Description and Usage of C-clamps
– C-clamps or G-clamps are made of steel or cast iron.
– The top of the C has a small flat edge.
– The bottom has a threaded hole with a large threaded screw.
– One end of the screw has a flat edge, similar in size to the top.
– The other end usually has a small metal bar for leverage.
– A G-clamp is used by turning the screw to achieve desired pressure or release.
– Tightening the clamp secures objects between the screw and frame.
– Loosening the clamp releases enough force to move the secured objects.
Woodworking with C-clamps
– Care should be taken when using a G-clamp on wood surfaces.
– The flat edges of the frame can cause indentations and marring.
– Buffering with scrap wood can prevent damage to the clamped surfaces.
– Deep-throated clamps provide greater reach for smaller woodworking tasks.
Stage Lighting and C-clamps
– C-clamps are commonly used to hang stage lighting instruments.

A C-clamp or G-clamp or G-cramp is a type of clamp device typically used to hold a wood or metal workpiece, and often used in, but are not limited to, carpentry and welding. Often believed that these clamps are called "C" clamps because of their C-shaped frame, or also often called C-clamps or G-clamps because including the screw part, they are shaped like an uppercase letter G. However, in fact, they were originally called a carriage maker's clamp, or Carriage Clamp.
