Abstract
A level including an elongate hollow frame with two sidewalls and a topwall extending therebetween, a topnotch defined by the walls which have notch-defining edges including non-vertical surfaces, and a vial within the topnotch. A vial-mounting structure includes a vial-holding member and a locking member movably secured with respect to the vial-holding member. The vial-holding member is configured for resting on the non-vertical notch-edge surfaces. The locking member includes frame-engaging portions which press upwardly against a frame inner surface to pull the vial-holding member downwardly against the non-vertical notch-edge surfaces, thereby securing the vial-holding member to the frame. A method for securing a vial-mounting structure to the level by providing the vial-mounting structure, which includes the vial-holding member, and pulling the vial-holding member downwardly against the non-vertical notch-edge surfaces by a force from inside the frame, thereby securing the vial-holding member to the frame.
