Toggle Clamp Latches

There are several types of quick-release toggle clamps available at Sierra Pacific Engineering and Products (SPEP), which are defined by their action. They are available in steel or stainless steel and can be zinc-plated steel or mill-finished if desired. Hand levers are available in inch and metric sizes.

Our selection of toggle clamps includes:

The most universally used toggle clamp is a vertical or vertical action hold-down clamp. Workpieces are secured by a bar that swings down and clamps tightly. When closed, the clamp’s handle is in a vertical or upright position.

• Hold-Down Horizontal Toggle Clamp

  The horizontal or horizontal action clamp is a variation of the vertical toggle clamp. The piece of manufacturing equipment applies holding force in a horizontal position. The low profile is beneficial when more clearance is needed or to keep the operator’s hand away from the clamp during operation.
  
  

• Push-Pull Clamp

  Another common toggle clamp is a push-pull toggle clamp. As the name suggests, it features a push or pull action to apply force in a direct, straight-line action. A push or pull-action latch toggle clamp is helpful when the operator needs it to apply force by pushing or pulling forward. When mounted vertically and locked, the clamp prevents components from falling forward.
  
  

• Latch Action Toggle Clamp

  This toggle clamp features a hook type that connects with a keeper. It works like an access latch to clamp, position, and seal.
  
  

• Heavy-Duty Toggle Clamp

  Heavy-duty toggle clamps are generally reserved for jobs that require additional holding capacity. These clamps are tested to provide 700+ lbs. of capacity.

Toggle clamps have a simple design but are made with key features that enhance their effectiveness. The clamping arm is connected to the workpiece and is actuated by the lever arm, while the base connects the clamp to an anchor. Depending on the type of toggle clamp, when in the locked position, the clamp can withstand forces of over 2,000 lbs., providing ample holding capacity for most situations.

Additional types of toggle clamps include:

• Plier action
• Cam action
• Plunger
• Swing

When choosing the ideal toggle clamp, consider the following:

• Application Requirements

  Some toggle clamps are better suited for certain applications than others. Load capacity and environmental conditions should factor into the selection process to ensure you’re choosing the right toggle clamp for the job. 
  
  

• Material Considerations

  Toggle clamps are available in various coatings and finishes. Most toggle clamps are made with pressed steel components with a zinc-plated finish. These materials are acceptable for a variety of applications. For marine applications and circumstances where toggle clamps must perform in rough conditions, corrosion-resistant finishes and stainless steel are ideal. 
  
  

• Size and Dimensions 

  A toggle clamp isn’t effective if it can’t hold the item. Knowing the measurements of the components you'll be working with can help you choose the proper hardware.
  
  

Installation and Maintenance

• Installation Steps

  Proper installation is crucial to ensure clamps perform as expected and to their fullest potential. Toggle clamps must be securely installed to a jig, moveable working surface, or table. The holes in the flanged base are where the clamp will be bolted down. Follow the manufacturer’s instructions for proper installation. If done correctly, you should be able to apply force to the toggle clamp without any movement.
  
  

• Maintenance Tips 

  Like any other piece of equipment, toggle clamps are susceptible to wear and tear. Users should routinely inspect their clamps for signs of aging and weak points. Users should keep toggle clamps clean and lubricated to ensure longevity of the component. 
  
  

• Troubleshooting Common Issues 

  Given their use, toggle clamps can become misaligned, creating challenges for the operator. Check to make sure toggle clamps are always aligned correctly and show no signs of wear and tear for precise usage.
  
  

Applications of Toggle Clamps

Toggle clamps are highly versatile, making them ideal for a wide range of applications in various industries, including but not limited to:

• Manufacturing – Assembly lines and machining processes for new products 
• Automotive industry – Vehicle assembly and car component manufacturing 
• Marine industry – Securing panels and equipment fastening 
• General instream use – Workshop setups for general work holding uses and jig and fixture construction

Toggle clamp latches are used for securing and holding workpieces in place during various industrial operations. Learn more about how toggle clamps work and why you need them.
