Elevate Your Router Table with Premium Precision

The JessEm Mast-R-Fence III sets a new standard for router table accuracy, aesthetics, and durability. Manufactured entirely in Canada, this fence brings together advanced materials and smart design to deliver a tool that’s as beautiful as it is functional.

Solid Build, Premium Components

  • Flat, rigid base: A red phenolic base ensures a perfectly flat, stable platform for your fence setup.
  • Anodized aluminum extrusion: The upright fence body is built from precision-machined 6061 aluminum with a sleek black anodized finish for strength and style.
  • Machined “high-boy” knobs: Unlike typical plastic knobs, the Mast-R-Fence III uses knob controls crafted from 6061 aluminum for durability and a premium feel.
  • Maple sub-fences: The two split sub-fence faces are made of torrefied maple, cut, machined, and laser-engraved in JessEm’s facility. They can be tool-free adjusted from behind.
  • Robust hardware: All fasteners and components are stainless steel or aluminum—no plastic parts where strength matters.

Precision & Adjustment Features

  • Shimming capability: Included shimming bars let you offset the outfeed fence face by 1/32" or 1/16" for jointing or fine-tuning. They store neatly on the back when not in use.
  • Micro adjuster compatibility: The fence is ready to accept JessEm’s Micro Adjuster (04550) for ultra-fine fence positioning (1/256" graduations).
  • Dual dust port support: The fence supports a 2-1/4" inside / 2-1/2" outside diameter dust connection, letting you connect your vacuum system cleanly behind the split fence.

Dimensions & Compatibility

  • Fence length: 36" (approx.)
  • Height: ~3-5/8" (upright extrusion)
  • Fits tables: up to 32" wide
  • Table thickness allowed: 3/4" to 1-1/2"
  • Works on all JessEm tops and can mount via direct side brackets or T-slots spaced 17" apart.

NOTE: Compatible with Infinity Plycore Router Table Tops, RTT-002
NOT COMPATIBLE WITH Infinity Cast Iron Router Table Tops.

Hazel D. ★★★★★

The machining on this fence is so precise that setup takes half the time it used to, and the fact it’s built entirely in Canada gives me confidence it’ll outlast my table saw. Even the finish looks great sitting on the router table—form and function actually meet here.

Madison M. ★★★★★

After fighting with my old split fence for years, the smooth micro-adjustment on this one is a total game changer. The dust collection port fits my shop vac hose perfectly with no adapter needed.

Sofia N. ★★★★★

The aluminum extrusion is rock solid with no flex at all, and the micro-adjustment dial lets me dial in perfect bit alignment in seconds. It took me maybe 20 minutes to get it mounted and squared up on my table.
