Parallel ruling at any angle - a precision drafting arm for the Mars 661 A3 drawing board

The Staedtler Mars 660 20 is a drafting arm accessory designed specifically for the Mars 661 A3 drawing board, providing parallel line ruling at any angle across the full drawing surface.

A drafting arm transforms a basic drawing board into a precision parallel ruling system. The 660 20 attaches to the left edge of the 661 A3 board and allows the ruling head to travel vertically with perfect parallelism, while the ruling head itself rotates to set any angle. This eliminates the need for a T-square for parallel horizontal lines and for a separate set square for most standard angles - both functions are integrated in the drafting arm head. The scale allows the angle to be set with precision and the locking mechanism holds the head firmly at the selected angle.

Compatible specifically with the Staedtler Mars 661 A3 drawing board. The Mars 660/661 system is a trusted professional and educational drawing board setup for technical drawing, architecture and design disciplines where hand drafting is still practised.

The Staedtler Mars 660 20 drafting arm is an essential accessory for anyone using the Mars 661 A3 board who wants to upgrade from T-square and set square to an integrated parallel ruling system.
