NOTES

Unless otherwise noted all dimensions were obtained from manufacturers' literature or web sites. No attempt has been made to verify the accuracy of the numbers.
For HB nuts I could only find single dimensions, not ranges, so I have not included these.
I was unable to find official dimensions for Camp Tricams but a number of sites had figures that matched (see for example here and here). Figures for the Camp Ballnuts were obtained in a similar fashion. The official Camp web pages are here: Ballnuts, Tricams.
Even though the Camp Ballnuts, Trango Ballnutz and Wild Country Zeros are really active devices I have decided to make an exception and include them here since they match the size ranges of the other devices shown here.
I'm sorry if I didn't include your favourite brand/model, but if you can point me to an official source with dimensions I will add the information to the chart.
Due to the limitations of HTML table formatting it is possible that the chart will be distorted. This is most likely to occur if the default font is too large.
