Choosing a Wilton C-Clamp for Your Shop
The right Wilton C-clamp comes down to frame style, throat depth, and the environment you work in. Use the guide below to match each series to your work.
Wilton Carriage C-Clamps
Carriage C-clamps use a standard carriage nut design for quick, reliable clamping in light to medium shop tasks. Three series cover standard reach, deep reach, and extra deep reach.
Wilton 140 Series Carriage C-Clamp
- Sizes: 1" – 8"
- Frame: Carriage style
- Reach: Standard
A compact, affordable carriage clamp for general bench work and light holding tasks across a wide range of sizes.
Wilton 540A Carriage C-Clamp
- Sizes: 2-1/2" – 14"
- Frame: Carriage style
- Reach: Standard
A heavier-duty carriage clamp with a wider size range — well suited for medium bench and fabrication work up to 14".
Wilton Deep-Reach Carriage C-Clamp
- Sizes: 1" – 3"
- Frame: Carriage style
- Reach: Deep and Xtra Deep
Built for clamping in tight spots where a standard throat depth won't reach — available in deep and extra deep reach versions.
Wilton Standard Depth and Square Throat C-Clamps
Standard depth and square throat Wilton C-clamps offer a solid forged frame for general and precision shop clamping. Square throat models add extra rigidity for heavier holding work.
Wilton Standard Depth C-Clamp
- Sizes: 2" – 12"
- Frame: Standard depth

Wilton Square Throat C-Clamp
- Sizes: 4" – 8"
- Frame: Square throat
- Series: 4400
The square throat frame adds rigidity under load — a good choice for heavier clamping tasks where a round frame would flex.
Wilton Classic C-Clamps
Classic Wilton C-clamps are built on proven forged frames for reliable general shop use. Three finishes are available: standard, Columbian, and Hi-Vis Safety.
Wilton Classic Columbian C-Clamp
- Sizes: 2" – 12"

A dependable general-purpose C-clamp for woodworking, metal work, and assembly across a full range of opening sizes.
Wilton Classic Hi-Vis Safety C-Clamp
- Sizes: 2-1/8" – 12-1/4"
- Finish: Hi-Vis Safety
- Series: 400SF
The same Classic frame with a high-visibility finish — easy to spot in busy shops where clamp visibility matters.
Wilton Spark-Duty C-Clamps
Spark-duty Wilton C-clamps use copper-plated contact surfaces to reduce spark risk in welding and grinding environments. Available in standard and Hi-Vis finishes.
Wilton Spark-Duty C-Clamp
- Sizes: 2-1/8" – 12-1/4"

- Contact surface: Copper-plated
- Series: 400CS
Adds a high-visibility finish to the spark-duty build — a good fit for busy fabrication shops where clamp location needs to be clear at a glance.
Wilton Brute-Force C-Clamps
Brute-Force Wilton C-clamps are built for heavy-duty clamping with high clamping force ratings and rugged frames. The standard series handles open-throat work and the O Series Bridge handles tight-reach applications.
Wilton Brute-Force C-Clamp
- Sizes: 3" – 12"
- Frame: Open throat
- Series: 100
High clamping force in a rugged open-throat frame — built for heavy fabrication and metalworking tasks that standard clamps can't handle.
Wilton Brute-Force O Series Bridge C-Clamp
- Sizes: 1-3/8" – 12" jaw opening
- Frame: O Series Bridge
- Series: FC
The bridge frame and full-closing spindle make this the right choice for tight-reach clamping and thin stock where a standard open throat won't fit.
