A stirrup swivel attachment comprising:

• a first horizontal web portion having a midpoint and a longitudinal axis;
• a horizontal u-shaped member having a second horizontal web portion with a midpoint, a longitudinal axis and two ends, and having flange portions that extend vertically upward from the ends of the second horizontal web portion;
• a pivot means for pivotally connecting the first and second horizontal web portions at the midpoints thereof;
• and
• a stop means disposed on the second horizontal web portion at a point removed from the midpoint thereof for stopping the first horizontal web portion when the first horizontal web portion is pivoted about the pivot means so that the longitudinal axes of the first and second horizontal web portions cannot become vertically aligned.

A stirrup comprising:

• a horizontal stirrup body portion having two ends;
• two upwardly converging stirrup side portions attached to the ends of the stirrup body portion, each stirrup side portion terminating in a distal end;
• a first horizontal tubular member disposed between the distal ends of the stirrup side portions;
• a first horizontal web portion disposed above the first horizontal tubular member and attached thereto;
• a horizontal u-shaped member having a second horizontal web portion with a midpoint, a longitudinal axis and two ends, and having flange portions that extend vertically upward from the ends of the second horizontal web portion;
• a pivot means for pivotally connecting the first and second horizontal web portions at the midpoints thereof;
• and
• stop means for stopping the first horizontal web portion when the first horizontal web portion is pivoted about the pivot means so that the longitudinal axes of the first and second horizontal web portions cannot become vertically aligned.
