Draper Aluminium Triangle Scale Graduations Ruler

The Draper Aluminium Triangle Scale Graduations Ruler is a precision measuring tool designed for accurate interpretation of architectural and technical scale drawings. This 300mm aluminium scale rule features a triangular profile with six commonly used scale ratios, making it an essential tool for architects, engineers, surveyors and tradespeople working from detailed plans. Constructed from lightweight yet durable aluminium, this scale ruler provides six different scale graduations across its three faces: 1:20, 1:25, 1:50, 1:75, 1:100 and 1:125. This comprehensive range of scales covers the most frequently encountered ratios in construction and engineering drawings, eliminating the need for manual calculations when translating scaled dimensions to actual measurements. The triangular design allows for quick scale selection and provides a comfortable grip during use, whilst the aluminium construction ensures the graduations remain clearly legible throughout the tool's working life. Supplied in a protective plastic sleeve, the ruler is ideal for site work, office-based plan reading, and technical drawing applications where accurate scale interpretation is critical.
