Magnetic Anti-Flashback Risers for Laser Cutters, 1/2in Precision Lift Material Hold Down with 43mm Heavy-Duty Magnet, Clear Acrylic Spacer & Metal Knurled Nut for Honeycomb Bed, 6 pack

Industrial-Grade Stability: Built with a 43 mm heavy-duty magnet, these risers lock securely onto steel honeycomb beds and stay put even during high-speed cutting, unlike lightweight plastic supports that shift mid-job, they keep your material exactly where it should be for consistent results | Clean 1/2" Lift: 6.5 mm magnetic base combined with 6 mm clear acrylic spacer creates a true 1/2-inch lift, this allows clean airflow underneath, significantly reducing flashback and leaving wood, leather, and acrylic smooth and no-burn on the back | Premium Metal Hardware: Oversized 30 mm metal knurled nut tightens smoothly by hand for a solid, secure hold, paired with crystal-clear acrylic spacers, it maintains a clean, professional look with minimal visual obstruction for laser camera alignment | Helps Flatten Warped Materials: Wide flat nut distributes pressure evenly, helping hold down slightly warped wood, leather, or acrylic. This keeps materials flat and within optimal focus range for sharper engraving and more accurate cuts | Built for Long Runs: Constructed with heat-resistant metal hardware and thickened acrylic, these risers handle laser heat far better than injection-molded parts, durable M4 threaded design is made for daily use in busy laser workshops
