Foot
Note:
If twisted too far, the
handle will start to open, and
eventually the foot will fall
out. Reverse the direction
you’re twisting until the
handle is pointing down,
but the foot still reaches the
track.
Optional step: Prevent the channel lock by loosening over time by using needle nose pliers or
a wrench to tighten the bottom 4 mm hex nut against the rubber foot. Tighten the other hex nut
against the channel lock barrel.
