Kent Set Square 260mm 45 Deg 260B45

Kent Set Square 260mm 45° is a large format, clear acrylic set square featuring a 45/45/90° angle configuration and a calibrated ruler edge measuring to 16cm. The 260mm size provides a generous working span well suited to the demands of technical drawing, architectural drafting and geometric construction at secondary level, allowing students to draw long, accurate lines with a single placement of the instrument. The clear acrylic construction allows students to see the drawing surface beneath, supporting accurate alignment and precise placement across all technical drawing tasks.

The 45° set square is one of the two essential set squares in technical drawing practice, used to produce lines at 45°, 90° and, when combined with a 60° set square, a full range of standard angles including 15°, 30°, 75° and 105°. This makes it an indispensable tool for isometric drawing, parallel line construction, angle bisection and geometric problem solving across visual arts, design and technology, and mathematics programs.

Students can use the Kent Set Square 260mm 45° for a wide range of technical drawing tasks including constructing parallel and perpendicular lines, producing isometric projections, drawing architectural elevations and plans, and completing geometry exercises requiring accurate 45° and 90° angle construction. The large format is particularly well suited to A3 and larger drawing formats commonly used in senior visual arts and design folios.

The calibrated ruler edge provides an additional measuring function, allowing students to mark accurate increments directly from the set square without needing to switch to a separate ruler. The hanging hole at the top of the instrument allows for easy storage and display in the classroom, keeping instruments organised and readily accessible.

Suitable for secondary art, design and technology, mathematics and technical drawing programs, Kent Set Square 260mm 45° is a durable, well-made instrument that meets the requirements of senior students working to a high standard of technical drawing accuracy and precision.

Kent Set Square 260mm 45° is used by placing the set square flat on the drawing surface with the desired edge aligned to the drawing direction. Use the 90° corner to draw perpendicular lines, the 45° angle for diagonal construction, and the calibrated ruler edge for measuring and marking increments. When used in combination with a 60° set square and T-square or parallel ruler, a full range of standard drawing angles can be produced accurately and efficiently.

Store the set square flat or hang via the hole at the top edge to prevent warping and protect the acrylic surface from scratching.
