Why Gridplate?

Unlike traditional T-track spoilboards, PGC GridPlate™ provides mounting locations across the entire work surface, making it easier to secure odd-shaped parts, fixtures, fences, and accessories exactly where they are needed.

The flexible grid layout adapts to your project, helping reduce setup time while providing repeatable workholding for one-off and production work alike.

Built with a replaceable MDF spoilboard, precision-machined aluminum core, and moisture-resistant HDPE base, GridPlate™ is designed for accuracy, durability, and long-term use.

Build Your Workholding System


The PGC GridPlate™ is more than a fixture plate. Compatible accessories including rail clamps, precision fences, corner stops, and bench dogs allow the system to adapt to a wide range of projects and workflows. Start with the plate and expand your setup as your needs grow.

The Three-Layer GridPlate™ Construction

The PGC GridPlate™ combines the replaceability of a spoilboard with the durability and precision of a fixture plate through its unique three-layer design.

MDF Work Surface

The top layer is a precision-machined MDF spoilboard that provides a sacrificial machining surface. When it becomes worn from use, it can be resurfaced or replaced without affecting the accuracy of the GridPlate system.

6061 Aluminum Core

At the heart of the system is a solid 3/8" thick 6061 aluminum core. Every mounting point is threaded directly into aluminum, eliminating the pullout and stripping issues common with threaded inserts. Precision locating holes provide repeatable positioning for accessories and fixtures with repeatability better than 0.0005".

HDPE Base Layer

The bottom layer is machined from HDPE and serves as a protective barrier between the aluminum core and your CNC machine. The HDPE layer allows the aluminum core to be used directly as a fixture plate for aluminum machining with mist coolant, helping protect your machine table while providing a stable foundation for the system.

Together, these three layers create a workholding platform that offers the flexibility of a spoilboard, the durability of direct aluminum threads, and the precision of a fixture plate.

Why PGC GridPlate?

Why Does GridPlate Exist?

For years I struggled with the same fixturing challenges many CNC router owners face. Traditional spoilboards and T-track systems work, but they often require custom fixtures, time-consuming setups, and compromise between holding power and flexibility.

I wanted a system that combined the versatility of a spoilboard with the repeatability of a fixture plate.

GridPlate was designed to provide a dense network of locating and mounting points that make it easier to position workpieces, fixtures, fences, and clamps exactly where they're needed. Instead of building new fixtures for every project, users can quickly reconfigure their setup and get back to making parts.

The result is a modular workholding ecosystem that helps reduce setup time, improve repeatability, and make one-off or small-batch production more efficient.

What Problem Does It Solve?



Many CNC router users spend more time figuring out how to hold a part than machining it. GridPlate provides repeatable mounting and locating points across the entire work surface, making fixturing faster, more flexible, and more reliable. Combined with an expanding ecosystem of rail clamps, precision fences, corner stops, bench dogs, and other accessories, users can quickly configure setups for everything from one-off prototypes to small-batch production. Referenced directly from the PGC GridPlate locating system, accessories are manufactured to achieve less than 0.0005" repeatability, helping ensure consistent setups and accurate part positioning.


Why Aluminum Threads?


Traditional threaded inserts can loosen or pull out, while screws driven directly into MDF eventually strip the material. GridPlate uses a precision-machined aluminum core with directly threaded mounting holes, providing a stronger and more durable mounting system designed for years of repeated use.

How Accurate Is the System?


Precision fences, corner stops, and other locating accessories reference directly from the GridPlate locating system. Measured repeatability of less than 0.0005" allows setups to be recreated quickly and consistently.

Who Is It For?


GridPlate is designed for CNC router owners who want a more capable workholding system for woodworking, plastics, aluminum, prototyping, and small-batch production.
