Multifunction Angle Ruler Expert+ MN-83-030 300 x 100 mm with Sliding Arm and Spirit Level

The Multifunction Angle Ruler Expert+ MN-83-030 300 x 100 mm with Sliding Arm and Spirit Level is a compact measuring and marking tool designed for carpentry, metalwork and general construction. It combines a fixed L-shaped body with an adjustable sliding arm and an integrated spirit level to measure, transfer and set angles accurately on workpieces. The 300 x 100 mm dimensions make it suitable for layout tasks on boards, panels and small structural elements while the sliding arm increases reach and adaptability for varied jobs.

Advantages

This angle ruler provides precise angle transfer and repeatable layout thanks to its rigid L-shaped frame and adjustable sliding arm. The built-in spirit level aids quick horizontal or vertical alignment without separate tools. Its compact size and clear geometry simplify marking and measuring on smaller components, and the sliding arm allows for finer adjustments and improved contact with irregular surfaces. The tool is lightweight and easy to position, reducing setup time during routine measuring tasks.

Suitable for

• Marking and transferring angles on timber, plywood and composite boards
• Layout and alignment tasks in joinery and cabinetmaking
• Metalwork angle checks and small-scale fabrication
• Setting and checking angles during installation of fittings and trims
• General workshop measuring and quick on-site checks

Key specifications

• Overall size: 300 x 100 mm
• Design: L-shaped angle ruler with adjustable sliding arm
• Feature: Integrated spirit level for horizontal/vertical alignment
• Primary use: Measuring, marking and transferring angles
• Material: durable construction suitable for workshop use

How to use

Place the fixed leg of the angle ruler against a reference edge of the workpiece and extend the sliding arm to the required reach. Align the arm to the desired marking or angle, using the spirit level to verify horizontal or vertical position as needed. Mark through the ruler's edge or along the arm to transfer the measured angle onto the workpiece. For repeated layouts, lock the sliding arm position if the tool provides a fixing mechanism, then use the ruler as a template to repeat the same angle on other pieces.

Usage recommendations

Keep the ruler clean and free of debris for accurate contact with the workpiece. Use light, consistent pressure when marking to avoid shifting the tool. When measuring critical angles, verify alignment with the spirit level in two planes and, if necessary, re-check measurements with a secondary square or protractor.
