发明名称 Ladder Stabilizers
摘要 A step ladder stabilizer for mounting behind the front step portion and having two adjusting legs which adjust as a slide lock moves vertically within a slot attached to the rear of the ladder steps. When not in use, the ladder stabilizer closes flush against the back of the ladder steps. An alternate embodiment includes a ladder stabilizer for an extension ladder comprising an extending leg and a stabilizer arm with the top of the extending leg attaching to a slide lock that slides along a channel mounted on the side of the ladder. Bolts passing through expansion inserts hold the channel onto each side of the ladder.
