Abstract
A tripod stepladder in which a bracing means includes a sleeve or collar that slides up and down the third or rear leg as the ladder is folded and unfolded. A pail shelf is pivotally attached to the third leg and locks the ladder in the open position, thereby preventing inadvertent closure of the ladder as long as the pail shelf is in the horizontal position.
