FORSTER CT1010-CTB103 · 6.5 inches
More working length for the Original and Classic Case Trimmer
The long Forster base plate provides the greater mounting distance required by long cases or certain accessories on the manual case trimmer. It’s not just the 6.5-inch length that matters, but how it works with the trimmer model and the step in the process.

Check case length and trimmer

Black-Raptor assessment
CT1010-CTB103 is an original system component for the Forster Original Case Trimmer CT1010 and the Classic Case Trimmer CLCT00. It’s needed when the standard base or its adjustment range isn’t sufficient; on the Classic Trimmer, this long base is a standard part of the system.

Features with practical benefits


6.5-inch system length
The greater distance expands the usable range for long cases and certain Forster accessory applications.


Rigid I-beam design
Extruded aluminum resists the torsional forces generated during trimming, helping ensure a repeatable setup.


Original hole pattern
The base is designed for the housing and bearing side of the Forster system, avoiding trial-and-error during installation.


Avoiding limitations and the wrong purchase
The longer base is not automatically the better choice. Cases that are too short may fall outside the practical working range. With the Original Trimmer, first check the existing 1/2-inch adjustment using the outer holes. The collet, pilot, cutter shaft, and mounting hardware are not included with this item.
Technical specifications—and what they mean

Compatibility
Original Case Trimmer CT1010 and Classic Case Trimmer CLCT00; not universally compatible with other systems.

What's included
One long Forster case trimmer base plate CT1010-CTB103. Trimmers, collets, pilots, screws, and additional base plates shown are not included unless explicitly listed separately.
Use and safety
Empty the trimmer and stop the cutting tool before making adjustments. Mount the base flat and without tension, check all screws, and check clearance and the stop before inserting the first case. The case dimensions, pilot, and collet must match the caliber.
Frequently asked questions
Does the base fit the Original Case Trimmer? Yes. Forster lists it as an optional long base for the Original Case Trimmer CT1010. Can it be used with the Classic Trimmer? Yes. The 6.5-inch base is compatible with the Classic Case Trimmer CLCT00 and is its standard long system base. Do I need it for every long case? Not necessarily. The Original Trimmer first offers additional holes for 1/2-inch adjustment; the long base is only needed after that. Is a complete trimmer included? No. Only the base plate is included.

BLACK RAPTOR VERDICT
The right choice if your Forster setup demonstrably needs more base length. For short cases or a different trimmer system, however, it would be a typical wrong purchase.
