Rick Gates Share Posted December 7, 2020 I recently made a decision to try out some of Kupo's 3-way and 4-way clamps as a way to lower my gear footprint. The clamps wrap around the riser portion of c-stands and combos, and hold baby spigots and receivers and J-hooks and such. So I measured my stand's riser diameters to see where the clamps could fit. Turns out that the three risers on my c-stands measure (from bottom up), 35mm, 30mm and 25mm. And the risers of the combo stands are 45mm, 40mm, 35mm and 30mm . There's 5mm difference in diameter between each riser. But all my c-stands and combos are Avenger products. Is the 5mm difference standard to all c-stands and combos, or just Avenger?

Rick Gates Author Share Posted December 9, 2020 (edited) Wow, that's way thinner than my Avenger C-stands, which in SAE are 1 3/8", 1 3/16", and 1". The gobo arm on the C-stand is 5/8", same as a baby pin. Good to know. Thanks! Edited December 9, 2020 by Rick Gates Last sentence Quote Link to post Share on other sites
