## Long description

The Grand drawing T-tube Grand GR-0070 is a drafting accessory with a rigid 7 mm diameter tube and an adjustable overall length from 46 to 70 cm. It functions as a stable guide for ruled lines and measured strokes when used with drawing instruments. The design supports precise, repeatable line work in technical drawings, diagrams and layouts where controlled stroke width and consistent spacing are required.
Advantages
The adjustable length allows users to adapt the guide to different drawing formats and sheet sizes while maintaining a steady guide path. A consistent 7 mm diameter provides compatibility with a range of drawing instruments and ensures predictable contact behavior. The construction is intended to deliver stable guidance and reduce hand-induced deviations during drawing, contributing to higher accuracy and uniform lines.
Suitable for
Architectural drafting and layout work
Engineering diagrams and technical sketches
Student drafting practice and classroom use
Repetitive line work where uniform stroke width is important
Key specifications
Tube diameter: 7 mm
Adjustable length range: 46–70 cm
Material: rigid drawing tube (visual: metal or rigid composite)
Intended use: manual guidance for drawing instruments and pens
Compatibility: works with standard drafting pens and instruments requiring a 7 mm guide
How to use
Set the T-tube to the required length within the 46–70 cm range and secure any adjustment mechanism according to the product's locking system. Place the tube on the drawing surface aligned to the desired guide line and run the drawing instrument along the tube edge to produce a controlled stroke. Use steady, even pressure and maintain the tube's position to ensure a consistent line. For different sheet sizes reposition and readjust the tube length as needed.
Usage recommendations
For best results, pair the T-tube with pens and instruments that match its 7 mm guide profile, keep the tube clean of debris to avoid marking the paper, and check the adjustment lock before drawing to prevent slippage.
