Abstract
This invention allows the use of a stepladder on an uneven surface. The legs of the ladder at their base have a telescopic device, that may be threaded, that allows the individual legs of the ladder to be extended and fixed by means of a securing device. This device makes it possible to extend either leg of the ladder on uneven surfaces. This device will make the use of the ladder safer, quicker and easier on uneven surfaces. The ladder has adapted feet to provide for loss coefficient of friction. Pads on the upper area of the ladder also prevent slippage and damage to surfaces where the ladder is leaning.
