Abstract: A trimmer head for a string trimmer mower, including a trimmer head housing having a string retention portion and a coupler portion rotatably attached to the string retention portion, the string retention portion having a first string retainer for releasably retaining a first cutting string. In addition, the string retention portion has a second string retainer for releasably retaining a second cutting string. The second string retainer is preferably circumferentially displaced on the string retention portion from the first string retainer. In a preferred embodiment, the first string retainer has a slidable clamp disposed in the interior and accessible from the exterior. The clamp is constructed and arranged for sliding relative to the base between a clamping position for selectively retaining the string in place through centrifugal force in the string retention portion, and a release position for user replacement of the first cutting string without tools.

Abstract: A lock template includes an elongated body member that defines a substantially rectangular first opening having a first length and a first width and an elongated first member. The elongated first member is configured to be removably-inserted into first end recesses of the body such that the first member is located at least partially within the first opening. The first member, when inserted in the first end recesses of the body, defines a wall of a second opening having a length substantially equal to the first length and a width smaller than the first width. The second opening is configured to guide a cutting instrument to form a mortise for a lock component in a passageway component. When the first member is inserted into the first end recesses a longitudinal central axis of the first insert member is offset from a central axis between the first end recesses of the body.
