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.

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.
