Rockler Router Table Box Joint Jig with Three Finger Widths - 1/4 in, 3/8 in, 1/2 in Indexing Keys

Overview

Bring professional precision to your box joints with the Rockler Router Table Box Joint Jig. Designed for small to medium boxes, it pairs a stable MDF platform with a melamine coating for smooth sliding and reduced tear-out. Interchangeable indexing keys ensure consistent finger spacing across projects, with three widths to cover common box sizes: 1/4 in, 3/8 in, and 1/2 in.

Precision, control, and repeatability

The hardened brass indexing keys seat precisely and swap easily, storing in dedicated slots on the sled so you aren’t chasing parts between cuts. The long sled keeps the jig square to the router bit, helping you maintain alignment through every pass.

• Interchangeable indexing keys ensure uniform finger spacing for repeatable joints across multiple boxes.
• Three finger widths expand your range of box sizes without reconfiguring the jig.
• Brass keys resist wear for lasting accuracy; quick swaps minimize downtime between setups.

Durable build and smooth operation

The MDF platform is melamine-coated to provide low-friction sliding and extra durability. The platform locks into a 3/4 in miter slot with ergonomic knobs, while the included glass-filled nylon sled offers steady tracking during passes.

• Melamine-coated MDF reduces friction and helps protect your workpiece.
• Ergonomic knobs enable secure, comfortable operation and quick locking into the miter slot.
• Sturdy nylon sled supports steady guidance for clean routing results.
