enterbay 1/6 scale stand??

does anyone that has these stands? also could some one tell me if the waist clamp is big enough to fit around an 1/4 scale figure's leg... I plan on using the rod and clamp for my custom 1/4 scale figure's base.. Also could someone measure of how wide the clamp goes when the clamp is fully open and extended? All help would be appreciated... If all goes well I may be offering these 1/4 scale stands in the future...
