Turn Your 20mm Linear Rails Into a Clean, Stable Router Sled — In Minutes

This slide connector is the missing link for DIY linear rail router sled builds.
It securely connects SBR20UU & SCS20UU slide blocks, adds effective dust collection, and includes a pre-drilled acrylic router plate—so you can flatten slabs faster, cleaner, and with confidence.

✔ Cleaner surfacing
✔ Smoother travel
✔ Less setup frustration

Connector & router plate only. Linear rails and slide blocks not included.

Why This Matters

The Problem with Most DIY Linear Rail Router Sleds

• Dust sprays everywhere, even with a vacuum

• Open-frame designs leak chips and fine dust

• Blank router plates require drilling and guesswork

• Improvised connectors flex or shift under load

The SpeTool Solution

This connector is purpose-built for 20mm linear rail sleds—not a generic add-on.

Key Benefits

Precision Connector for 20mm Linear Rail Systems

Engineered to link SBR20UU and SCS20UU slide blocks on 20mm linear rails, creating a stable, aligned platform for slab flattening and large-surface surfacing.

Integrated Dust Collection That Actually Works

An optimized brush seal surrounds the router bit area, capturing the majority of chips and fine dust and directing them into your dust collection system—keeping your workspace cleaner and visibility clear.

Pre-Drilled Clear Acrylic Router Plate

No guessing. No custom drilling.
The included transparent acrylic router plate is pre-drilled to fit most popular routers, allowing quick installation and better visibility during surfacing passes.

Rigid Yet Lightweight Aluminum Construction

CNC-machined aluminum provides strength without unnecessary weight.
The flush-fit frame + plate design minimizes gaps where dust typically escapes.

Fast Assembly, Easy Adjustment

Designed for DIY builders. Installs in minutes and allows quick positioning before routing—no complicated alignment process.
