Extension & Small Blocks
Modular Setup Aids for Welding Tables and CNC Machining

Extension Blocks and Small Blocks are essential components in any modular fixturing system, enabling flexible part positioning, height adjustments, and precision alignment. Designed to work seamlessly with 2D and 3D clamping systems, these blocks offer stability and repeatability during welding, assembly, and machining operations.

Made from high-grade hardened steel or stress-relieved cast iron, each block is precision-machined to ensure perfect flatness, squareness, and parallelism—ideal for production environments where accuracy and efficiency matter.

🔧 Technical Specifications
Material Options:

Hardened Tool Steel (tempered for wear resistance)

Cast Iron (HT200 / GG20, stress-relieved)

Surface Finish: Ground on all functional surfaces

Tolerances:

Flatness: ±0.01mm

Squareness: ±0.02mm

Mounting Compatibility:

16mm or 28mm hole systems

Zero-point locating bushings

Tapped or slotted holes (customizable)

🛠️ Applications
Height Spacers: Elevate workpieces or tooling to specific levels for consistent setups

Support Blocks: Provide stable support under parts, jigs, or clamps

Extension Blocks: Extend reach for clamps or positioning tools in modular setups

Fixturing Base: Serve as foundational elements in custom fixtures or modular assemblies

Bridge Gaps: Span across welding table holes or between fixtures

✅ Key Features
Precision-ground for dimensional accuracy and repeatable setups

Compatible with all standard modular welding tables and CNC fixtures

Durable, wear-resistant materials designed for long service life

Available in a variety of thicknesses and geometries

Easily stackable and modular for flexible fixturing configurations

Custom sizes, hole patterns, and finishes available upon request. Suitable for fabrication shops, CNC machining centers, R&D labs, and fixture designers who need versatile and dependable setup tools.
