A layout tool is provided for use in marking a work piece to be cut. The layout tool includes a generally flat body having an even surface, a linear edge, locating indicia adjacent the linear edge, and a gripper attached to the flat body. The gripper is movable from an initial position. In the initial position, the gripper is generally aligned with the even surface of the flat body. The gripper can be moved toward the work piece from the initial position to engage the work piece when the flat body overlies the work piece.

A square gauge apparatus configured for being selectively and removably mounted on a leg of a carpenter's square has a ledge having a ledge first surface and an opposite ledge second surface, the ledge first and second surfaces being parallel and offset, a first abutment extending from the ledge and having a first abutment front surface that is perpendicular to the ledge first surface, a second abutment extending from the ledge opposite the first abutment and having a second abutment front surface that is perpendicular to the ledge second surface and parallel to and coplanar with the first abutment front surface, and a slot formed adjacent to the ledge between the first and second abutments, the slot having a slot end surface that is parallel to and coplanar with the first and second abutment front surfaces.

An improved transparent template and positioning device for aligning material to be stitched, marked or cut, the template including two overlapping lines with one or more being translucent and one or more using fluorescent pigment that will overlap their colors to create a third color forming an outline or “halo” effect of enhanced visibility, enabling the darker more precise opaque lines on the ruler to be easily seen or found on light and dark materials. The translucent lines will allow the user to see through the template to the actual material that he or she is working with in order to provide improved viewing and more accurate alignment.

One or more clamping aid tools for mounting to various squares and straight edges, including carpenter squares, framing squares, speed squares or the like, and various straight edges and rulers for easily and accurately positioning various objects, either flat and/or round, magnetic or not. The clamping aid tools can secure these squares and straight edges to various objects while they are being fitted, secured and/or welded together.

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.

A circle compass is provided. The circle compass includes a main body attachable to a router and an adjustable arm. The main body includes a central receiving aperture configured to receive a router bit or shaft therethrough. The adjustable arm is slidably attached to the main body and has a centering pin. The centering pin extends axially outward beyond a bottom side of the main body. The adjustable arm is slidable along an adjustment axis between a retracted position being associated with a smallest hole that can be formed and an extended position being associated with the largest hole that can be formed. The adjustable arm includes a clearance slot that at least partially aligns with the central receiving aperture of the main body through which the rotating portion of the router must extend to form a cut in the work piece.

As described herein, a wall box installation tool may include a template body, one or more hollow pegs, a guide ring, and/or one or more template cards. The template cards may be configured to be installed on a front surface of the template body. A template card may define a plurality of holes therethrough. The guide ring may be configured to be installed within a pre-drilled hole in a wall. Each template card may be associated with a respective electrical device configuration. A subset of bores extending through the hollow pegs may be accessible via the template card when the template card is installed on the front surface of the template body. The wall box installation tool may include one or more fasteners that are configured to install a template card onto the front surface of the template body.
