Abstract: For a level having a pair of arms nested together but which are pivotally connected so as to be angularly separable from the nested condition and also moveable together from the separated condition to the nested condition, a hollow carrier for carrying the level constructed of flat panels one panel of which can be folded to permit the carrier to be slipped over one of the arms when the arms are angularly separated and then be refolded to provide for the separated arms to be moved into the nested condition.
Abstract: A pair of arms pivotally connected for relative rotation and a brake actuated by a rotatable lever positionable from either side of the level to restrain the arms against relative rotation or to allow the arms to freely rotate.
