Two precision systems, one trusted geometry

Jasper offers two performance levels within the same precision framework. The Standard model uses a hardened acrylic body for everyday projects, while the PRO model ships with industrial‑grade polycarbonate for enhanced durability. Both versions share identical precision geometry and repeatable pivoting action, giving you consistent results across sessions. The different materials translate to distinct warranties and wear resistance, allowing you to pick a setup that aligns with your project pace and workload.

• Standard: hardened acrylic, great for general shop use, limited lifetime warranty with registration
• PRO: industrial-grade polycarbonate, superior wear resistance, full lifetime replacement guarantee with registration

Why it stands out

Developed by an aerospace‑inspired engineer, the Jasper jig emphasizes obsessive accuracy rather than mass‑market compromises. The system’s reputation shines in its precision geometry, durability options, and a proven track record. A strong rating from verified users reflects satisfaction with performance and reliability across a broad range of projects.

• Same precise circle geometry in both Standard and PRO
• Material choice drives durability and warranty options

Usage and compatibility

For best results, verify your router compatibility before purchase. The Jasper 290 Circle Jig fits most compact, trim, and cordless routers, including popular models from Bosch, DeWalt, Makita, Milwaukee, Porter Cable, Ridgid, Ryobi, and more. It is not intended for full-size plunge routers; if you run a larger router, explore the Model 200/240 variants. A detailed compatibility chart is provided to help prevent mismatches and returns.

Craftspeople frequently use this jig to cut precise circular openings for speakers, create decorative rings for inlays, and produce templates with repeatable results. The system’s robust pivot and calibration features support consistent layouts across multiple pieces, making it a dependable option for both hobbyists and seasoned woodworkers.
