Rockler Benchtop Board Slab Flattening Jig | Precision Router Sled for Slabs & Resin Projects

Meet the Rockler Benchtop Board Slab Flattening Jig, a compact router sled designed to keep small slabs, end grain boards, and resin pieces flat and true. Its unobtrusive footprint sits neatly on a workbench, helping you route precise surfaces without a bulk drum sander. Built for steady performance, it supports your project flow from rough stock to finished pieces, while leaving room for your favorite bits and setup adjustments.

Designed for versatility on a compact work surface, the jig rests securely on a bench or shop stand. It lets you flatten faces on smaller slabs, end grain boards, or resin charcuterie boards, delivering a flat, ready surface that can move quickly into finishing steps. The setup remains accessible as you fine tune the process, making repeated passes more predictable.

Built for versatility on a compact workbench

Precision movement is at the heart of this jig. Precision guide rails guide the router with a low friction carriage, producing a flat finish while reducing tear out. The shearing action helps you preserve delicate edges and minimize sanding, so you can progress from stock to finished panel with less back and forth.

• Rigid extruded aluminum base rails attach firmly to your work surface with included hardware
• Slots in the rails allow fine tuning to keep everything parallel during routing
• The reinforced plastic router carriage features low friction pads and safety catches for controlled operation

Safe, compatible, and ready to use

Compatibility is a key feature. The pre drilled clear acrylic baseplate accepts many mid sized routers, providing a reliable and safe working platform that you can trust day after day.

• Includes: two cross rails, two base rails, two cross rail end caps, two base rail end caps, two glide bases, one router baseplate, one router carriage, and the complete set of assembly hardware
• Router, bit, and workpiece are not included, giving you the freedom to pair with your current setup

What you can achieve

With the Rockler jig you can tackle smaller slabs, end grain boards, and resin projects with confidence. Expect surfaces that respond well to light finishing and a clean edge profile, all while maintaining accuracy and repeatability across sessions. In daily use, this benchtop sled offers a practical path to true surfaces on small to medium slabs while preserving tool control and work area, making it a flexible addition to many woodworking workflows.
