Part of a 25-year engineer-founded legacy with 100,000+ units sold. |  ONE PRECISION SYSTEM  TWO PERFORMANCE LEVELS  Both Standard and PRO use Jasper's legendary CNC-machined pivot holes and precision calibration disc for repeatable accuracy. Choose Standard (hardened acrylic) for everyday projects, or PRO (industrial-grade polycarbonate) for maximum durability and lifetime peace of mind. Same precision geometry. Different materials. Different warranties. |  ENGINEER-FOUNDED PRECISION  Created by aerospace-era engineer Les Jasper who demanded obsessive accuracy. Not mass-market compromisethis is engineer-level precision proven through 25 years and 100,000+ units sold across the complete Jasper system. The Jasper family of circle guides has earned 4.6 across 2,393 verified reviews. When craftspeople comparison-shop for circle jigs, they choose Jasper. Now you know why. | Bullet 4:  STANDARD VS PRO  MATERIAL MAKES THE DIFFERENCE  Standard: Hardened acrylic construction, limited lifetime warranty against manufacturing defects with registration, perfect for everyday shop and DIY use. PRO: Industrial-grade polycarbonate with superior strength and wear resistance, full lifetime replacement guarantee with registration, built for professionals and high-volume users. Both deliver identical Jasper precision. |  ROUTER COMPATIBILITY CHECK REQUIRED  Fits most compact, trim, and cordless routers including Bosch Colt, DeWalt DCW600\/DWP611, Makita XTR01, Milwaukee M18 FUEL, Porter Cable, Ridgid, Ryobi, and more.
