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. | |||
Jaw opening |
||||
 |
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.). |
|||
Throat depth |
||||
 |
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.). |
