What are the types of corner clamps?

	Although all corner clamps are used for similar projects, they are of different designs.
Single screw corner clamp
	This clamp is designed with a single screw that controls the movement of the jaws. All parts that make up the two jaws can be rotated to allow the clamp to grip workpieces of varying thickness while creating perfectly straight joints.
	This type of clamp is available in light duty and heavy duty models and can be used to hold workpieces made of all materials including wood, metal and plastic.
Twin screw corner clamp
	The twin screw corner clamp is often referred to as the corner clamp. The device has two screws that control each of the jaws separately. This means that when the user needs to clamp two workpieces of different thicknesses, they simply need to adjust one jaw at a time to fit each workpiece until both are securely clamped.
	The square edge of the clamp ensures that the connections are always at the perfect 90 degree angle, meaning no careless mistakes can be made. These clips are often used in pairs when making objects such as a picture frame to make sure opposite corners come together straight.
	Some models are available with a quick release mechanism for quick adjustment during clamping. The tool has two buttons, one on each jaw, that can be pressed to quickly move the adjustable jaw for faster workpiece assembly.
Welding angle clamp
	The Corner Welding Clamp is a heavy duty model specially designed for corner welding. This clamp is of a particularly strong and durable construction, as welding involves joining two parts through fusion, an action that puts a lot of pressure on the clamp.
	This type of angle clamp can usually be bolted to a drill press to securely hold material during drilling operations.
