Angle Finder Pratel 15 cm 180° — manual protractor for measuring angles

The Pratel Angle Finder 15 cm 180° is a manual protractor designed for measuring and transferring angles on workpieces and layouts. With a 15 cm length and a 180° measurement range, this angle finder offers a compact tool for carpentry, metalwork, and general DIY tasks. The device features a clear etched scale and a simple hinge mechanism that allows accurate reading and marking of interior and exterior angles directly on materials.

Advantages

The compact 15 cm size provides good reach while remaining portable for on-site work. The 180° range enables measurement of both acute and obtuse angles, and the clear scale ensures legible readings for precise marking. Its manual hinge construction is simple to operate and durable, allowing repeated use in workshop and field conditions. The tool’s straightforward design reduces setup time when transferring angles between templates and workpieces.

Suitable for

• Carpentry and joinery angle layout and transfer
• Metalworking and sheet metal bending angle checks
• DIY projects requiring accurate angle measurement and marking
• Construction layout tasks and template duplication

Key specifications

• Length: 15 cm
• Measurement range: 0–180°
• Scale type: graduated angle scale with degree markings
• Material: durable metal construction suitable for workshop use
• Operation: manual hinge for angle locking and transfer

How to use

Place the angle finder on the edge or surface of the workpiece, open or close the hinged arms until they align with the two sides of the angle to be measured. Read the angle value from the graduated scale where the pivot indicator aligns with the degree markings. To transfer the measured angle, lock the hinge if available, then place the tool against the target material and mark along the arms. For repeated transfers, keep the arms stable while tracing the lines with a pencil or scribe.

Usage recommendations

For best results, ensure the scale is clean and free of debris before measuring. Use a fine pencil or scribe for precise marking and check alignment in bright light to read the scale accurately. Store the angle finder in a dry place to avoid corrosion and periodically check the hinge for smooth movement and minimal play.
