standard profile wheel, the rulers dramatically reduce corner preparation time on countertops and architectural panels.Features Mark, cut and grind square corners on glass, tile, stone, porcelain, plastic and wood Radius Set (CRRSET7): seven rounded-corner radii from 3/8" to 1-1/2" Straight Set (CRSSET7): seven 45° chamfer patterns from 3/8" to 1-1/2" Stainless-steel storage case keeps the seven patterns organized on the jobsite Combine both sets for 14 patterns covering the full corner-shape range Pairs with the Alpha® Corner Nipper and stone/glass profile wheels .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 / Part Numbers Part No. Type Description UPC CRRSET7 Radius Set Corner Ruler Radius Set w/Stainless Steel Case (7 patterns) 749173650147 CRSSET7 Straight Set Corner Ruler Straight Set w/Stainless Steel Case (7 patterns) 749173650222 How to Use Select the pattern that matches the finished corner profile required by the design (radius dimension for CRR; chamfer length for CRS). Position the ruler against the square corner of the slab, panel or tile and trace the line with a fine marker or scribe. For glass and thin tile, follow up with a glass cutter or the Alpha® Corner Nipper to remove the bulk material. For stone, porcelain and countertop material, rough-cut with a wet saw, then refine to the line with a profile wheel or hand polisher. Return each ruler to the labeled slot in the stainless-steel case to prevent loss of the smaller patterns.
