An apparatus and method are disclosed having a key having a punch pin and a flat magnet keeps the punch pin in place in a metal v-notch hanger on a back side of a picture frame while a user levels a top edge of the picture frame to mark nail locations. A deck, a turret mounted on a top end of the deck, wherein the turret protrudes from the top end of the deck and the turret is gripped by a user as a handle while hanging a picture on a wall using the apparatus; a hook hanger attached to the front side of the deck for hanging a picture frame from a wire on a back of the picture frame; and a hole through the deck for aligning a push pin to pass through the hole and mark a location for an anchor from which the picture frame hangs.

The present invention includes methods, devices, kits, and components of an apparatus that can assist a user to identify locations of attachment points or openings on a frame and transferring those measurements to a wall for purposes of supporting a picture that is level.

A fence post marking assembly for marking fence post locations includes a pair of pipes that is each positionable in an upright orientation on ground. In this way each of the pipes can mark the proposed location of a fence post. A pair of supports is each coupled to a respective one of the pipes. A rod is positionable in each of the supports thereby facilitating the pipes to be spaced a pre-determined distance apart from each other. In this way the rod can precisely space the proposed locations for fence posts apart from each other. A can of spray paint is provided to mark the proposed location of the fence posts.

The right angle steel worker's layout tool is a tool with a pair of adjustable marking slides that are each used for determining the location of welds and holes on steel beams. Each of the pair of adjustable marking slides is comprised of a lower lock plate, an upper lock plate, a lock knob, and a screw member. The lower lock plate is able to slide along a track groove provided on the tool. The lock knob is used to secure the upper lock plate and the lower lock plate at a designated location along the track groove. The track groove includes a plurality of markings used to designate different dimensions.

The invention relates to a portable appliance for marking a surface, the appliance comprising a housing (2) presenting a front face that is open for passing a marker member that is moved by a device for moving the marker member in a two-dimensional marking zone (Z). The housing is provided with a positioning nose (30) for positioning the appliance over the surface for marking, the positioning nose defining firstly the two-dimensional marking zone (Z) facing the front face of the housing and at a distance from the front face, and secondly an opening (35) extending the top wall for enabling the two-dimensional marking zone to be viewed, the top wall of the housing being fitted with a display screen in such a manner that the screen and the two-dimensional marking zone as seen through the opening of the positioning nose appear simultaneously in the field of view of an operator.
