Protractor Vorel 18797, professional 350 mm length, measuring tool

Vorel 18797 is a professional 350 mm protractor designed for precise angle measurement, marking and transfer. The tool combines a painted steel bar with clear millimetre graduation, a lightweight aluminium foot and an adjustable angle gauge with locking knob, providing a compact instrument suitable for workshop and on-site layout work in woodworking, metalworking and general construction.

Advantages

The protractor's 350 mm steel bar offers a clear, easy-to-read millimetre scale for accurate linear reference when setting or transferring angles. The lightweight aluminium foot reduces tool weight while maintaining stability, and the plastic locking knob secures the adjustable arms to hold the selected angle reliably. The painted finish on the bar improves contrast for graduations and resists everyday wear in workshop conditions.

Suitable for

• Carpentry and joinery angle marking and transfer
• Metalworking layout and angle checks
• Drafting and pattern work requiring durable angle measurement
• On-site construction work and repair tasks

Key specifications

• Overall length of measuring bar: 350 mm
• Adjustable angle gauge integrated with locking mechanism
• Material of foot: lightweight aluminium
• Measuring bar material: painted steel with millimetre graduation
• Locking element: plastic knob for securing arms
• Supplied as a single unit per pack

How to use

Place the aluminium foot against the workpiece edge and open the protractor to align the measuring bar with the reference line or the desired angle. Adjust the angle gauge until the bar matches the required angle, then tighten the plastic knob to lock the arms in position. Use the millimetre graduation on the painted steel bar to mark distances or confirm alignment. For transfer, hold the locked angle against the target workpiece and scribe along the bar or use the edge as a straight reference.

Usage recommendations

For best results, keep the graduation clean and free of debris; check the locking knob for secure engagement before marking; avoid excessive torque on the plastic knob to prevent damage. Store the protractor in a dry place to minimise corrosion of the steel bar and maintain accuracy over time.
