Why is there no drawing showing where the 6 inches is measured? ditto for all sizes? how can the smallest dimesion be several inches?

A 6-inch clamp will hold an object in its jaws a maximum of 6-inches in size; a 12-inch clamp will hold something twice as big—12-inches, ansd so on. This style of clamp is the greatest: one-hand is all that's needed to tighten or loosen the clamp, unlike a c-clamp which requires at least two hands to work and takes a long time and effort to clamp something.

What does clamp capacity mean? It's listed as 6" to 36" for this clamp. Is 36" or 3 ft. the range of travel?

A six-inch clamp of any type means you can put a six-inch object between its jaws (actual maximum opening would be 6-1/6" to 6-1/4 "); 36" clamp would fit 36" between its jaws.

According to there website as of 2008 their tools are made in China.

What is the throat depth on these clamps?

From throat to lower (inner) part of swivel jaws 1.25"From throat to upper (outer) part of swivel jaws 3-3/16"From throat to middle (center) part of swivel jaws 2.5"

クランプの進化

クイィクグリップの出会いは30年前いまだに使用しています。3回以上変更進化していますが、これは軽いので振り回しが楽で、締め付のフィーリングもコントロールしやすいと感じてます。
