What G-clamp sizes are available?
G-clamps are available in many different sizes.
It is always important to use a G-clamp of an adequate size to hold your workpiece, otherwise there is a risk of bending the frame and damaging the screw.
|The size of a G-clamp, and whether it is large enough for a particular workpiece, can be measured by its jaw opening and throat depth, which together determine the tool's clamping capacity.|
The jaw opening of a clamp is how far the mouth of the jaws can open.
The size of the jaw opening usually increases by 25mm (1") with each size of G-clamp.
The smallest jaw opening available is 25mm (1" approx.).
The largest jaw opening available is 300mm (12" approx.).
|The throat depth is how deep the jaws of a clamp are, and is measured by the distance from the top edge of the jaws to the side of the frame.|
The throat depth can vary, depending on the model of G-clamp.
Some models are specially designed with a deeper throat for clamping wider workpieces without increasing the whole size of the clamp.
The smallest throat depth available is 16mm (⅝").
The largest throat depth available is 200mm (8" approx.).
