Brass Rule for High Frequency Welding,
made in England by Stephenson & Blake limited's Sheffield foundry.
Stephenson & Blake only use brass which is most suitable for forming whilst giving minimal height distortion during the bending process. Whilst there are cheaper materials available, their philosophy of using the highest grades available to give the best results, have seen the company acknowledged as a quality supplier.
All Stephenson & Blake rules are produced to the standard 26” length (660mm).
