I'm thinking that I'm not the only who has experienced this situation. You're getting ready to glue up a part or parts for a project and you get the clamps necessary to do this only to find that the clamp(s) that you grabbed are a little too short or longer than necessary. Like many of you I've acquired many clamps over the decades and, back then, the clamp of choice were the Bessey K body ones.
From using them over the years you know that their part number indicates the clamping size. But you also know that the indicated size is very conservative and they can clamp a dimension much larger. A good example of this is their 31 inch clamp which will actually open up to 33 1/4 inches. All of my Bessey clamps are the older style and this situation may not be true for their newer ones. I know if I were clamping a part that was 32 1/2 inches I could just grab a much larger clamp but that becomes cumbersome. So I finally took a few minutes to check and mark all my parallel clamps with their actual capacity. We always know the dimension of the part we're clamping and now I know exactly which clamp to use.
