Ruler DeWALT DWHT25228-0 300 mm Aluminium Black Yellow

The DeWALT DWHT25228-0 300 mm aluminium ruler is a compact measuring tool engineered for precise, everyday measurements. Constructed from lightweight aluminium and finished in DeWALT's black and yellow scheme, the ruler combines visibility with durability for use on job sites, in workshops, or at home. Its 300 mm length provides a convenient size for common carpentry, metalworking and craft tasks while remaining easy to store in toolboxes or carry in pockets.

Advantages

The aluminium construction offers a balance of strength and low weight, reducing fatigue during extended use while resisting bending under normal measuring loads. High-contrast markings and the black and yellow finish improve readability in varied lighting conditions. The compact 300 mm size makes the ruler practical for measuring short distances and checking edges, and the rigid profile maintains accurate straight edges for marking and scoring.

Suitable for

• Carpentry and woodworking measurements
• Metalworking layout and marking
• DIY projects and hobby crafts
• On-site quick measurements and checks

Key specifications

• Length: 300 mm
• Material: aluminium
• Finish: black and yellow
• Scale type: metric graduations
• Form factor: straight, rigid profile

How to use

Place the ruler flat along the edge or surface to be measured, aligning the zero mark with the starting point. Read the metric graduations directly at the end point or use the ruler as a straight edge to mark lines with a pencil or scribe. For repeated measurements, maintain the ruler's flat contact with the workpiece to ensure consistency. Store the ruler in a dry place to reduce surface wear and prevent dirt accumulation that could obscure the markings.

Usage recommendations

Use the ruler for short, accurate metric measurements and as a straight edge for marking; avoid using it as a pry bar or exposing it to heavy bending forces to preserve its straightness and measurement accuracy.
