How Does the Inline Fabrication Quick Change Top Plate Work?

Reloaders often run multiple presses or specialized tools, and bench space quickly becomes a challenge. Inline Fabrication’s Quick Change system solves this problem with a modular mounting design that lets you swap presses and accessories in seconds without sacrificing stability.

At the center of this system is the Quick Change Top Plate, a precision-machined plate that locks into the Quick Change Ultramount base. Understanding how it works is essential for anyone looking to streamline their reloading bench setup.


Quick Answer: How the Top Plate Works

The Inline Fabrication Quick Change Top Plate bolts directly to your reloading press (or tool) and then locks into the Quick Change Ultramount Base. Once engaged, it creates a rigid, vibration-free platform. To swap tools, simply unscrew the wing nuts, remove the plate, and drop in another top plate already pre-mounted with a different press or accessory.

This design allows one bench and one Ultramount base to securely host multiple presses, without drilling new holes or permanently mounting each tool.


Anatomy of the Quick Change System

To fully understand the operation, let’s break down the components:

1. The Ultramount Base

  • Constructed from 3/16" steel, powder coated for durability.
  • Serves as the permanent fixture mounted to your bench.
  • Available in dedicated and Quick Change models.

2. The Quick Change Top Plate

  • Precision-machined plate specific to each press.
  • Includes the correct hole pattern and hardware for plug-and-play mounting.
  • Slides into the base and locks down with alignment pins and screws.

3. Locking Mechanism

  • Uses thumb screws or wing nuts to secure the plate.
  • Creates a solid, no-wobble fit, critical for maintaining consistency in reloading.

Step-by-Step: How to Use the Quick Change Top Plate

Step 1: Mount Your Press to the Plate

Bolt your reloading press, priming tool, or case trimmer to the Quick Change plate. Each plate is specifically designed for the tool you’re using. For example, the Wilson Single Stage Reloading Press requires its own dedicated top plate.

Step 2: Insert the Plate Into the Base

Slide the plate into the Quick Change Ultramount base. It will align automatically thanks to its precision-machined guides.

Step 3: Lock It in Place

Tighten the wing nuts (or cam locks, depending on the model). This removes play and secures the tool for operation.

Step 4: Swap Tools as Needed

When it’s time to change setups, loosen the locks, pull the plate out, and drop in another tool. The swap takes less than a minute.


Benefits of the Quick Change System

Save Bench Space

Instead of dedicating permanent bench space for multiple presses, one Ultramount can host all of them.

Increase Flexibility

Reloaders often alternate between tasks, such as sizing, seating, trimming, and priming. The Quick Change design makes these transitions seamless.

Maintain Stability

Unlike makeshift bench clamps or bolt-down swaps, the Ultramount and top plate combination provides rock-solid stability, ensuring safe and precise operation.

Future-Proof Your Setup

If you add new presses or accessories, simply order a new top plate instead of building a new bench mount.


Comparing Quick Change vs. Dedicated Ultramount

Inline Fabrication also offers a Dedicated Ultramount, which is permanently set up for one tool. While dedicated mounts maximize rigidity, the Quick Change system is more versatile for reloaders running multiple presses in limited space.

  • Quick Change: Best for reloaders with multiple presses or tools.
  • Dedicated: Best for reloaders who run one press exclusively.

Maintenance and Best Practices

  • Check locks regularly: Always ensure the plate is tight before operating the press.
  • Clean mounting points: Keep the slots free of debris for smooth insertion/removal.
  • Have spare plates ready: Order multiple top plates so each tool has a permanent mount and no re-bolting is needed.

Conclusion

The Inline Fabrication Quick Change Top Plate is one of the most efficient upgrades you can add to your reloading bench. By combining precision fit, tool-specific machining, and a fast-swap design, it lets you run multiple presses on a single Ultramount without giving up strength or safety.

If you’re ready to make your bench more organized and versatile, start with a base and add the Quick Change top plates you need. It’s an investment that pays off every time you swap tools in seconds instead of hours.
