Carter F.A.S.T Fence Alignment Tool — Precise Blade-to-Fence Alignment with Magnetic Bars

Meet the Carter F.A.S.T Fence Alignment Tool

The Carter F.A.S.T Fence Alignment Tool is a compact, magnetized aid designed to sit on your saw blade and help you establish a precise sweet spot for your fence. With a simple setup, you can aim for repeatable, clean lines across your projects.

What makes F.A.S.T different

Its magnetic design allows the bars to attach to the blade, and a notch cradles the teeth so the tool sits flush against the blade body. When your setup is close to square within a quarter inch, straight cuts become more achievable, providing a dependable baseline for your work. The combo pack expands your options by including multiple bar thicknesses to dial in exact blade-to-fence clearance.

• FAST bar enables accurate measurement from blade to fence
• Suitable for measuring router bit height or depth when needed
• Notch keeps blade teeth resting flat against the blade for stability
• Ruler on the bars helps set the distance between fence and blade

What you get in the combo pack

Five magnetic bars are included: 1/8", 3/16", 1/4", 3/8", and 1/2". They let you square the fence to the blade and measure exact gaps, then extend magnetic bars together to form wider widths. This flexibility supports a range of fence-to-blade configurations.

• Five precise bar thicknesses for exact alignment
• Magnetic assembly lets you create custom widths on the fly
• Easy-to-read scale helps set precise distances

Real-world use and tips

Think of cabinet face frames, trim work, or shelving where repeatable cuts matter. Place the F.A.S.T on the blade, slide the fence to your desired distance using the ruler, and lock in the setup with confidence. The notch seats on the teeth, helping you maintain a flat contact while you measure and cut. Use it to check both the blade-to-fence gap and, when needed, the height of routing bits.

• Align the fence square to the blade for best results within the tool's range
• Combine magnetic bars to reach wider gaps between blade and fence
