Is the fixed part of the leg too long for you? There Is a threaded rod that releases the fitting that holds the lower legs (when you use the trigger). Shortening the top part/fixed part seems like you'd need to either rethread the rod on make a new connection depending on which end of the tub/leg you cut. Not sure I've described that well.... This video will show the disassembly (it's on a tripod but the concept is the same). I think what I'm describing will make more sense if you watch some of it.
