The Jakar Adjustable Set Square (200mm) is a precision instrument designed for architects, engineers, students, and professional designers who require exact angle measurements for technical drawing and geometric projects. It offers the versatility of an adjustable protractor combined with the stability of a traditional set square, though users should handle the adjustment mechanism with care to maintain its high-precision calibration over time.

The Jakar Adjustable Set Square is constructed from high-quality, durable materials suitable for technical and professional drafting.
Yes, it is highly recommended for students in architecture, engineering, and design programs.
Yes, it comes with a canvas pouch for protection and convenient storage.
While effective for detailed work, the 200mm size is better suited for A3 or A4 paper; larger plans may require a larger drafting tool.
Regularly check the alignment against a known 90-degree reference line on your drafting table to ensure the square remains calibrated.
Ensure the locking washer is seated correctly and verify that the knob is tightened to the limit without over-torquing.
Ensure the tool is used under adequate lighting and keep the acrylic surface free of pencil graphite dust.
To begin using the Jakar Adjustable Set Square, ensure the hinge mechanism is clean and free of debris. To set an angle, loosen the central locking knob, align the arm with your desired degree marking on the protractor scale, and tighten the knob securely before use. For maintenance, keep the tool in the provided canvas pouch when not in use to prevent accidental drops or surface scratches. Avoid using abrasive cleaning agents on the scale markings; a simple wipe with a soft, dry cloth is sufficient to keep the instrument in peak condition.
