Abstract: A leveler attachment including a first leg assembly and a second leg assembly, the first leg assembly and the second leg assembly each including a lever, a shaft movable by adjustment of the lever, a locking mechanism coupled to an end of the shaft, the locking mechanism including a gear lock, a rotatable gear, and a rack to interact with teeth of the rotatable gear. The rotatable gear is configured to rotate on the rack when in an unlocked state causing inverse motion of the first leg assembly relative to the second leg assembly. Adjusting the locking mechanism to the unlocked state includes lifting the lever which lowers the shaft and disengages the teeth of the rotatable gear from the gear lock thereby permitting the rotatable gear to rotate along the rack.

Abstract: Apparatuses, systems, and methods pertaining to an anchor device are provided herein. The anchor device can be used to anchor a ladder to a support object such as a roof and stabilizes the ladder during use of the ladder. The anchor device includes a main body having a base with a first end and a second end, a fixed clamping bracket at one end of the base and an elongated opening or track extending along the base. A moving clamping assembly includes a moving clamping bracket and a cam lever or actuator, and the moving clamping assembly is configured to slide along the track to adjust a position of the moving clamping bracket relative to the fixed clamping bracket. Pivoting the lever tightens the moving clamping bracket against the object and locks the moving clamping assembly in position for a firm clamping hold. The anchor device may also include a tether assembly for being tethered to a ladder.
