Abstract

A device for determining if a ladder is at a safe angle comprises a casing having a face plate mounted therein. The face plate has an indicator pivotally connected thereto. The indicator has a central axle extending through the face plate, a counterweight affixed to an inner end of the axle behind the face plate and a pointer affixed to an outer end of the axle. The face plate has an outer surface that is provided with visible markings to which the pointer may point to indicate whether a ladder to which the device is attached is set at a safe angle.
