Contraction ruler KWB 784212 Aluminium 1220 mm

LINE MASTER PRECISION RULE — a durable aluminium contraction ruler designed for precise measurement tasks in construction and woodworking. Made from anodised aluminium with guide grooves, this LINE MASTER precision rule is part of the LINE MASTER system and offers a reliable mm scale applied with a special resin for high resistance to wear. It conforms to accuracy class II according to the German Institute of Physics and measures 1220 mm in length, 58 mm in width and 10 mm in thickness (KWB 784212).

Advantages

The anodised aluminium construction ensures long-term corrosion resistance and stable dimensions; guide grooves allow secure alignment and integration with other LINE MASTER accessories; the mm scale is resin-applied to resist erasing and abrasion; the 1220 mm length provides coverage for typical construction and woodworking layouts, while accuracy class II certifies its suitability for precise measurement work.

Suitable for

• Measuring and marking long straight lines in carpentry and woodworking
• Layout and positioning tasks on construction sites
• Use with LINE MASTER system accessories for guided cuts and alignment
• General workshop measurement tasks requiring a durable, abrasion-resistant ruler

How to use

Place the contraction ruler along the surface or edge to be measured or marked, aligning the guide grooves as needed for a straight reference. Read or transfer measurements from the resin-applied mm scale. For guided cutting or precise alignment, combine the ruler with compatible LINE MASTER accessories or clamps to secure it in place. Store the ruler flat or hung to avoid bending and keep the scale clean to maintain visibility.

Usage recommendations

For best long-term accuracy, avoid exposing the ruler to strong impacts or high temperatures; clean markings with a soft cloth and mild detergent if necessary. When using on finished surfaces, protect the surface with masking tape if clamping pressure could cause damage.
