or practically anywhere where activities must be performed at heights above ground level conventional ladder stabilizers lack structure to support the side rails of a ladder when a side rail of a ladder flexes twists or otherwise deflects a ladder may fall slip or otherwise fail when a person or object is on the ladder the present invention uses a main bracket adjacent and parallel to a side rail of a ladder the main bracket restrains the ladder side rail from flexing twisting or otherwise deflecting the main bracket may also serve to guide the folding storing and movement of the components of the ladder stabilizer conventional ladder stabilizers lack a foot bracket or a curved foot plate the present invention may comprise a foot bracket for securing the ladder even on uneven surfaces the curved foot plate may serve to enhance stability on uneven or slippery surfaces to adapt to various spaces and surfaces a portion of the ladder stabilizer may be adjusted relative to other portions of the ladder stabilizer in more specifically describing the present invention and as can be appreciated from fig1 the present invention provides a ladder system 10 for safely supporting a ladder 12 when resting on a flat surface 30 or an uneven surface 32 by using a ladder stabilizer 14 the ladder stabilizer 14 may comprise a main bracket 18 which may be situated adjacent and parallel to a side rail 16 of the ladder 12 the main bracket 18 may be connected to a lower arm 20 and a slide arm 26 the slide arm 26 may be inserted telescopically and slidably into an upper arm 24 a foot bracket 22 may be connected to the lower arm 20 and the upper arm 24 a foot.
