• Vortech spinners are spun from Aluminum sheet - not molded/cast from brittle material, or machined out of expensive bar stock
• Precision CNC machined to exacting tolerances
• Designed to be strong, yet light weight
• Spinner cone locks into backplate to stop spinner cone expansion
• Backplate is knurled for positive grip between engine’s drive washer and your propeller
• All Vortech Spinners start life the same way - as a flat piece of aluminum sheet which has a CNC machined tip pressed into the center
• This disk is then, spin-formed to shape and turned to high precision
• After the cone is machined, it is polished to a beautiful reflective finish
• Vortech spinners have cutouts with clearance for popular sizes of props
