Horizontal toggle clamp STC HH open arm and horizontal base

In the clamped position, the lever is horizontal. Automatic and infinitely variable adjustment of the clamping height up to 35 mm while clamping force remains unchanged – without having to make manual changes to the position of the pressure screws.

Clamping force is variable up to 2,500 N depending on the adjustment of the set screw in the cantilevered joint. Sturdy, tempered metal sheets for a long service life. Hole pattern on the base plate designed to facilitate fast and secure clamping set-up for metric and imperial.

A horizontal toggle clamp is a type of fastening device used to hold or secure objects tightly together to prevent movement or separation through the application of inward pressure. In the context of the horizontal toggle clamp, “horizontal” refers to the orientation of the handle and the clamping bar or arm when the clamp is engaged.

Here are the key parts of a horizontal toggle clamp

1. Handle: The handle is used to operate the clamp. In the horizontal toggle clamp, the handle is typically in a horizontal position when the clamp is locked.
2. Clamping Arm or Bar: The clamping bar or arm holds the workpiece in place. In horizontal toggle clamps, the clamping arm is horizontal when it is in the locked position.
3. Pivot Points and Linkages: These mechanisms allow the handle and clamping arm to move. They create a ‘toggle’ action, which gives the clamp its name. The toggle action allows for quick locking and unlocking.
4. Base: The base of the clamp is designed to be mounted to a workbench, fixture, or other surfaces to provide stability.

How it Works:

• Unlocking: When the handle is lifted, the clamping arm swings open, releasing the workpiece.
• Locking: Pushing the handle down causes the clamping arm to swing shut, securing the workpiece. Due to the toggle mechanism, the clamping force is amplified, securely holding the workpiece without requiring excessive force from the operator.
• Applications: Horizontal toggle clamps are commonly used in woodworking, metalworking, and assembly operations. They are useful for holding workpieces in place during cutting, drilling, welding, or other processes.

A horizontal toggle clamp is a clamping device with a handle and clamping bar that are horizontally oriented when engaged. It uses a toggle mechanism to amplify the clamping force, enabling it to hold workpieces securely in place.

1. Horizontal Lever in Clamped Position: The lever remains horizontal when the clamp is in the secured position, indicating that the workpiece is held firmly.
2. Automatic and Variable Clamping Height: The clamp can adjust the clamping height automatically up to 35mm, eliminating the need for manual adjustments to ensure that various sizes of workpieces can be secured without compromising the clamping force.
3. Adjustable Clamping Force: The clamp’s force can be varied up to 2,500 N (Newtons), determined by the adjustment of a set screw in the joint. This allows for customizable pressure based on the specific requirements of the workpiece and task.
4. Durability: Made from sturdy, tempered metal sheets, ensuring that the clamp is durable and can withstand regular usage over an extended period.
5. Versatile Base Plate: The base plate comes with a hole pattern that supports both metric and imperial measurement systems, offering flexibility for various applications and ensuring a fast and secure setup.

Applications and Benefits

Applications: Such clamps are highly beneficial in manufacturing, assembly lines, woodworking, and metalworking where different sizes and shapes of workpieces need to be secured quickly and efficiently.

Benefits

• Efficiency: The automatic adjustment feature enhances efficiency, reducing the time taken to switch between different workpieces.
• Versatility: The adjustable clamping force ensures that both delicate and robust materials can be handled safely.
• Durability: The use of tempered metal sheets ensures that the clamp can withstand wear and tear, offering a long service life.
• Precision: The design ensures that the workpiece is held firmly in place, facilitating precise operations like cutting, drilling, or welding.
