The present invention 10 discloses a stepladder having a ladder portion 18 that is comprised of rungs 24 and includes two ladder side rails, and a support portion that includes two angularly disposed telescoping legs 20 that provide mechanism for stabilizing the ladder. The telescoping support legs 20 are interconnected to each other and to the ladder side rails by lockable rigid spanner arms 22 . When in use, the spanner arms 22 are locked in an open position to form a tripod formation between the rails while additionally limiting the angle of spread between the ladder portion 18 and the support legs 20 . The present invention 10 also provides a retractable fly assembly 26 at the top of the ladder rails to provide for additional usable working height. A safety belt 36 is provided on the handle for additional support. A series of apertures with lock key fasteners 28 in each of the support legs provide mechanism for the user to securely position the legs at a desired length. The lock key fastener 28 includes a locking pin that engages an aperture in the corresponding leg to secure the desired position.
